Detailed Description

A collection of Bone objects used to animate a skinned mesh.

Remarks:: Skeletal animation works by having a collection of 'bones' which are actually just joints with a position and orientation, arranged in a tree structure. For example, the wrist joint is a child of the elbow joint, which in turn is a child of the shoulder joint. Rotating the shoulder automatically moves the elbow and wrist as well due to this hierarchy.

: So how does this animate a mesh? Well every vertex in a mesh is assigned to one or more bones which affects it's position when the bone is moved. If a vertex is assigned to more than one bone, then weights must be assigned to determine how much each bone affects the vertex (actually a weight of 1.0 is used for single bone assignments). Weighted vertex assignments are especially useful around the joints themselves to avoid 'pinching' of the mesh in this region.

: Therefore by moving the skeleton using preset animations, we can animate the mesh. The advantage of using skeletal animation is that you store less animation data, especially as vertex counts increase. In addition, you are able to blend multiple animations together (e.g. walking and looking around, running and shooting) and provide smooth transitions between animations without incurring as much of an overhead as would be involved if you did this on the core vertex data.

: Skeleton definitions are loaded from datafiles, namely the .skeleton file format. They are loaded on demand, especially when referenced by a Mesh.

		BoneHandleMap &	boneHandleMap
	)			const `[virtual]`

Build the bone handle map to use with Skeleton::_mergeSkeletonAnimations.

See also:: getStateCount.

void Ogre::Skeleton::_dumpContents ( const String & filename ) [protected]

Debugging method.

virtual void Ogre::Resource::_fireLoadingComplete ( bool wasBackgroundLoaded ) [virtual, inherited]

Firing of loading complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters:

wasBackgroundLoaded

Whether this was a background loaded event

virtual void Ogre::Resource::_firePreparingComplete ( bool wasBackgroundLoaded ) [virtual, inherited]

Firing of preparing complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters:

wasBackgroundLoaded

Whether this was a background loaded event

virtual void Ogre::Resource::_fireUnloadingComplete ( void ) [virtual, inherited]

Firing of unloading complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

virtual Animation* Ogre::Skeleton::_getAnimationImpl	(	const String &	name,
		const LinkedSkeletonAnimationSource **	linker = `0`
	)			const `[virtual]`

Internal accessor for animations (returns null if animation does not exist).

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::_getBoneMatrices ( Matrix4 * pMatrices ) [virtual]

Populates the passed in array with the bone matrices based on the current position.

Remarks:: Internal use only. The array pointed to by the passed in pointer must be at least as large as the number of bones. Assumes animation has already been updated.

virtual void Ogre::Skeleton::_initAnimationState ( AnimationStateSet * animSet ) [virtual]

Initialise an animation set suitable for use with this skeleton.

Remarks:: Only recommended for use inside the engine, not by applications.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::_mergeSkeletonAnimations	(	const Skeleton *	source,
		const BoneHandleMap &	boneHandleMap,
		const StringVector &	animations = `StringVector()`
	)			`[virtual]`

Merge animations from another Skeleton object into this skeleton.

Remarks:: This function allow merge two structures compatible skeletons. The 'compatible' here means identically bones will have same hierarchy, but skeletons are not necessary to have same number of bones (if number bones of source skeleton's more than this skeleton, they will copied as is, except that duplicate names are unallowed; and in the case of bones missing in source skeleton, nothing happen for those bones).

: There are also unnecessary to have same binding poses, this function will adjust keyframes of the source skeleton to match this skeleton automatically.

: It's useful for exporting skeleton animations separately. i.e. export mesh and 'master' skeleton at the same time, and then other animations will export separately (even if used completely difference binding pose), finally, merge separately exported animations into 'master' skeleton.

Parameters:

	source	Pointer to source skeleton. It'll keep unmodified.
	boneHandleMap	A map to translate identically bone's handle from source skeleton to this skeleton. If mapped bone handle doesn't exists in this skeleton, it'll created. You can populate bone handle map manually, or use predefined functions build bone handle map for you. (

See also:: _buildMapBoneByHandle, _buildMapBoneByName)

Parameters:

animations

A list name of animations to merge, if empty, all animations of source skeleton are used to merge. Note that the animation names must not presented in this skeleton, and will NOT pick up animations in linked skeletons (

See also:: addLinkedSkeletonAnimationSource).

virtual void Ogre::Skeleton::_notifyManualBonesDirty ( void ) [virtual]

Internal method for marking the manual bones as dirty.

virtual void Ogre::Skeleton::_notifyManualBoneStateChange ( Bone * bone ) [virtual]

Internal method for notifying that a bone is manual.

virtual void Ogre::Resource::_notifyOrigin ( const String & origin ) [virtual, inherited]

Notify this resource of it's origin.

Definition at line 420 of file OgreResource.h.

virtual void Ogre::Skeleton::_refreshAnimationState ( AnimationStateSet * animSet ) [virtual]

Refresh an animation set suitable for use with this skeleton.

Remarks:: Only recommended for use inside the engine, not by applications.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::_updateTransforms ( void ) [virtual]

Updates all the derived transforms in the skeleton.

virtual void Ogre::Skeleton::addLinkedSkeletonAnimationSource	(	const String &	skelName,
		Real	scale = `1.0f`
	)			`[virtual]`

Allows you to use the animations from another Skeleton object to animate this skeleton.

Remarks:: If you have skeletons of identical structure (that means identically named bones with identical handles, and with the same hierarchy), but slightly different proportions or binding poses, you can re-use animations from one in the other. Because animations are actually stored as changes to bones from their bind positions, it's possible to use the same animation data for different skeletons, provided the skeletal structure matches and the 'deltas' stored in the keyframes apply equally well to the other skeletons bind position (so they must be roughly similar, but don't have to be identical). You can use the 'scale' option to adjust the translation and scale keyframes where there are large differences in size between the skeletons.

Note:: This method takes a skeleton name, rather than a more specific animation name, for two reasons; firstly it allows some validation of compatibility of skeletal structure, and secondly skeletons are the unit of loading. Linking a skeleton to another in this way means that the linkee will be prevented from being destroyed until the linker is destroyed.

You cannot set up cyclic relationships, e.g. SkeletonA uses SkeletonB's animations, and SkeletonB uses SkeletonA's animations. This is because it would set up a circular dependency which would prevent proper unloading - make one of the skeletons the 'master' in this case.

Parameters:

	skelName	Name of the skeleton to link animations from. This skeleton will be loaded immediately if this skeleton is already loaded, otherwise it will be loaded when this skeleton is.
	scale	A scale factor to apply to translation and scaling elements of the keyframes in the other skeleton when applying the animations to this one. Compensates for skeleton size differences.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Resource::addListener ( Listener * lis ) [virtual, inherited]

Register a listener on this resource.

See also:: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::Skeleton::calculateSize ( void ) const [protected, virtual]

Calculate the size of a resource; this will only be called after 'load'.

Implements Ogre::Resource.

Definition at line 460 of file OgreSkeleton.h.

virtual void Ogre::Resource::changeGroupOwnership ( const String & newGroup ) [virtual, inherited]

Change the resource group ownership of a Resource.

Remarks:: This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters:

newGroup

Name of the new group

static void Ogre::StringInterface::cleanupDictionary ( ) [static, inherited]

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const [virtual, inherited]

Method for copying this object's parameters to another object.

Remarks:: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

dest

Pointer to object to have it's parameters set the same as this object.

Definition at line 301 of file OgreStringInterface.h.

References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

virtual Animation* Ogre::Skeleton::createAnimation	(	const String &	name,
		Real	length
	)			`[virtual]`

Creates a new Animation object for animating this skeleton.

Parameters:

	name	The name of this animation
	length	The length of the animation in seconds

Implements Ogre::AnimationContainer.

Reimplemented in Ogre::SkeletonInstance.

virtual Bone* Ogre::Skeleton::createBone	(	const String &	name,
		unsigned short	handle
	)			`[virtual]`

Creates a brand new Bone owned by this Skeleton.

Remarks:: This method creates an unattached new Bone for this skeleton and assigns it a specific name and handle. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

Parameters:

	name	The name to give to this new bone - must be unique within this skeleton.
	handle	The handle to give to this new bone - must be unique within this skeleton.

virtual Bone* Ogre::Skeleton::createBone ( const String & name ) [virtual]

Creates a brand new Bone owned by this Skeleton.

Remarks:: This method creates an unattached new Bone for this skeleton and assigns it a specific name.Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

Parameters:

name

The name to give to this new bone - must be unique within this skeleton. Note that the way OGRE looks up bones is via a numeric handle, so if you name a Bone this way it will be given an automatic sequential handle. The name is just for your convenience, although it is recommended that you only use the handle to retrieve the bone in performance-critical code.

virtual Bone* Ogre::Skeleton::createBone ( unsigned short handle ) [virtual]

Creates a brand new Bone owned by this Skeleton.

Remarks:: This method creates an unattached new Bone for this skeleton and assigns it a specific handle. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created a root bone.

Parameters:

handle

The handle to give to this new bone - must be unique within this skeleton. You should also ensure that all bone handles are eventually contiguous (this is to simplify their compilation into an indexed array of transformation matrices). For this reason it is advised that you use the simpler createBone method which automatically assigns a sequential handle starting from 0.

virtual Bone* Ogre::Skeleton::createBone ( void ) [virtual]

Creates a brand new Bone owned by this Skeleton.

Remarks:: This method creates an unattached new Bone for this skeleton. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

: Note that this method automatically generates a handle for the bone, which you can retrieve using Bone::getHandle. If you wish the new Bone to have a specific handle, use the alternate form of this method which takes a handle as a parameter, although you should note the restrictions.

bool Ogre::StringInterface::createParamDictionary ( const String & className ) [protected, inherited]

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:: This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

className

the name of the class using the dictionary

Returns:: true if a new dictionary was created, false if it was already there

Definition at line 184 of file OgreStringInterface.h.

References OGRE_LOCK_MUTEX.

void Ogre::Skeleton::deriveRootBone ( void ) const [protected]

Internal method which parses the bones to derive the root bone.

Remarks:: Must be const because called in getRootBone but mRootBone is mutable since lazy-updated.

virtual void Ogre::Resource::escalateLoading ( ) [virtual, inherited]

Escalates the loading of a background loaded resource.

Remarks:: If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual const String& Ogre::Resource::getOrigin ( void ) const [virtual, inherited]

Get the origin of this resource, e.g.

a script file name.

Remarks:: This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

Definition at line 418 of file OgreResource.h.

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) const [inherited]

Definition at line 222 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) [inherited]

Retrieves the parameter dictionary for this class.

Remarks:: Only valid to call this after createParamDictionary.

Returns:: Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

Definition at line 217 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter ( const String & name ) const [virtual, inherited]

Generic parameter retrieval method.

Remarks:: Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters:

name

The name of the parameter to get

Returns:: String value of parameter, blank if not found

Definition at line 270 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

const ParameterList& Ogre::StringInterface::getParameters ( void ) const [inherited]

Retrieves a list of parameters valid for this object.

Returns:: A reference to a static list of ParameterDef objects.

virtual Bone* Ogre::Skeleton::getRootBone ( void ) const [virtual]

Gets the root bone of the skeleton: deprecated in favour of getRootBoneIterator.

Remarks:: The system derives the root bone the first time you ask for it. The root bone is the only bone in the skeleton which has no parent. The system locates it by taking the first bone in the list and going up the bone tree until there are no more parents, and saves this top bone as the root. If you are building the skeleton manually using createBone then you must ensure there is only one bone which is not a child of another bone, otherwise your skeleton will not work properly. If you use createBone only once, and then use Bone::createChild from then on, then inherently the first bone you create will by default be the root.

virtual BoneIterator Ogre::Skeleton::getRootBoneIterator ( void ) [virtual]

Get an iterator over the root bones in the skeleton, ie those with no parents.

virtual size_t Ogre::Resource::getSize ( void ) const [virtual, inherited]

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 301 of file OgreResource.h.

virtual size_t Ogre::Resource::getStateCount ( ) const [virtual, inherited]

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

Definition at line 429 of file OgreResource.h.

virtual bool Ogre::Skeleton::hasAnimation ( const String & name ) const [virtual]

Returns whether this skeleton contains the named animation.

Implements Ogre::AnimationContainer.

virtual bool Ogre::Skeleton::hasBone ( const String & name ) const [virtual]

Returns whether this skeleton contains the named bone.

virtual bool Ogre::Skeleton::hasManualBones ( void ) const [virtual]

Are there any manually controlled bones?

Definition at line 359 of file OgreSkeleton.h.

virtual bool Ogre::Resource::isBackgroundLoaded ( void ) const [virtual, inherited]

Returns whether this Resource has been earmarked for background loading.

Remarks:: This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 365 of file OgreResource.h.

virtual bool Ogre::Resource::isLoaded ( void ) const [virtual, inherited]

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual bool Ogre::Resource::isManuallyLoaded ( void ) const [virtual, inherited]

Is this resource manually loaded?

Definition at line 289 of file OgreResource.h.

virtual bool Ogre::Resource::isPrepared ( void ) const [virtual, inherited]

Returns true if the Resource has been prepared, false otherwise.

Definition at line 324 of file OgreResource.h.

virtual bool Ogre::Resource::isReloadable ( void ) const [virtual, inherited]

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 282 of file OgreResource.h.

virtual void Ogre::Resource::load ( bool backgroundThread = false ) [virtual, inherited]

Loads the resource, if it is not already.

Remarks:: If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters:

backgroundThread

Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Skeleton::loadImpl ( void ) [protected, virtual]

virtual void Ogre::Resource::postLoadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions after the load process, but before the resource has been marked as fully loaded.

Note:: Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Reimplemented in Ogre::Mesh.

Definition at line 189 of file OgreResource.h.

virtual void Ogre::Resource::postUnloadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions after the unload process, but before the resource has been marked as fully unloaded.

Note:: Mutex will have already been acquired by the unloading thread.

Definition at line 199 of file OgreResource.h.

virtual void Ogre::Resource::preLoadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions before the load process, but after the resource has been marked as 'loading'.

Note:: Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Definition at line 182 of file OgreResource.h.

virtual void Ogre::Resource::prepare ( bool backgroundThread = false ) [virtual, inherited]

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters:

backgroundThread

Whether this is occurring in a background thread

virtual void Ogre::Resource::prepareImpl ( void ) [protected, virtual, inherited]

Internal implementation of the meat of the 'prepare' action.

Reimplemented in Ogre::Material, Ogre::Mesh, and Ogre::PatchMesh.

Definition at line 203 of file OgreResource.h.

virtual void Ogre::Resource::preUnloadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions before the unload process.

Note:: Mutex will have already been acquired by the unloading thread.

Definition at line 194 of file OgreResource.h.

virtual void Ogre::Resource::reload ( void ) [virtual, inherited]

Reloads the resource, if it is already loaded.

Remarks:: Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Skeleton::removeAllLinkedSkeletonAnimationSources ( void ) [virtual]

Remove all links to other skeletons for the purposes of sharing animation.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::removeAnimation ( const String & name ) [virtual]

Removes an Animation from this skeleton.

Implements Ogre::AnimationContainer.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Resource::removeListener ( Listener * lis ) [virtual, inherited]

Remove a listener on this resource.

See also:: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Skeleton::reset ( bool resetManualBones = false ) [virtual]

Resets the position and orientation of all bones in this skeleton to their original binding position.

Remarks:: A skeleton is bound to a mesh in a binding pose. Bone positions are then modified from this position during animation. This method returns all the bones to their original position and orientation.

Parameters:

resetManualBones

If set to true, causes the state of manual bones to be reset too, which is normally not done to allow the manual state to persist even when keyframe animation is applied.

virtual void Ogre::Skeleton::setAnimationState ( const AnimationStateSet & animSet ) [virtual]

Changes the state of the skeleton to reflect the application of the passed in collection of animations.

Remarks:: Animating a skeleton involves both interpolating between keyframes of a specific animation, and blending between the animations themselves. Calling this method sets the state of the skeleton so that it reflects the combination of all the passed in animations, at the time index specified for each, using the weights specified. Note that the weights between animations do not have to sum to 1.0, because some animations may affect only subsets of the skeleton. If the weights exceed 1.0 for the same area of the skeleton, the movement will just be exaggerated.

Parameters:

virtual void Ogre::Resource::setBackgroundLoaded ( bool bl ) [virtual, inherited]

Tells the resource whether it is background loaded or not.

Remarks:

See also:: Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 375 of file OgreResource.h.

virtual void Ogre::Skeleton::setBindingPose ( void ) [virtual]

Sets the current position / orientation to be the 'binding pose' i.e.

the layout in which bones were originally bound to a mesh.

virtual void Ogre::Skeleton::setBlendMode ( SkeletonAnimationBlendMode state ) [virtual]

Sets the animation blending mode this skeleton will use.

virtual bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)			`[virtual, inherited]`

Generic parameter setting method.

Remarks:: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

	name	The name of the parameter to set
	value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns:: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList ) [virtual, inherited]

Generic multiple parameter setting method.

Remarks:: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

paramList

Name/value pair list
