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.

Parameter |
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 |
