    ImportanceSampledEnvironment

    +
    +
    +

    Manages a preprocessed HDR environment map (CDF textures, uniforms) and exposes +TSL helpers for BRDF-direction lookups and MIS importance sampling.

    +
    +
    +
    +

    Constructor

    +

    new ImportanceSampledEnvironment( importanceSampling : boolean )

    +
    + + + + + + + +
    + importanceSampling + +

    When true, builds luminance CDF tables and enables MIS env sampling.

    +

    Default is false.

    .sampleEnvironmentMIS( params : Object ) : Node.<vec3>

    +
    +
    +

    Environment reflection for a screen-space miss, estimated with multiple importance +sampling (MIS) between the BRDF / reflected-ray direction and the env-luminance CDF +direction. Both techniques use consistent solid-angle PDFs (D·G1(N·V)/(4·N·V)), so +the power heuristic is unbiased. Adapted from three-gpu-pathtracer.

    RecurrentDenoiseNode

    +
    +
    +

    Post processing node for denoising temporally-accumulated screen-space effects +such as SSGI (ambient occlusion / indirect diffuse) and SSR (specular reflections).

    +

    The denoising kernel is selected at construction time via mode: +'diffuse' (SSGI) or 'specular' (SSR). The kernel uses a fixed 8-sample Vogel disk.

    +
    +
    +

    Import

    +

    RecurrentDenoiseNode is an addon, and must be imported explicitly, see Installation#Addons.

    +
    +
    +

    .alphaSource : DenoiseAlphaSource

    +
    +

    Which channel of the raw texture drives alpha-based edge stopping. +'raylength' — alpha encodes SSR ray length; 'ao' — alpha encodes AO factor; +'none' — skip alpha-based edge stopping.

    +

    Default is 'raylength'.

    +
    +
    +
    +

    .mode : DenoiseMode

    +
    +

    Denoising kernel type.

    TemporalReprojectNode

    +
    +
    +

    Temporal reprojection pass for denoising screen-space effects (SSGI, SSR, etc.).

    +

    Both modes share geometrically-weighted 4-tap bilinear history sampling and YCoCg variance clipping. +Surface velocity reprojection is always sampled first. Specular mode then blends in +hit-point parallax history on top of that surface result. +Diffuse mode applies velocity-field divergence to detect surface stretching.

    +

    Unlike jitter-based TAA/TAAU, this node does not apply camera sub-pixel jitter — it only +reprojects and accumulates history using motion vectors.
