# Image Based Lighting

### Procedural synthesis of high-dynamic-range lighting environments for real-time visual realism.

**Generating procedural high-dynamic-range lighting environments in real time defines the physical integration mastery of SCORE XR.** By calculating Rayleigh-Mie atmospheric scattering and dynamic studio light placements directly on the GPU, Daniel Kuhnlein bypasses static cubemap limitations. This allows specular reflections and ambient diffuse parameters to adapt instantly to interactive day-night transits and light adjustments, enveloping virtual materials in seamless environment illumination.

**Real-Time Atmospheric Scattering**

Ray-marches Rayleigh and Mie scattering models on the GPU in real time, simulating Beer’s Law light attenuation and Henyey-Greenstein phase functions. This procedurally generates realistic skylines, dynamic sunsets, and atmospheric haze.

**Procedural Studio Synthesis**

Synthesizes virtual photography studios procedurally, giving creators slider control over ceiling area lights, surrounding spot color beams, and room bounce. Any adjustments instantly re-bake specular maps for metallic reflections.

**Soft Ambient Harmonization**

Smoothly integrates diffuse light into matte surfaces by extracting ambient color data from the environment. This ensures that objects reflect the correct atmospheric tones of the surrounding space, blending digital elements into the scene naturally without performance lag.

**By merging real-time studio configurations with physical sky models,** SCORE XR's image-based lighting pipeline eliminates static asset loading overhead. STD.DEV optimizes these GPU prefiltering passes to ensure instant startup times and high frame rates on standalone VR headsets.
