Basically, the idea is that we want, for example, four levels of detail (LOD), with objects closest to the camera having the highest detail. But it takes time to generate models from their abstract description. So the solution is to generate the model at the lowest level of detail, and then fire off [...]

This planet has a slice taken out of it.
It uses a very simple ray-caster to compute a deformation of the sphere onto three planes. This has a benefit that we can take normal vectors from the planes, saving us the cost of computing normals for the entire deformed surface. It also has the [...]
