Overview
Process of allocating and configuring the abstract scene representation, camera, and visualization options required for rendering a MuJoCo simulation.
Description
Visualization Initialization prepares the non-GPU data structures needed before any rendering can occur. This involves three components: the mjvScene (abstract scene with geometry buffers for geoms, flexes, and skins), the mjvCamera (viewpoint specification), and the mjvOption (visualization flags controlling what is displayed). The scene must be sized to accommodate the maximum number of geometries that will be rendered simultaneously.
Usage
Use this principle after loading a model and before any rendering calls. The scene allocation depends on the model (for flex and skin data), so the model must be loaded first.
Theoretical Basis
The visualization pipeline separates abstract scene construction from GPU rendering:
# Abstract pipeline (not real code)
scene = allocate_scene(model, max_geoms) # CPU buffers
camera = default_camera() # viewpoint
options = default_options() # display flags
# ... later: update_scene() fills scene from simulation state
# ... later: render() sends scene to GPU
This separation allows the same scene to be rendered to different targets (on-screen, offscreen) and allows scene updates without GPU interaction.
