The problem is in the quadratic you set up to solve, which is incorrect. You've got something wrong with your shading - most things in the rendered scene are turning out completely white. It's also taking a VERY long time to render. You implemented Jiggle, but you misunderstood the supersampling part -- supersampling without jiggle has no random component - it's simply sampling over a regular subgrid. --------------------------------------------
