2. MRPT Rendering Architecture

2.1 Two-module design: <tt>mrpt_viz</tt> and <tt>mrpt_opengl</tt>

In MRPT 3.0, the 3D scene graph and the OpenGL rendering code live in two separate modules:

Module

Namespace

Purpose

Abstract scene graph. No OpenGL/GPU dependencies. GPU rendering, shaders, textures, OpenGL calls.
