Hwllo,
have you tried if the following code works?
float winz;
Gl.glReadPixels(mouse_pos.X, mouse_pos.Y, 1, 1, Gl.GL_DEPTH_COMPONENT,
Gl.GL_FLOAT, out winz);
or
float[] winz = new float[1];
Gl.glReadPixels(mouse_pos.X, mouse_pos.Y, 1, 1, Gl.GL_DEPTH_COMPONENT,
Gl.GL_FLOAT, winz);
Is this Tao 1.3 or Tao 2.0? If it is 1.3, try updating to Tao 2.0 (or use
the beta posted at the forums:
http://www.taoframework.com/forum/development/developertalk/231), some
bugs have been fixed there.
Last, on what platform are you running the code? Mono (1.0/1.2)/.Net (1.1
or higher?), Windows/Linux, x86/x64?
Best regards,
