Beginner Compute Shader Demo

Particles3D now supports an opt-in beginner path via learning_mode = Beginner.

In this mode, the operator uses a simplified compute flow intended for learning:

1. update particle state in a storage buffer (spawn + gravity + lifetime/bounds reset)
2. write per-instance transform/color data
3. render that instance buffer with the normal 3D renderer

Try graph: graphs/3d_particles_compute_beginner_demo.json

Shadow And Fog Examples

• graphs/3d_shadow_focus_demo.json: focused shadow-map demo (high-contrast floor + caster setup).
• graphs/3d_fog_fake_post_demo.json: fake atmospheric fog look using post-processing only.
• graphs/3d_fog_true_demo.json: true depth-based fog in Render3D via fog_* params.

Use fake fog for stylized screen-space haze. Use true fog for distance-aware atmospheric falloff.
