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)
