    Type Alias LightUniforms

    The lights of a frame, flattened into the arrays the built-in light uniforms are uploaded from. Everything is in view space, so a shader can combine it with the vPosition and vNormal the built-in vertex shader produces, and every colour is premultiplied by the light's intensity.

    Directional lights are given by the direction they shine in (the node's -Z axis), so the vector towards the light, L in the lighting equations, is its negation.

    type LightUniforms = {
        ambientLightColor: number[];
        directionalLightColors: number[];
        directionalLightCount: number;
        directionalLightDirections: number[];
        pointLightColors: number[];
        pointLightCount: number;
        pointLightPositions: number[];
        pointLightRanges: number[];
    }
