Parallax Occlusion Mapping OpenGL

I implemented parallax occlusion mapping / relief mapping in my C++ OpenGL engine sandbox to give a fake sense of 3d to textures with a height offset.

I generated a procedural night sky w/transparent quads w/a radial fall off in my c++ rendering framework.

The algorithm is pretty simple and goes something like:

// the trick is to sample an interesting distribution ;)
pts = sampleRange(xMagnitude, yMagnitude, zMagnitude, numStars)
render(pts)
captureSkybox()

// typical main loop here
while (true) {
 drawSkybox()
 drawScene()
 ...
}
