Hello Everyone, a while back I did TheCodingUniverse's tutorial #24 and #25 to load in a .obj file and render the mesh and then later add lighting to it. After completing these tutorials I really wanted to figure out how to texture the mesh that I was rendering. So I went looking for tutorials with little luck. I eventually just tinkered with the .obj file and then modified the code for tutorial #24 to handle the Texture Coordinates and the UV Indices(not sure if thats correct name). Now that I have it somewhat working, I am still having an issue with rendering.

Here is a video of what I have so far, the video shows rendering the object as a mesh and then with the texture mapped onto it.

Here is the code

Just looking for some help on how to fix this issue.

You need to enable depth testing.

Change Display.create(); to Display.create(new PixelFormat(24, 0, 24, 0, 0)); //Requests a back buffer with a z-buffer.

Add glEnable(GL_DEPTH_TEST); just before you start rendering the scene.

Your glClear() already clears your depth buffer (which you didn't have before).

Thanks so much, that worked like a charm. Now that you mention it I do remember reading that somewhere.
Thanks again.
