This is an implementation of paper None-linear sphere tracing for rendering deformed signed distance fields.
Instead of creating polygon mesh that consists of vertices, the surface is defined by implicit function (signed distance function).
The surface which is deformed in real time is rendered using Non-linear sphere tracing, a method that was presented by this paper.

- This code is not reviewed nor confirmed. There could be faults in implementation, and it has some skipped parts.
