Unigine::Renderer Class
| Header: | #include <UnigineRender.h> |
A basic interface for setting a renderer state (changing rendering passes parameters): pass shader uniforms, set modelview and projection matrices, etc. This class is used for rendering custom nodes (for example, a node inherited from ObjectExtern).
