The Demo runs on Windows, is written in C and uses OpenGL for all its graphics. You should own a Pentium III 500 or better CPU, a Riva TNT-class graphic-board and a soundcard. The demo defaults to a resolution of 800x600 pixels in current colordepth (16 or 32bit).
On Windows NT 4.0 you can just start the demo , on Win9x you have to switch off the “always on top”-checkbox of the taskbar. (Win2000 is untested at this time)
I tried it out on my machine (Dell PIII dual
600 mhz, Matrox G400, win2K) and it had
serious visual artifacts.When I quit
the demo all the text on my screen in every
window was scrambled. I had to reboot to correct the problem.
Maybe it’s just my configuration. Matox’s drivers don’t seem to be that great.
Tried your demo on p3-700/GeForce DDR and it ran around 1 FPS. Must be a w2k issue i think as this other fellow seemed to have the same problems as I. Running w2k professional.
i tries -window -nosound options. still no better. Although i didnt get the visual artifacts just slow performance.
About the same results for me… a new animation every 1-2 seconds… It looks like it have fall back to software rendering to me… by some reason. tried at 16 and 32 bit desktop, same result.
I had the opportunity to run the demo myself on a GeForce and it did only software-rendering. I don’t know, why, but I think I shold post my initialisaton-code. Perhaps you have any idea. Sorry.
I think ijl10.dll is a standard lib of routines that goes with the “OpenGL Challenge” skeleton app. You should be able to find the Challenge homepage from a link on the main site; any of the entry downloads should have the lib in.
I thought about it yesterday evening : when I first received my GeForce, I had GL_POLYGON_SMOOTH enabled in one of my programs and it made the card SLLLLOOOOOOWWWWWWWWWW !
The new version of Opalis is released now. I fixed a “bug” (more a workaround) which prevents GeForce graphic-cards to use hardware acceleration.
Tip: don’t use glHint( GL_POLYGON_SMOOTH_HINT, GL_NICEST ) if your demo should run on a GeForce. It runs only with GL_POLYGON_SMOOTH_HINT, GL_DONT_CARE )!!
Thank you AndersO and Eric (and of course all the others).
