Detailed Description

Rendering-only DisplayDevice subclass that performs core OpenGL rendering operations to generate molecular graphics from VMDDisplayList tokens.

OpenGLDisplayDevice is not a complete DisplayDevice subclass definition. Another subclass must provide routines to open windows, reshape, clear, set perspective, etc. This object only contains the low-level OpenGL code to render VMDDisplayList DispCmd tokens to create molecular graphics. OpenGLRenderer renders drawing commands into a framebuffer and (possibly in an on-screen window) managed by one of the other DisplayDevice subclasses, e.g., OpenGLDisplayDevice, FltkDisplayDevice, OpenGLPbufferDisplayDevice, etc.
