public sealed class ScreenProbeUpsampleRenderer

Per-pixel irradiance out of the resolved screen probes — doc 19 § L3's upsample, first form.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

The screen-space sibling of IndirectDiffuseRenderer. That one asks a world-space field what arrives at a position; this one asks the probe lattice what arrives at a pixel, out of the four planes ScreenProbeResolve wrote. What comes out is the same kind of buffer: irradiance over π, for a shading pass to multiply by albedo.

Bilinear only, deliberately. The bilateral half — weights that also respect depth and normal edges — is the denoiser's opening move and lands with it, against frames this version is the baseline for.

Usually a child of ScreenProbeGatherRenderer, which places the probes, runs the trace and resolve dispatches, and publishes the planes this reads. Standing alone it draws whatever planes the frame imports under Planes — which is what the image tests do, so "the node schedules wrongly" and "the pass draws wrongly" stay separable.

Fields and properties (9)

public required string Depth
The depth that says which pixels show the sky.
public required string Normals
The normals the probes are asked about.
public required ScreenProbeTexture Probes
The probes to upsample — the mirror whose planes the resolve wrote.
public required string[] Planes
The four planes' graph names, in packing order — imported by whoever owns the frame.
public float Intensity
A multiplier on the result, for Intensity's reasons.
public string? SurfacePlane
The probes' surface plane's graph name, for the bilateral taps. Null binds a stand-in.
public string? NormalPlane
The probes' normal plane's graph name. Null binds a stand-in.
public float PlaneTolerance
How far off a probe's plane a pixel may stand and still read it, in world units.
public Matrix4x4 InverseViewProjection
What turns a pixel's depth back into the world the probes stand in.
