Detailed Description

A subdivision mesh primitive

Subdivision meshes can have a list of arbitrary tags. Each tag can have integer, real or string values. Tags that are used in refinement:

  • int crease[]
    A list of pairs of vertices defining edges
  • real crease[]
    The crease weights for each edge
  • int corner[]
    A list of corner vertices
  • real corner[]
    The crease weights for corner
  • int interpolateboundary
    Deprecated: Determines how point attributes are interpolated
  • int facevaryinginterpolateboundary
    Deprecated: Determines how vertex attributes are interpolated
  • int osd_vtxboundaryinterpolation
    Determines how point attributes are interpolated (values match the enum in OpenSubdiv.
  • int osd_fvarlinearinterpolation
    Determines how vertex attributes are interpolated (values match the enum in OpenSubdiv.
  • int osd_creasingmethod
    Determines the creasing rule (values match the enum in OpenSubdiv)
  • int osd_trianglesubdivision
    Determines triangle subdivision smoothing for Catmull-Clark subdivision (values match the enum in OpenSubdiv)
