Thanks!
Last night I tried similar code that I got from another member, with some
mods. Looks
similar to this one though. I am getting about 10 FPS - way low for the
hardware I just installed -
DELL 2GHz / 1GB RAM / GeForce 4600 128 MB ?? The CPU is running at 50-60%
with or without
FPS behavior. But as I added FPS behavior ( I also have another more
elaborate behavior for
picking ) it shoots up to 100% - but the speed of the rotations (and thus I
believe the FPS itself) is
not visibly affected.
I upgraded from the old system - DELL 500 MHz / 256 RAM with old graphics
card where I was getting
one jerky move every 2-3 seconds - so it seems like a good 10-20x
improvement in speed. Current rotation
is real-time, but not smooth.
After searching through the old emails and FAQs I found the
"java -Dj3d.debug=true" which I added to the
command line - but I still do not get any info on the hardware/software
acceleration from the card. Is there a
sure way to tell what the card is doing ? My scene has some 5000 quads (not
triangles) with indexed geometry,
no textures. Is there a issue with card not supporting quads, but only
triangles in hardware acceleration mode ?? I
think I read that somewhere that it could be an issue ...
I am also getting strange white line in the middle of the scene - which I
did not have on the old machine.
Thanks,
Zoran
