geometry.numVertices
float[ ]
The number of vertices in each curve.
The following XML is from a Scene Graph
that creates 3 linear curves with 3
segments:
<attr type="GroupAttr"
inheritChildren="false">
<attr type="IntAttr"
name="degree" tupleSize="1">
<sample value="1 " size="1"
time="0"/>
</attr>
<attr type="FloatAttr"
name="knots" tupleSize="1">
<sample value="0.0 " size="1"
time="0"/>
</attr>
<attr type="IntAttr"
name="numVertices"
tupleSize="1">
<sample value="4 4 4 " size="3"

The numVertices list defines the index
ranges of the knots used by each curve.
