As you can see texture is not mapped corectly, why? Im using this code for 2d mode:
w = 640;
h = 480;
	Gl.glTexCoord2f(0.0f, 1.0f); Gl.glVertex2f(0, 0);
	Gl.glTexCoord2f(0.0f, 0.0f); Gl.glVertex2f(0, h);
	Gl.glTexCoord2f(1.0f, 0.0f); Gl.glVertex2f(w, h);
	Gl.glTexCoord2f(1.0f, 1.0f); Gl.glVertex2f(w, 0);

I don't exactly see what's wrong (it's a spinning cube right?), but most probably the texturing coordinates have been flipped. So you coule try:

Gl.glTexCoord2f(0.0f, 0.0f); Gl.glVertex2f(0, 0);
Gl.glTexCoord2f(0.0f, 1.0f); Gl.glVertex2f(0, h);
Gl.glTexCoord2f(1.0f, 1.0f); Gl.glVertex2f(w, h);
Gl.glTexCoord2f(1.0f, 0.0f); Gl.glVertex2f(w, 0);

It's probably the loading code, but check to make sure it's not the actual texture. Many a coder has been tricked by trying to debug working code when the data is borked. [razz]

Ha ha, just found a problem!

I forgot to parse picture. I just loaded it with all header & other pixels directly to GL.
