Remarks
Lower-level entry point: Method that generates new UVs inconstant with the mesh defined by the VertexBuffer/IndexBuffer according to the parameters specified in the FTextureAtlasDesc The underlying code uses Isometeric approach (Iso-Charts) in UV generation. This assumes that the caller has already generated the mesh adjacency information. 'true' if the UV generation succeeded, 'false' if it failed.
Parameters
| Name | Description |
|---|---|
| InTextureAtlasDesc | Description of the texel resolution of the desired texture atlas. |
| VertexBuffer | Positions of vertices |
| IndexBuffer | Triangle definitions |
| AdjacencyBuffer | 3 entries for each face, each entry is the face index of the face that is adjacent to the given face. -1 means no face. |
| StatusCallBack | Allows for termination of the UV generation. |
| UVVertexBuffer | Resulting UVs |
| UVIndexBuffer | Connectivity for the UVs |
| VertexRemapArray | Array that remaps the vertices split by the UV generation to the source vertices. |
| MaxStretch | On Input, The maximum amount of stretch between (0 - none and 1 - any), on Output the actual max stretch used. |
| MaxChartNumber | On Input Maximum number of charts required for the atlas. If this is 0, will be parameterized solely on stretch. Note, not a hard limit - isochart will stop when a valid charting is found that is greater or equal to this number. On Output: Number of charts actually generated |
