[JAVA3D] Collision Detection

Hi there, I'm trying to implement the collision detection between two Primitive spheres, each with their own associated Object properties. However for some reason when these spheres collide and I try to capture the terminal object node with ScreenGraphPath.getObject(), I am being told that the l

[JAVA3D] Texture map curiosity fixed!

Back in January I emailed a sample app around demonstrating that using both the Sun VRML loader and the Xj3D loader textures would disappear if I destroyed a canvas, then created a new one (in the context of switching between one and four views). Anyway.. just reporting that the latest release o

[JAVA3D] Shinyness Funnyness

Howdy All, I 'm wondering if anyone out there has expereinced unusual behavior out of Java3D with regards to the shinyness of their shapes/scene? I have a problem that pops up now and again, and am wondering if other folks have had similar problems. Thanks, Noah =

Sun recommended a ratio of 3000:1 for the back clip to front clip ratio for a 16 bit Z-buffer. If you'd like to read some technical details about this we have it documented on our website at: http://www.starfireresearch.com/services/java3d/supplementalDocumentation.html >From what is being descr

I just tested the program in my system (jdk1.4.1/java3d1.3/OpenGL/NVidia Riva TNT2). It behaved same as it did in yours. This discussion is so informative. Thank you all for reponding to this question. Mingtian Ni On Tue, 29 Oct 2002, Florin Herinean wrote: > Hi, it's clear a problem with the fr

[JAVA3D] AW: [JAVA3D] Again on "Geometry looks transparent"

Hi, it's clear a problem with the front clip distance. Not sure if it's related to Z Buffering. I tryied with both 16 and 32 bit buffers and it behaves exactly the same, no difference. However, the ball displays correctly if the front clip dist. is 1e-3 but it is drawn after the cylinder if the FC

Re: [JAVA3D] Again on "Geometry looks transparent"

Hmmm... looks like a Z-Buffering problem, if I zoom out a lot and then rotate I can see odd effects but at the default zoom it looks fine. From what Alessandro says about the commenting the clip set out it appears you are setting the front/back clip ranges too far away for your cards Z-Buffer. su.

Re: [JAVA3D] Again on "Geometry looks transparent"

Ops !!! The "bug" as it appear at my machine could be fixed as with only one comment out: View view = universe.getViewer().getView(); view.setFrontClipPolicy(View.VIRTUAL_EYE); view.setBackClipPolicy(View.VIRTUAL_EYE); view.setBackClipDistance(4 * (m_viewWidth + m_viewHeight + m_viewDepth

Re: [JAVA3D] Again on "Geometry looks transparent"

Hi !! I could reproduce your bug. The green ball is always visible doesnot matter the position it is. I could fix it, but I am not sure how it will impact your application. I just comment out some lines of your view: View view = universe.getViewer().getView(); // view.setFrontClipPolicy(View.

Re: [JAVA3D] Again on "Geometry looks transparent"

I can not see any error either, this is with Jdk1.4.1 j3d1.3 OpenGL on NT4 with an ATI Rage Pro 32mb card. Have you tried using a differant machine with different VGA card? I'm guessing it's a driver/card issue with your machine. Good luck, Jason. >>> [EMAIL PROTECTED] 29/10/20

[JAVA3D] pls do not send bmp's or big files

Hello all, I am not aware of the netiquette of this list, but i doubt it states: 'We encourage you to send your pictures as 1MB bmp's' :-) I mean no offense, this is rather a request (btw. What does the moderator think about this?) as in my home i have slow connection (64K ISDN) and it's not very
