Defines a basic polygon mesh from an existing prim.

This converts an existing prim to a Mesh type, preserving any existing transform data.

Parameters:

  • prim – The existing prim to convert to a mesh

  • faceVertexCounts – The number of vertices in each face of the mesh

  • faceVertexIndices – Indices of the positions from the points to use for each face vertex

  • points – Vertex positions for the mesh described in local space

  • normals – Values to be authored for the normals primvar

  • uvs – Values to be authored for the uv primvar

  • displayColor – Values to be authored for the display color primvar

  • displayOpacity – Values to be authored for the display opacity primvar

Returns:

UsdGeomMesh schema wrapping the converted UsdPrim
