I am trying to get a skybox rendered correctly in my first person shooter game. I have the skybox cube rendering using GL_TEXTURE_CUBE_MAP. I author the cube with extents of -1 and 1 along X,Y and Z.

However, I can't wrap my head around the camera transformations that I need to apply to get it right. My render loop looks something like this:

• mp_Camera->ApplyTransform() :: Takes the current player transformation and inverts it and pushes that on the modelview stack.
• Draw GameObjects
• Draw Skybox

DrawSkybox does the following:

glEnable(GL_TEXTURE_CUBE_MAP);
glDepthMask(GL_FALSE);

// draw the cube here with extents

glDisable(GL_TEXTURE_CUBE_MAP);
glDepthMask(GL_TRUE);

EDIT: I forgot to mention: It looks like a small cube with unit extents. Also, I can strafe in/out of the cube. Screenshot:
