Detailed Description

Base DrawContext class.

DrawContext derives several sub-classes with API specific functionality (GL, D3D11, ...).

Current specificiation GPU hardware tessellation limitations require transition patches to be split-up into several triangular bi-cubic sub-patches. DrawContext processes FarPatchArrays from Far::PatchTables and generates the additional sets of sub-patches.

Contexts interface the serialized topological data pertaining to the geometric primitives with the capabilities of the selected discrete compute device.
