[JAVA3D] AW: [JAVA3D] Printing a Canvas3D?

Vincent, I think you can configure your Canvas3D to render to an offscreen-buffer. You can then render the contents of the offscreen buffer onto a normal (non-3D) Canvas, which in effect replaces your Canvas3D on screen. You should then also be able to print this offscreen buffer using the print

Re: [JAVA3D] Collision Detection

Anders, You need to put the class in from of the USE_BOUNDS variable. For example: wEnter = new WakeupOnCollisionEntry(shape, WakeupOnCollisionEntry.USE_BOUNDS); Also make sure that the "javax.media.j3d.*" package is imported at the top of the file. Hope this helps Dean - Original Messag

Hi Vincent, I just came across one of the samples included in the Java3D 1.2 SDK. It is named "OffScreenCanvas3D" and I think it contains everything you need to solve your problem. Have a look into "OffScreenCanvas3D.java" and "PrintFromButton.java" (which does NOT already print the image on your

Hi Pasi Not is posible to remove a transformgroup in a live or compiled scene, j3d optimizes the scene and some transformgroups could be removed . The solution is detach the parent branchgroup, remember first set the flag ALLOW_DETACH in the BranchGroup. > Hello, > > I have a TransformGroup th

Re: [JAVA3D] dual processor performance

Evan, I have a dual CPU PII 450 running NT 4.0 and Java 3d does use both CPUs. Based upon non-scientific comparisons between my machine and a co-workers single CPU PII 450 I believe I get significantly better results using my dual CPU computer. Regards, Gregory Bradford Evan Drumwright wrote:

Hi Marina, IMHO you mean some geometry as wire frame ? You need PolygonAttributes.POLYGON_LINE. Put this PolygonAttributes-object into your Appearance-object and apply that to your Shape3D (that is consisiting of geometry, appearance). Gernot [EMAIL PROTECTED] http://www.janet.de

Try looking at the Forums pages too at http://forum.java.sun.com under the Java3D section. This question has been raised there also. I offered a possible solution there, but I'm not sure if it would work. Someone may have added something to the discussion though. > -Original Message- >

Re: [JAVA3D] Two different scenes in two windows

Hello,:) I found through experience that placing the two objects very far apart is the easiest way to get 2 scenes. As long as the clipping distance of each view doesn't overlap the other geometry, there is no problem with rendering speed either. Mojtaba
