Z-Fighting anyone?
jj Wed Nov 19, 2008 10:39 pm
Hi,
I am having an issue where my solid cylinder object appears to be "see-through". There's little specs of inside material showing, when it should be a solid cylinder "shell".
From what I can tell this issue is called z-fighting, and happens in OpenGL.
Has anyone experienced this when rendering sio2 objects? Are there any solutions?
Thanks in advance

- Code:
// Enable polygon offset to avoid zfighting
glEnable( GL_POLYGON_OFFSET_FILL );
// If you are using the simulator theses values
// will do.
glPolygonOffset( -2.0f, 2.0f );
// Setup the polygon offset, on the device polygon
// offset require extreme value in order to work
// correctly. Try setting the optimal combination
// proper to your application. The following value
// will work but are not optimized...
//glPolygonOffset( -10.0f, -10.0f );
...
...
// Disable polygon offset
glDisable( GL_POLYGON_OFFSET_FILL );

You should also check that your model's normals are correct.
