Location Type or Attribute Type Description
geometry.arbitrary.<group>.index integer[ ] List of indexes (if no index is present, the
index is implicitly defined by the scope).
geometry.arbitrary.<group>.indexedValue integer,
float,
double, or
string
List of values. The base type can be integer,
float, double, or string.
geometry.arbitrary.<group>.elementSize integer This optional attribute determines the array
length of each scoped element. This is used
by some renderers, for example, PRMan
maps this to the "[n]" portion of a
RenderMan type declaration: "uniform
color[2]"
Geometry > pointcloud
pointcloud Point cloud geometry. A point cloud is the
simplest form of geometry and only
requires point data to be specified.
geometry.point See polymesh.
geometry.arbitrary.<group> See polymesh.
Geometry > subdmesh
subdmesh Subdivision surfaces geometry. Subdivision
surfaces (Subds) are similarly structured to
polygonal meshes.
geometry.facevaryinginterpolateboundary A single integer flag, used by PRMan in the
RiHierarachicalSubdivisionMeshV call by
renderer output. Ignored in other
renderers.
See the RenderMan documentation for
more information.
