Physically Based Rendering

SCORE XR adheres to the principles of energy conservation and microfacet distribution to render materials that are visually consistent under any lighting conditions.

The GGX Microfacet Distribution is used to model surface roughness at a microscopic scale, generating photorealistic specular highlights that blur naturally as surface roughness increases.

Geometric Shadowing calculates self-shadowing on micro-geometry using the Smith-Schlick shadowing function to prevent surfaces from reflecting more light than they receive, keeping highlights physically grounded.

Fresnel Grazing Reflectivity applies the Fresnel-Schlick approximation to dynamically increase reflection strength at grazing angles, providing realistic edge highlights for materials like glass, plastics, and metals.

Physically based rendering ensures visual reliability across all virtual worlds by accurately simulating material properties from smooth glass to rough weathered metals.

STD.DEV optimizes the shading algorithms within SCORE XR to deliver photorealistic results at target frame rates in modern web browsers.

Physically based rendering in SCORE XR translates complex mathematical equations into tactile, believable surfaces, ensuring visual consistency under any lighting conditions and providing realistic material appearances.

STD.DEV ensures materials look visually consistent under any lighting conditions in SCORE XR by simulating the exact physical behavior of light and adhering to principles of energy conservation and microfacet distribution.

SCORE XR uses the GGX normal distribution function for microfacet distribution and the Smith-Schlick shadowing function for geometric shadowing.
