typedef vector<Edge>::type Ogre::v1::EdgeData::EdgeList |
typedef std::vector<Vector4, STLAllocator<Vector4, CategorisedAlignAllocPolicy<MEMCATEGORY_GEOMETRY> > > Ogre::v1::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.
typedef vector<char>::type Ogre::v1::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::v1::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.
vertexSet | The vertex set we are updating |
positionBuffer | The updated position buffer, must contain ONLY xyz |
void Ogre::v1::EdgeData::updateTriangleLightFacing | ( | const Vector4 & | lightPos | ) |
Calculate the light facing state of the triangles in this edge list.
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. |
EdgeGroupList Ogre::v1::EdgeData::edgeGroups |
All edge groups of this edge list.
bool Ogre::v1::EdgeData::isClosed |
Flag indicate the mesh is manifold.
TriangleFaceNormalList Ogre::v1::EdgeData::triangleFaceNormals |
All triangle face normals.
It should be 1:1 with triangles.
TriangleLightFacingList Ogre::v1::EdgeData::triangleLightFacings |
Triangle light facing states.
It should be 1:1 with triangles.
TriangleList Ogre::v1::EdgeData::triangles |
Main triangles array, stores all triangles of this edge list.
Note that triangles are grouping against edge group.
