Your videos are much more better, intuitive and easier to understand than the posts on Patreon. I wish every post would have a corresponding video, then i will return to patreon
Thanks. The Patreon posts are generally the scripts for future videos. Posts are much quicker to write and people make useful comments on the posts which help me improve them for the videos. A lot of work and resources go into the videos so I cannot produce them as fast as the posts.
If you mean, can the Fourier Transform model a 3D sphere, then yes it can. See: chalmers.instructure.com/courses/10248/files/719670/. Presumably adding features to that ball like mountains and valleys should be possible, although I have no idea how to do it myself.
