Combining this with Java Webstart i get flickering problems, the repaint

if i use WebStart and j2Sdk 1.3.x no problems occour ...

Not much help but I think about a week ago one of the Sun guys posted a
compatibility table that said in effect that the only j3d that 'works'
with jdk1.4 is j3d1.3b2.
That confused me as I'd thought that j3d1.2.1_04 was released
specifically as a jdk1.4 compatible version!
So maybe try j3d1.3b2
this doesn't help much , the effect keeps.
The problem must be in the combination with WebStart .
Has anyone expierience with webstart and j3d ?

You are using the direct X version of Java3d, and my guess is that it doesn't

Hi,
I have TriangleStripArray where the coordinates are created
using J3DBuffer.
When trying to find the closest point on the surface (from the
mouse x, y location) the PickTool code stops working.
The following code works fine using normal geometry, but not
when using nio buffers.
