Constants

const RANDOM_PCG: Object

Uncorrelated pseudo random samples. Converges slowest but never shows structured artifacts.

const RANDOM_SOBOL: Object

Sobol low discrepancy samples, scrambled per pixel. Converges faster than RANDOM_PCG.

const RANDOM_BLUE_DITHER: Object

The same Sobol sequence for every pixel, offset by a blue noise dither so early frames read as smooth grain rather than clumped noise. The default.

const TRANSMISSIVE_BACKGROUND_ENVIRONMENT: number

Sample the environment map, so glass shows what is behind it.

const TRANSMISSIVE_BACKGROUND_OVERLAY: number

Set the opacity from the transmitted light intensity, tinted by the environment lighting.

const TRANSMISSIVE_BACKGROUND_TRANSPARENT: number

Attenuate the background by the transmitted light, so glass renders against transparency.
