Patrick:
I have been contemplating using Java 3D for the same purpose for my thesis.
My simulator is not complete yet. I have a long way to go yet because I
just finished the planning stages and have begun the implementation. The
floating-point fire spread calculations are written in C, but I hope to use
the JNI (Java Native Interface) to glue my code to the Swing GUI toolkit.
My gut feeling is that the 3D probably won't work with Java because of the
performance issues. Have you checked out VisAD (similar to Vis5D)
http://www.ssec.wisc.edu/~billh/visad.html
HTH.
Send me email with what you find out about how reasonable it is.

Subject: [JAVA3D] DEM with IndexedTriangleStripArray
> shello
>
> First I have to say that I am more or less a beginner in programming
> Java3D. That is the reason why a have some basic questions.
>
>
> I'd like to develop a tool for the visualization of wildfire (spr ead) in
> a
> 3D environment. Till now I have visualized a small part of the swiss alps
> with the IndexedTriangleStripArray Class.
>
> So my questions are:
>
> 1. How can I define the color or the transparency of a single triangle.
> The problem is that I have some "nodata" values (-9999) in the DEM Grid.
> And triangles with nodata-values should not be seen in the model.
>
> 2. As a next step I want to visualize the firespread. One solution could
> be, that after a certain time the color-value of a single triangle (or
> cell) would be change. Has anybody made some experience with spread
> animation or could have an idea.

> Thanks....
