Polar Coord Cubemap

Recommended Posts

I am trying to make a cubemap that will map a vector into polar coordinates when I look up the values, but the problem is that it gets distorted since the cube map sides get distorted when covering a sphere. How can I calculate polar coordinates from a cubemap while accounting for this distortion?

Are you sure you're generating the cube map texture correctly? Obviously you'll never get a perfect result with a cube map, but you should end up with something pretty nice looking with bilinear interpolation.
