Softbox

Little time, little time… therefore only little progress: Added what people call an “infinite area light”. This is a light source that illuminates the scene evenly from all directions. Photographers approximate this using a Softbox and that’s how I call it, too.

There are 27 speheres in this scene, and the lack of any acceleration structure is why rendering took 28 minutes for this one (again at 100 samples per pixel).
