Detailed Description

This class contains the information required to describe the edge connectivity of a given set of vertices and indexes.

Remarks:: This information is built using the EdgeListBuilder class. Note that for a given mesh, which can be made up of multiple submeshes, there are separate edge lists for when

void Ogre::EdgeData::updateFaceNormals	(	size_t	vertexSet,
		const HardwareVertexBufferSharedPtr &	positionBuffer
	)

Updates the face normals for this edge list based on (changed) position information, useful for animated objects.

Parameters:

	vertexSet	The vertex set we are updating
	positionBuffer	The updated position buffer, must contain ONLY xyz

void Ogre::EdgeData::updateTriangleLightFacing ( const Vector4 & lightPos )

Calculate the light facing state of the triangles in this edge list.

Remarks:: This is normally the first stage of calculating a silhouette, i.e. establishing which tris are facing the light and which are facing away. This state is stored in the 'triangleLightFacings'.

Parameters:

lightPos

4D position of the light in object space, note that for directional lights (which have no position), the w component is 0 and the x/y/z position are the direction.
