Hey--   I am finally getting good values out my head tracker using the JavaComm API to read the serial port--   However, I am not sure what form the data must be in in order to use setHeadIndex() --from previous emails you will note that this is the correct way to use head tracking with the

[JAVA3D] Future of Java Media

Hello--   I have heard from reliable sources that the Java Media APIs are dramatically cutting back and RIFing many talented people. At first this would seem really bad but in thinking about it I know that much opportunity comes out of these situations.   Two things I would like to see discu

[JAVA3D] Recipe for using an HMD

Hello again--   In my efforts to use Java3D on as many display devices as I can find in my lab, I have now moved on to our HMD.  Let's leave head tracking out of this discussion and just focus on getting the signals out to the device--a Virtual Research V8--   The HMD has two VGA inputs (one

[JAVA3D] Stereo

2001-10-17 Thread Alejandro Terrazas
I found the stereo setup to be rather straightforward, once I found a graphics card that Java3D supports in stereo mode. I am assuming we are talking about the Windows environment with shutterglasses. Always test your setup outside of Java3D if possible to verify it is working. The issues were:

[JAVA3D] What's the beauty of Interpolators?

2001-10-05 Thread Alejandro Terrazas
I occasionally wonder why the Interpolator class with an Alpha object is necessary. Could everything be done in a Behavior that wakes up on elapsedtime--or is that the point? Does the Alpha object provide denser and courser time values depending of the rate of increase of the f(t)? For example,

[JAVA3D] Texture Mapping and Loaders

I made the changes that Suri suggested. He is correct that I didn't have the correct number of texture coordinates specified. However, this still did not correct the problem because there are no texture coordinates to change. I don't believe it is possible to add texture coordinates on the fly.

One quick and dirty way to "remove" objects is to simply translate them out of view. Does this offend any purists out there? Other that lack of elegance, are there any disadvantages to this? Alex === To unsubscribe, send

It strikes me that there is a lot of variability in the performance people are getting from different graphics cards on different platforms. I wonder how much of this is related to bus speeds, DMA and other hardware settings on the PC itself. Some of these results may be independent of the graph
