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

typedef std::vector<Vector4, STLAllocator<Vector4, CategorisedAlignAllocPolicy<MEMCATEGORY_GEOMETRY> > > Ogre::EdgeData::TriangleFaceNormalList

Array of 4D vector of triangle face normal, which is unit vector orthogonal to the triangles, plus distance from origin.

Use aligned policy here because we are intended to use in SIMD optimised routines.

Definition at line 91 of file OgreEdgeListBuilder.h.

typedef vector<char>::type Ogre::EdgeData::TriangleLightFacingList

Working vector used when calculating the silhouette.

Use std::vector<char> instead of std::vector<bool> which might implemented similar bit-fields causing loss performance.

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.
