Projects / nervous conduction simulator
« on: February 28, 2006, 05:38:54 am »
I'm trying to make a dynamic display of animal muscle conducting nervous signals.  The setup is a grid of over 1000 color-coded tissue squares (maybe 10 by 10 pixels each) with different conduction properties.  You can stimulate different areas and view a glow (depolarization) that spreads outwards through the tissue at different rates.

1)  I would like the glow, simulated by shifting the pixel colors at each grid square, to be hardware accelerated yet also run in a Swing environment.  Is it possible to use jPCT for this purpose?  I would like to avoid Java 2D unless you'd get just as good performance.

2)  What renderer and functions would I use (FrameBuffer blits?)  I'm still not clear what framebuffer limitations AWT GL Canvas has.  All I want to do is change pixel RGBs very fast.

3)  Would a hardware accelerated option work on Mac OS X as well?


Support / Software reflections, projected shadows, etc.

I found another 3D engine that uses software rendering (Anfy3D) that can do  reflections, projected shadows, and cool additive blending (for fire particles).  But it is not a free engine nor is it tailored to creating games like jPCT.  Perhaps it would be possible to incorporate these features into jPCT?
Then click "Watch another version" to see some more effects.

Support / lightmaps

Is there a way to have multiple UV coordinates for objects such that you can tile a brick texture, but also stretch out a single light map on that surface?  How would you recommend doing lightmaps?  Thanks.

Feedback / Volume shadows

Are volume/stencil shadows feasible for jPCT?
