)

Builds smooth vertex normals over a mesh.

• “smooth” because smoothing groups are not supported here

• takes angles into account for correct cube normals computation

To use 32bit indices pass a pointer in dFaces and set wFaces to zero. Alternatively pass a pointer to wFaces and set dFaces to zero.

Parameters:

• nbTris – [in] Number of triangles

• nbVerts – [in] Number of vertices

• verts – [in] Array of vertices

• dFaces – [in] Array of dword triangle indices, or null

• wFaces – [in] Array of word triangle indices, or null

• normals – [out] Array of computed normals (assumes nbVerts vectors)

• flip – [in] Flips the normals or not

Returns:

True on success.
