Computer graphics uses flat triangles to approximate smooth surfaces, but if you're willing to allow triangles to bend a bit, then you can build any surface by gluing enough of them together.

Hence, I generated 5*6=30 different days in different directions in a homegoneous way. My results are neither too bad, nor good enough. I think that some triangles do not have a consistent sdf value.

Triangle Mesh Filler Triangle Mesh Filler is a GUI app made with egui for "Computer Graphics 1" course. Its main goal is to simulate a light source going over a user-defined Bezier Surface. The user ...

That's where advances in neural radiance fields can be a boon. In this case, NVIDIA claims a single Tensor Core GPU can leverage its 3D MoMa tool to generate triangle mesh models in only an hour.
