Hi everyone. I just wanted you to see my new demo of the algos I have been talking about on this very excellent board…
Have a look at www.tooltech-software.com and you will find a demo of the shadow system for automatic usage in scene graphs. The demo uses the MAC algo for shadow volume capping as well as it is prepared to use shadow image + displacement mapping for generation of the volumes…
I added the source code to the demo as many people wanted to see the “automatic” stuff. The new dist also includes some improved interconnectivity calculations wich improves the speed.
I have now updated the demo to do a better performance benchmark. If anyone is interested they could run the program and tell me what framerates you get and what kind of HW you have.
I’m running a Duron 1100 & GF4-4200 (not o/c)
In the default window I get 130-140 fps.
In maximised window (1152x864) I get 85 fps… Same as my monitors refresh, ie: might be the limiting factor.
I have uploaded a new softshadow demo version. I have also released the new libs used in that demo. The new libs now optimise the shadow volumes when they become static more than 10 frames so for static volumes or in scenes where the light doesn’t move the speed increase is 200 %
The case when the light moves all the time is also optimised but still rather slow because of fillrate and bandwidth limitations.
Feel fre to play with the libs and run the demos on various models. I need feedback
