Hi Ian and Florin,
This problem of when and when not to use TGs was examined
by Chien and and to some extent by me sometime last
year IIRC. I think it is a compromise and mostly app. specific.
Chien gave the useful stat. that TG + Shape3D takes ~3.6K

Checked with Kelvin and he confirmed that this flag doesn't work,
and based on my testing it doesn't with Java 3D 1.3.1 beta1.
Kelvin has filed Bug Id 4805797 to have it fixed in 1.3.1 beta2.
Hope this helps

Hi All,
I've been running into problems in trying to get consistent pick
hits on indexed geometries with the BY_REFERENCE bit set.
If I do not choose to turn on that bit, however, picking works
very well.
Specifically, the problems with the BY_REF bit are as follows:
1. If I try to pick an index

Hi Kovalan,
I think what you are looking for is a composite transformation
matrix that gets you from object to viewplatform coordinates.
This is probably what the eye coordinates in OpenGL means, i.e.,
before clipping, perspective division, and transformation to window
space.
You may also want t
Hi Kovalan,
If the object-to-viewworld and viewplatform-to-viewworld matrices
are turning out to be identities, then it means that you're not
manipulating the TransformGroups holding your Shape3D/ViewPlatform
using Mouse/OrbitBehavior, and that your geometry is actually
viewworld aligned.
There
Any chance we can get a callback facility in OrbitBehavior
for transformChanged(..) notifications in the next release of
Java 3D 1.3 ? - this is not critical but would be very convenient !!!
Thanks and Regards

Has depth-sorting transparent geometries by invoking
View.setTransparencySortingPolicy(View.TRANSPARENCY_SORT_GEOMETRY)
been reported to result in a possible memory leak ?
Seem to be running into one in my app.

Are the debuggers which come with Forte CE v3.0 and NetBeans v3.3
any good ? Don't seem to be having much luck in putting them to good
use - they seem to freeze more often than not in the middle of a
session. Just wondering whether I goofed in the installation
kinda unlikely...
