[JAVA3D] Particle animations

Hello, I have a Java class which spits out X, Y, Z positions of particles at each time step. Does anyone know where I could pick up a simple piece of code which takes X,Y,Z positions and draws spheres and changes at each time step. I looked through the demos that came with Java3d. I'm quite co

Re: [JAVA3D] Reducing CPU-Load with postSwap

We have tried this technique in many ways this since Java3D 1.1.2. But there are some hidden problems. First, on Win9x and NT, System.currentTimeMillis() does not have that good of accuracy. For example, if you were to print out System.currentTimeMillis() in a loop, the values will jump at appro

[JAVA3D] Reducing CPU-Load with postSwap

The Java3D Render Thread uses 100% of the CPU to maximize the frame rate. But for the human eye it doesn't make a big difference if it's 25fps or 100fps. The CPU-Power is often needed for other calculations. So what do you think of my suggestion of overriding the postSwap method of Canvas3D like t

Dave: You have uncovered 2 bugs in Java3D and both of which will be fixed in 1.2.1 beta. Bug1: TYPE_3BYTE_BGR does make a copy on windows, the way to avoid copy on windows is to use TYPE_CUSTOM Bug2: ByReference texture and raster does not work with immediate mode

Re: [JAVA3D] Canvas Capture

There is a RecordingCanvas3D class in NCSA Portfolio. Info on where to find it is posted periodically, so check the archive. You can use it to capture canvas images. There is also a free software called "Smacker", which you can use to put these images together into a .avi file. The visual quality

Re: [JAVA3D] Canvas Capture

Okay, I must be losing it. Using PointSound seems very simple, but I cannot get the sound to eminate from anywhere but the origin (0,0,0). I place the sound at (75,0,0), and set an attenuation curve that makes it so that you must be within 5 units to hear the noise. But no matter how I change t
