   Roam 2 Problem
  Hey,currently I try to develop a terrain following the Roam 2 Algorithm as described in Trent Polacks book "Focus on 3D Terrain Programming". So far I have the system up and running except there seems to be a problem with the vertices. As you can see on the screenshot it seems that old triangles aren't deleted correctly but I couldn't verify that in the code. It seems to be everything ok. Has maybe anyone experienced similar problems or does anyone have a suggestion what could be the problem? I am a little at a loss!Thanks a lot!Nikosch
