iphone

I remember running into this problem when I started using OpenGL in OS X. Eventually I solved it, but I think that was just by using glut and c++ instead of Objective-C...

The lines of code I have in init for the ES1Renderer are as follows:

glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LEQUAL);

Then in the render method, I have this:

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

I assume I'm missing something specific to either the iPhone or ES. What other steps are required to enable the depth test?

Thanks
