Member Enumeration Documentation

enum Ogre::RenderOperation::OperationType

The rendering operation type to perform.

Enumerator:

OT_POINT_LIST	A list of points, 1 vertex per point.
OT_LINE_LIST	A list of lines, 2 vertices per line.
OT_LINE_STRIP	A strip of connected lines, 1 vertex per line plus 1 start vertex.
OT_TRIANGLE_LIST	A list of triangles, 3 vertices per triangle.
OT_TRIANGLE_STRIP	A strip of triangles, 3 vertices for the first triangle, and 1 per triangle after that.
OT_TRIANGLE_FAN	A fan of triangles, 3 vertices for the first triangle, and 1 per triangle after that.

Member Data Documentation

IndexData* Ogre::RenderOperation::indexData

Index data - only valid if useIndexes is true.

Definition at line 75 of file OgreRenderOperation.h.

size_t Ogre::RenderOperation::numberOfInstances

The number of instances for the render operation - this option is supported in only a part of the render systems.

Definition at line 81 of file OgreRenderOperation.h.

OperationType Ogre::RenderOperation::operationType

The type of operation to perform.

Definition at line 66 of file OgreRenderOperation.h.

const Renderable* Ogre::RenderOperation::srcRenderable

Debug pointer back to renderable which created this.

Definition at line 77 of file OgreRenderOperation.h.

bool Ogre::RenderOperation::useGlobalInstancingVertexBufferIsAvailable

A flag to indicate that it is possible for this operation to use a global vertex instance buffer if available.

Definition at line 85 of file OgreRenderOperation.h.

bool Ogre::RenderOperation::useIndexes

Specifies whether to use indexes to determine the vertices to use as input.

If false, the vertices are simply read in sequence to define the primitives. If true, indexes are used instead to identify vertices anywhere in the buffer, and allowing vertices to be used more than once. If true, then the indexBuffer, indexStart and numIndexes properties must be valid.

Definition at line 72 of file OgreRenderOperation.h.

VertexData* Ogre::RenderOperation::vertexData

Vertex source data.

Definition at line 63 of file OgreRenderOperation.h.
