There is something weird here...is the problem case dependent ?
I went back and checked whether the USE_COORD_INDEX_ONLY bit was
ignored when you retrieve an IndexedGeometryArray from GeometryInfo.
As I indicated previously, in my special case at least, IT IS NOT.
IIRC, if you run NormalGenerator
Hi Artur,
When you are *retrieving* the IndexedGeometryArray from the
GeometryInfo, are you specifying the flag "USE_COORD_INDEX_ONLY"
as a parameter to geomInfo.getIndexedGeometryArray( flag..) ?
IIRC, it also takes other flags such as NIO, ByRef, etc.
If you're already aware of it, then please

The Java3D tutorial bundle has an example called TexturedText3DApp.java

On Text2D being a Shape3D rather than a geometry, my opinion ($0.02)

Nearly a year back I had posted a fairly long note about getting

Hi:
what kind of projection ( parallel / perspective ) are you using ?
Also, what kind of behaviors are you using for effecting zooming -
those supplied by the API or your own ?
If you are using perspective proj., then the zoom classes supplied
with the J3D API should work. If you are using para
an identity matrix and carries no other
info. unless you specify so.
