glPushAttrib(GL_VIEWPORT_BIT);
glPopAttrib();

I'm trying to get some basic OpenGL-ES with Shaders to run on the iPhone, based on some examples.
For some reason my projection matrix refuses to result in something on the screen. It feels like a clipping plane is set very near but that contradicts with the values I supply. If I render the same…

I think I have my wires crossed on this, it should be quite easy.
I have a projection matrix from world coordinates to image coordinates (4D homogeneous to 3D homgeneous), and therefore I also have the inverse projection matrix from image coordinates to world "rays".
I want to project points of…
