Directional Lights

Orthographic cascaded shadows in SCORE XR bake shadows using an orthographic projection matrix to prevent perspective distortion and divide the camera frustum into cascades to maintain shadow crispness across vast distances.

The Angular Sun Disc Specification models the sun as a circular area light with configurable angular sizes, generating soft specular highlights and natural daylight reflections.

Dynamic Solar Altitude Tracking allows the solar vector to be updated dynamically based on real-world time or user inputs, enabling the simulation of realistic day-night cycles by morphing shadow lengths and sky colors.

The mathematical sun model casts consistent, parallel shadows that establish a cohesive spatial frame across large-scale WebXR environments, grounding expansive open-world coordinates in a unified atmospheric time of day.

The sun disc in SCORE XR can be configured with angular sizes ranging between 0.25° and 20.0°.

SCORE XR establishes consistent shadows and specular highlights across expansive outdoor environments by using a directional light model that illuminates all scene objects uniformly from a single, infinitely distant direction.

The core principle behind SCORE XR's large-scale atmospheric rendering is simulating infinite parallel light rays to replicate natural sunlight.

SCORE XR prevents perspective distortion in its shadow rendering by baking shadows using an orthographic projection matrix.
