Clipping problem???

Recommended Posts

Hello,

I've got stuck at rendering a terrain patch in isometric style... :-(
The landscape is produced by setting an isometric transformation matrix which transforms the map coordinates - with x being the map-x axis (range 0 - 50), y being the y-Angle (height of a terrain point; range 0-10), and z neing the map-y axis (range 0-50). On a TNT 2, everything shows up normally and the triangles are transformed correctly; on a GF 2 the triangles seem to be clipped in the z Direction, and I only see a pixel row as relief:
http://www.geocities.com/multum.geo/clipscreen.tif. I have tried restricting z coordinates to range from 0.0 to 1.0, and have also turned off all clipping. Has anybody some idea what else I could check? As said, the problem only appears on a GF 2, not on a TNT2, so I would not expect my transformation matrices to be wrong. If it helps, I can also post some source code here...

Thanks a lot [edited by - asd_de on August 18, 2002 12:20:09 PM]
