Diffuse materials too dark #58

Closed jalberse closed 4 months ago

jalberse commented 4 months ago

Diffuse materials appear to be too dark. Investigate why this is and fix it.

Apparent in dragon.pbrt test scene; but also in a simple cube test scene.

Fixed. Uniform hemisphere PDF was accidentally twice too big.
