Location Type or Attribute Type Description

geometry.poly.vertexList integer[ ] The vertexList describes the vertex data of a

mesh. There is a vertex at each edge

intersection. The value of the vertexList is

used as an index into the geometry.point.P

list which stores the actual object

coordinates of each unique point. Many

indices in a vertexList can index the same

point in the geometry.point.P list. This

saves space as a vertex is described as a

simple integer rather then the three floating

point values required to describe a 3D

geometry point (x, y, z).

geometry.vertex.N float3[ ] List of vertex normals.

geometry.vertex.UV float2[ ] List of texture coordinates (per vertex, non

face-varying).

Geometry > geometry.arbitrary.<group>

geometry.arbitrary.<group> This group contains any sort of user data,

such as custom attributes, defined in other

applications. Texture coordinates, for

example, are defined using a group called

st.
