Shadow Mapping Problems
Hello...
I'm trying to implement hardware shadow mapping (ARB_shadow,ARB_depth_texture), but i have some problems.
Problem 1
Problem 2
Depth Buffer
As you can see from the screenshots the depth buffer is ok,and the projection works(shadows are in place).
In screenshot "Problem 2" i don't use PolygonOffset.When i use PolygonOffset, the Problem 2 disappeared,but "Problem 1" came up.
Is this a known problem??? How can i fix it? What do i forget to do ?
Thanks in advance.

Hmmm... Perhaps a z fighting issue? How about using glDepthFunc( GL_EQUAL )?
You have to remember that you''re unique, just like everybody else.

I think using GL_CLAMP_TO_EDGE (not sure if thats exactly right) for the shadow texture might solve the problem in the first image.
Ah, its GL_CLAMP. Take a look here (paulsprojects.net) for a pretty good shadow mapping tutorial.
