[JAVA3D] boolean set operations API

2003-12-14 Thread Danbalby
Hi, I've developed an API to apply boolean operations on solids and an application based on the constructive solid geometry that uses it. They are freely available at http://primordial.cic.unb.br/lcmm/projetos/boolean/. For those who are going to try it, let me know about critics, sugestions and e

> How about t3d.set(new Vector3d(-10.0, -10.0, -10.0))? It doesn't work. What does work is this: t3d.lookAt(new Point3d(5,5,20), new Point3d(0,0,0), new Vector3d(0,1,0)); t3d.invert(); vp.getViewPlatformTransform().setTransform(t3d); The trick is to use INVERT function! Thanks to you all.

[JAVA3D] Do Soundscape / AuralAttributes really work?

Hi, I played around a little bit with Soundscape and AuralAttributes but with absolutely no result. With every (also extreme) parameter I tried for the AuralAttributes there is no change with the sound. After I was not sure if it was my fault, I tested the Java3D-Demo "ReverbateSound" delivered wi

2003-12-14 Thread Ondrej Rohlik
Dear all! After the whole afternoon and evening of experiments, reading Java3D API documentation and tutorial I decided to ask a (trivial?) question. I have set of objects (ColorCubes) close to the origin of coordinate system. I can't use setNominalViewingTransform() as I want to set up the "eye

Hi, I think you have picked your cube using PickCanvas!? Its method picAll()/pickClosest()/... returns a PickResult object. There you can find a Method getClosestIntersection() which returns a PickIntersection object. There you can find a method int getClosestVertexCoordinates() which returns the

Hello friends, I have constructed an own cube with QuadArray . It looks nice and works well. How can I pick a corner of this cube and move this picked point with mouseDrag to change this shape online? Do I need an IndexedQuadArray ? Thank you for some support. C. Ratsch ===
