Translate subobject selections, so selected vertices, edges, or surface areas (faces or patches) in the input model is still selected in the output.

#define CONVERT_USESOFTSEL   0x0002

Translate soft selections.

Also, in the case of patches turning into meshes with more vertices, soft selections are used to interpolate between selected patch corners and non-selected ones.

#define CONVERT_SEL_LEVEL   0x0004
#define CONVERT_PATCH_USEQUADS   0x0010

When converting to a Patch model, create quad patches for any quads in the input mesh or poly mesh.

Otherwise, turns everything into triangle patches.

#define CONVERT_NO_RELAX   0x0020

Indicates in patch-to-mesh conversions that the Relax parameters in the patch must be ignored.

Function Documentation

CoreExport void setPatchIntrFunc ( INTRFUNC  fn)
CoreExport void ConvertMeshToPatch ( Mesh &  m,
PatchMesh &  pm,
DWORD  flags = 0 
)

Converts a mesh to a patch mesh.

CoreExport void ConvertPatchToMesh ( PatchMesh &  pm,
Mesh &  m,
DWORD  flags = 0 
)

Converts a patch mesh to a mesh.

CoreExport void ConvertPatchToMeshWithMapping ( PatchMesh &  pm,
Mesh &  m,
Tab< int > *  mapping,
DWORD  flags = 0 
)

This method converts a Patch to Trimesh, similarly to the method ConvertPatchToMesh().

However, the new method also stores the mapping from the Mesh's faces to the PatchMesh's patches in the 'mapping' parameter.

Parameters
[in]pm- The patch to convert
[in]m- The mesh object we set our converted TriMesh onto.
[out]mapping- After conversion, this array will be filled a mapping from the Mesh's faces to the PatchMeshs faces.
[in]flags- One of the ConversionFlags
CoreExport void RelaxMesh ( Mesh &  mesh,
float  value,
int  iter,
BOOL  boundary,
BOOL  saddle 
)
