    Interface LightGPUData

    Represents the binary GPU-ready memory alignment structure for individual lights. Conforms precisely with the WGSL standard layout struct declared within the default shader.

    interface LightGPUData {
        b: number;
        dirX?: number;
        dirY?: number;
        dirZ?: number;
        g: number;
        innerAngleCos?: number;
        intensity: number;
        outerAngleCos?: number;
        r: number;
        range?: number;
        typeFlag: number;
        x: number;
        y: number;
