glEnable(GL_DEPTH_TEST) - nothing rendered

Question

In OpenGL, I display a simple model. When I enable the depth buffer,

glEnable(GL_CULL_FACE);
glEnable(GL_DEPTH_TEST);
glDepthMask(GL_TRUE);

If the above doesn't work, check your near plane in the gluPerspective, glFrustum, or glOrtho function. Depth buffering doesn't seem to work if it is set to 0.

I had tried almost everything but could not solve the overlapping issue. I had put the near value 0.0f. I changed it to 0.01f and the results now are how it needed to be.
