I' ve just a question about how setValidVertexCount( ) works in
IndexedGeometryArray class.
The documentation says:
Sets the valid vertex count for this GeometryArray object. This count specifies the
number of vertices actually used in
rendering or other operations such as picking and collision. This attribute is
initialized to vertexCount.
What is the function of this method in IndexedGeometryArray classes or is this
method just ignored ?
What happens if I use indices of vertices over the range of the valid vertex count
?
Why is there no equivalent method setValidIndexCount( ) which allows me to specify
the number of indices rendered ?
Same questions for setInitialVertexIndex().

Does the method setInitialVertexIndex() work correct ? If so, a possible workaround
for the bug would be to set the vertices starting at the highest index down to 0
and use setInitialVertexIndex(x), which prevent rendering of the vertices from 0 to
x-1. Am I right ?
