01 The single voxel
Built one voxel at a time.
A voxel is one cube of 3D space, the smallest thing you can build with. We think about scenes the same way: a model, then a material, then a light, each one there for a reason.
Most of the job is small decisions, and we fuss over every one of them. Nobody notices a good reflection on a bottle cap. Everybody notices a bad one.
