Re: [JAVA3D] browser

You need to first download the Java Plugin for browsers (JRE 1.2 -> JRE 1.3). Then go download the jre version of Java 3D which may come with the original install. I am not sure. That is a quick summary though. Good luck -Original Message- From: Stefano Scarpanti [S

Re: [JAVA3D] Smoke

To do fog you would need a particle system. I am not sure if that exists in Java 3D right now... You may be able to fake particles using 3D points. -Original Message- From: Matthew Flagg [SMTP:[EMAIL PROTECTED]] Sent: Wednesday, February 02, 2000 9:33 AM

Re: [JAVA3D] ViewPlatform view policy

Thanks Joerg, I can attach or set new ViewPlatforms but when I run my program, it comes up with a blank Canvas3D. When I don't mess with the ViewPlatform at all, my scenes display correctly. Is there some flag or variable I'm missing that tells the Locale where the correct ViewPlatform is? The r

Re: [JAVA3D] dual processor performance

Dan, I think you read this on the performance guide. However, it doesn't say that the engine knows how to use native threads only on Solaris, it says that when running in the solaris environment, be sure that native threads are enabled. Green threads will not take advantage of multiple CPU's.

[JAVA3D] Raster Class

Please consider this: The Raster class in J3D 1.1.2 running under JDK 1.2.1 has no way to specify a "hot spot." The hot spot is very important to us when the center of a symbol (icon) needs to be positioned on a spot on the earth (our model). The same symbol also needs to be picked. The Raster on

Re: [JAVA3D] Any way to get a Canvas3d inside a JInternalFrame?

Look at http://java.sun.com/products/jfc/tsc/articles/mixing/index.html The problem is that Swing's JInternalFrame is a lightweight component, but Canvas3d is a heavyweight one. Mixing them is a bit tricky. Good luck, Jacob Nikom Rob Rodgers wrote: > > Hello, listmembers. > > I'm in the middle

Re: [JAVA3D] dual processor performance

I remember an experience on jdk 1.1.* , with a dual processor box on win NT: the JVM was only using one of the CPU and we ended up with a max use of 50%, we have solved this by having several JVM but this was a solution only as we had a server which could be fragmented, would not suit a J3D app;

Sorry people, got my lists mixed up. >From where I see the conversation going the thinking is similar. Smoke might work with a particle system. I have been trying to write one myself, and if I ever get something working I'll be happy to post it. The one I'm working on however will generate Iso-S

Hi Evan, >From what I remember reading in the Java 3D docs, the engine knows to use native threads only on Solaris ( don't remember if it was about Sun or Sun/Intel machines ). Eventually you can try the free Solaris program from Sun ( pay only for media and delivery ) and see wat's happening. On
