Re: [JAVA3D] "Random" parts of a Shape3D disappear when clipped

[Enrique Dumas]

Are you using geometry by reference or by copy with your shapes ?

I've been trying to figure this out for two days, I'd appreciate any ideas on this.

 

I have a ModelClip with 2 enabled planes and a Shape3D (QuadArray with a few hundred polygons). When I clip the shape with a single plane it works fine, but when the second plane comes in, some polygons of the shape disappear with the planes in certain positions, only to re-appear if I move one of the planes some more. Even stranger - when some of the polygons disappear, if I rotate the whole scene, they flicker (appear/disappear).

 

If I use a ColorCube istead of my Shape3D (the rest of the tree (BranchGroups) remaining the same) it works fine.

 

I've attached 2 screenshots. In the bad picture, one of the planes is translated.

 

Java2 - 1.3.0_02

Java3D - 1.2.1_04

I've tried with J3D 1.3 beta - same problem
