GSoC 2017: Sculpting Tool Improvements - Emphasizing substance and material
In traditional sculpting the material is substantial to the work-flow. Adding or carving away material allows to define and create new shapes. In Blender the sculptor is not limited to a certain material but to an abstract web of vertices edges and faces. Most of the tools give a certain feeling of just pushing around vertices. The substance and volume is just a surface grid. The Goal is to give the sculptor better tools and improve the existing ones.
