IndexExtensions Class
Namespace: Stride.ExtensionsAssembly: Stride.Rendering.dll
public static class IndexExtensions| Name | Description | |
|---|---|---|
| Methods | ||
| CompactIndexBuffer(MeshDraw) | Compacts the index buffer from 32 bits to 16 bits per index, if possible. |
|
| GenerateIndexBuffer(MeshDraw, VertexDeclaration) | Generates an index buffer for this mesh data. |
|
| GenerateIndexBufferAEN(IndexBufferBinding, VertexBufferBinding, CommandList) | ||
| GenerateIndexBufferAEN(MeshDraw) | Generates the index buffer with dominant edge and vertex information. Each triangle gets its indices expanded to 12 control points, with 0 to 2 being original triangle, 3 to 8 being dominant edges and 9 to 11 being dominant vertices. |
|
| GenerateIndexMapping(VertexBufferBinding, CommandList, String[]) | Generates an index mapping with the specified vertex elements. If no vertex elements are specified, use the whole vertex. |
|
| GetReversedWindingOrder(MeshDraw, out Byte[]) | Reverses the winding order of an index buffer. Assumes it is stored in TriangleList format. Works on both 32 and 16 bit indices. |
|
| RemoveIndexBuffer(MeshDraw) | Expand vertices using index buffer (if existing), and remove it. |
|
| ReverseWindingOrder(MeshDraw) | Reverses the winding order of an index buffer. Assumes it is stored in TriangleList format. Works on both 32 and 16 bit indices. |
