    Properties

    initialUniforms: object

    The initial values of the shader uniforms.

    speed: number = 1

    The speed multiplier applied to animation. 0 stops animation.

    COMPUTE_MASK: string = ...

    Compute the weather masking value.

    FRAGMENT_HEADER: string = ...

    Compute the weather masking value.

    Accessors

    • set scale(scale: number | { x: number; y: number }): void
