Location Type or Attribute Type Description
xform.<group>.rotateX
(not inherited)
double4 The first number indicates the angle of
rotation. The remaining three define the
axis of rotation (1.0/0.0/0.0 for X axis).
xform.<group>.rotateY
(not inherited)
double4 The first number indicates the angle of
rotation. The remaining three define the
axis of rotation (0.0/1.0/0.0 for Y axis).
xform.<group>.rotateZ
(not inherited)
double4 The first number indicates the angle of
rotation. The remaining three define the
axis of rotation (0.0/0.0/1.0 for Z axis).
xform.<group>.scale
(not inherited)
double3 Scale on the xyz axes.
xform.<group>.matrix double16 A 4x4 homogenous matrix transformation.
xform.<group>.origin double Resets the transformation to identity,
ignoring everything prior to it in the
transformation stack. This is synonymous
with the RiIdentity() attribute in the
Renderman specification.
Note: The presence of this attribute is all
that is required to set the transform to
identity. The value is ignored but the type
must be double.
Geometry
Geometry > Polymesh
Polymesh Polygonal mesh geometry. A polygonal
mesh is formed of points, a vertex list
(defining vertices) and start index list
(defining faces). Additional information,
such as normals and arbitrary data, can also
be defined.
geometry.point.N float3[ ] List of point normals.
