Struct three_d::context::GLContext

pub struct GLContext { /* fields omitted */ }

Contains the graphics API for almost direct calls to OpenGL/WebGL. Used internally in the higher level features and can safely be ignored unless you want more control.

Calls to this API can be combined with higher level features.
