[JAVA3D] Chellenge To Java3D Engineers ;)

Will you all join me in asking a Java3D engineer(s) to demonstrate with code how to write a picking behaviour that only wakes up on left click whist a character key "A-Z" is depressed. All the examples with Java3D are with Alt or Control but these are useless for big applications except for zoom

Re: [JAVA3D] Z-BUFFER PROBLEM????

Yep it's the Z buffer tearing problem again. Have a look at the ViewNavigationBehavior mod I sent to the list under the title "Test program (fwd) for Grafic card question" it has a solution to this (or a least Desiree's similar) problem. Hopefully it will work for you (maybe with some tweaking).

I don't think that should be too hard ( just guessing ). On one of our projects, we are forcing keyboard focus onto our canvas3d when we get mouse focus, and then we watch for keyboard presses for navigation. I would set up for AWT keyboard and mouse clicks, and just remember when the letters yo

Re: [JAVA3D] Z-BUFFER PROBLEM????

Yep, laying down roads over terrain is a nasty problem. This is especially true if you are using a different "road" geometry. You need to create co-planar geometry which can be done a variety of ways. One way is to build your geometry for the road using the same heightmap source as the terrain
