Betreff des Beitrags:  Faces Ocupying the same space
Iv noticed in RTCW maps that some faces overlap over faces, proberly the one thats ontop is a decal. My query is, is there anyway to make one dominant? Depending on where u look at them from, depends on which is dominant..... which looks stupid...

Just use glPolygonOffset before rendering the decals. This function offsets a polygon that drawn a the exact same place as another polygon.

Thx SOS :)

For anyone who doesn't know how to use the polygon offset(like i didn't) heres some simple code:

Code:
  1.  
  2. glEnable(GL_POLYGON_OFFSET_FILL);
  3.  


Code:
  1.  
  2. if Shader.polygonOffset then // If its a decal
  3. glPolygonOffset(0,0)
  4. else
  5. glPolygonOffset(1,1);
  6.  


Much simpler than i thought it would be.

Are you writing a game engine or something? After looking at the last few topics you stared, it sure seems like it.

Anyway, nice example of a decal.

Yes im trying to make a game engine, Its bassed on Q3MapView by Harry Paintner but heavily modifyed. Always wanted to mod Half-Life but could never find a copy of Visual C++ that was cheap(as in not above 100 pounds) or in a shop, so the next and better thing to do is make a game engine in the worlds best language.

Awesome!! Wish I could help, but my knowledge of GL is tiny. I hope to learn more and get some books soon. I'd be willing to give you ideas or test. :lol:

Best Wishes,
Robert
