Unsolved Problems in the Field of Procedural Shaders and Procedural Terrain

In lieu of the increasing amount of work being done in the field of computer graphics, game development and procedural generation, this paper aims to provide a bird sight view of the evolution in the field of shader research. There are several topics that demand further research and analysis such as performant replacements for water ecosystems by computing noise, advanced techniques that are supported by the increase in hardware capabilities and the lack of a structured methodology to create procedurally generated textures. This paper will catalogue and review the problems that require further research throughout the various research papers written, as well as discuss the open challenges that remain in the field.
