Hello Justin, I downloaded the code and tryed to run the CullingDemo sample. It seems that only j3d 1.3 beta is supported (using 1.2.1_03 gives errors during compilation) So is there a way to use the current "stable" version ?
I tryed to see crater_0513.bt and ratcliff_1k.bt files. For crater_0513.bt, I don't see the effect of your api on the rendering, perhaps there is a way to draw cells with differents colors ? (I don't take a look at the api yet) For ratcliff_1k.bt, nothing appears on the canvas ! Thanks for your help ! ________________________________________________ --- Justin Couch <[EMAIL PROTECTED]> wrote: > Enrique Dumas wrote: > > > I'd like to know how many FPS we can expect with a > > ROAM algotithm : I currently have a map which size > is > > 80 * 80 quads and my FPS on a PIII 800 with > geforce II > > is "only" 10-11 FPS (I am using j3d 1.2.1_03 on > win98) > > without moving the terrain > > Similar hardware, except it's a laptop running an > ATI Rage M3 - ie no > h/w T&L and pretty crap texturing.
