D3DXWELDEPSILONSFLAGS enumeration
Options for welding together vertices.
Syntax
enum _D3DXWELDEPSILONSFLAGS {
D3DXWELDEPSILONS_WELDALL = 1,
D3DXWELDEPSILONS_WELDPARTIALMATCHES = 2,
D3DXWELDEPSILONS_DONOTREMOVEVERTICES = 4,
D3DXWELDEPSILONS_DONOTSPLIT = 8
};
Constants
-
D3DXWELDEPSILONS_WELDALL
-
Weld together all vertices that are at the same location. Using this flag avoids an epsilon comparison between vertex components.
-
D3DXWELDEPSILONS_WELDPARTIALMATCHES
-
If a given vertex component is within epsilon, modify partially matched vertices so that both components are identical. If all components are equal, remove one of the vertices.
-
D3DXWELDEPSILONS_DONOTREMOVEVERTICES
-
Instructs the weld to allow only modifications to vertices and not removal. This flag is valid only if D3DXWELDEPSILONS_WELDPARTIALMATCHES is set. It is useful to modify vertices to be equal, but not to allow vertices to be removed.
-
D3DXWELDEPSILONS_DONOTSPLIT
-
Instructs the weld not to split vertices that are in separate attribute groups. When the ID3DXMesh::Optimize method is called with the D3DXMESHOPT_ATTRSORT flag, then the D3DXMESHOPT_DONOTSPLIT flag will also be set. Setting this flag can slow down software vertex processing.
