Detailed Description

The representation of an OpenGL rendering context, state-machine or pipeline.

This class is a wrapper around OpenGLs GLXContext.

Any thread that wishes to call OpenGL rendering primitives, must first be bound to a rendering context and to a drawable such as a window. This is done by instantiating the Bind class.

New rendering contexts are created by calling Visual::createContext.

virtual bool Archon::Display::Context::isDirect (   )  [pure virtual]

Tell whether direct rendering is enabled for this context. Direct rendering contexts offers better performance but generally works only on a display of the local host. Implemented in Archon::Display::ContextX11.
