Java lwjgl shader program code#
Other than that I can't seem to figure out what the problem is.Īnyway, my question is how can the shader code be fixed to show a cube? I've searched for days trying to find the answer, so any help would be appreciated. I also turned off backface culling and made sure the znear and zfar was set correctly. I tried making the cube large, so if it was behind the camera, it would still be visible.
When I looked at the lwjglx debug output it didn't show any errors. So then I went on to add shaders and it all broke. It was using vbos and indicies and it did draw a colored cube like it should. The program worked fine until I added shaders. So I made a program to draw a simple cube with colors at each vertex.
