- Post-processing enhances 3D scenes with atmospheric and lighting effects efficiently.
- Volumetric Lighting creates realistic beams of light, adding depth and atmosphere to scenes.
- Coordinate system transformations are crucial for converting between screen space and world space.
- Raymarching is used to simulate light propagation through a volume, creating dynamic lighting effects.
- Shadow mapping improves realism by accounting for light occlusion by objects in the scene.
- Performance optimizations include blue noise dithering to reduce artifacts and improve efficiency.
- Light scattering and phase functions enhance the realism of volumetric lighting.
- Applications include creating moody atmospheric scenes and enhancing space-themed visuals.
- Challenges include handling multiple light sources and omnidirectional shadow casting.
- Future directions may explore global illumination and ambient occlusion for more advanced lighting effects.
