I'm trying to generate a 3d signed distance field for a origin centered ellipsoid. For a sphere this is pretty easy: x 2 + y 2 + z 2 − r. where r is the radius. I'm not sure what the best approach is for an ellipsoid. I expect plugging values into the implicit equation: f ( x, y, z) = x 2 a 2 + y 2 b 2 + z 2 c 2 − 1. bimmerlife.com
