Hey, good job !

Regarding the "curious result" with paraboloid and HDR files, I suspect the code we use to handle this file format in the player applies some sort of gamma correction, which is almost like taking the square root of the luminosity (typically taking it to the power 1/2.2, whereas the square root is 1/2). Since the formula for the paraboloid is 1-x²-y² and the formula for the half-sphere is just the square root of that, that may explain what you are observing.
