# Defered Shading

### Decoupled light and geometry processing for enhanced rendering speed and unconstrained lighting complexity.

> Performante Berechnung von Licht und Schatten

**Decoupling scene geometry calculations from lighting evaluation defines the massive scene scalability of SCORE XR.** By storing positions, normals, and material parameters in a multi-target G-Buffer first, the engine evaluates complex illumination in a single screen-space pass. This deferred rendering pipeline allows virtual environments to support hundreds of dynamic, shadow-casting light sources simultaneously.

**G-Buffer Partitioning**

Caches surface albedo, normals, roughness, and depth values to separate screen-space textures in a single geometry pass, minimizing costly vertex calculations during lighting passes.

**Conical & Spherical Light Volumes**

Restricts lighting calculations to the exact screen-space bounds of each point and spot light volume, completely bypassing calculations for pixels outside the light's reach.

**Unconstrained Light Scales**

Eliminates the complexity bottleneck of forward rendering, allowing hundreds of dynamic light sources to shine at once without causing frame drops on standard GPUs.

**From glowing sci-fi corridors to dense urban nightscapes,** deferred shading unleashes lighting complexity. STD.DEV fine-tunes these buffer layouts to achieve high performance on both mobile and desktop web browsers.
