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.
