Here is my best advice....
Don't use IndexAnything.
Unless it makes your code simpler. Java3d will just expand it anyway and
send the unindexed version to the card.

> int[] miCoordIndices = new int[200];

> ga.setCoordRefFloat(mfCoordinates);
> ga.setCoordinateIndices(0, miCoordIndices);
>
> now if I setValidVertexCount(200), it'll have an exception like
> "initialVertexIndex + validVertexCount > vertexCount". (InitialIndex is
> 0).
> It seemed to apply to the vertex array. Even if I setValidVertexCount(80),
