Dear All,
I've added a new online chapter to my Java 3D games book
about programming an articulated, moveable figure. It's at:
http://fivedots.coe.psu.ac.th/~ad/jg/ch115/
The figure is coded in Java 3D without the use of VRML
geometry. Instead we've used our own LatheShape3D class
which was deve
I have some
trouble creating a partially transparent object with Java3D for
DirectX:
TransparencyAttributes ta = new
TransparencyAttributes(TransparencyAttributes.FASTEST,
0.5f);
However, the
resulting object is completely transparent (i.e. invisible)
!
I also tried
other tranparency
Thank you for your concern but can you clarify where
should i put those lines,before i close the
window(Closing the Widow Event)?
Best Regards

I
think there is another explanation for what Jean is observing: Windows is
detecting that the window is no longer fully active, and then it discards large
blocks of unused data. That phenomenon is visible with *any* windows program.
It's part of how Windows handle memory usage.
Besides th
Thank you for being so fast in answering but in my
application i trace memory used by it and every time i
close my JDialog only 5MB is released(From about 25 MB
Jump) and when i open it again it jumps 25MB so i
donot think that that java reuses memory and this
means that i have about 20MB increase
The TransparencyAttributes seem to be correct and I have never seen this
effect (using Windows/DirectX and Linux/GLX). Possibly the reason for this
problem can be found somewhere else in your scene graph!?

Ok, so *you* have a classical memory leak. The resources that your JDialog
is using (including java3d resources) are not freed, and besides that each
time you open your dialog you create new resources!
There are 2 solutions:
1. make sure that all resources are freed.
2. try to reuse the dialog an
All right, so forcing the GC by iconifying the window does not really "free"
the memory, i.e. the memory is not given back to the OS.
I know it is the case for all windows application, it even works if you iconify
the windows console !! (if your program is run from a console).
Anyway, it is u

hi,

I agree that this sounds basically more like a directX project. You don't really gain
anything from platform independance or java working inside the virtual machine (in
fact these both play somewhat against you) if you are working only to replicate

Hello,
I believe there was a demo of such a system at the Web3D event at
Siggraph. Perhaps one of the BOF's.
Perhaps trolling the Web3D consortium's web site.

I'm using DirectX Java 3D on my Radeon 9700 and all

surprised me). I'm guessing your Appearance isn't set up properly... Here's a
