Expand description

WT.2 — a full-screen tint: every resolved pixel lerps toward color by strength. See FrameParams::tint for where in the pipeline it applies.

The blend is integer: strength quantizes to 8 bits and each channel computes (c·(255−s₈) + t·s₈ + 127) / 255 — the identical arithmetic on both backends, so tinted frames are bit-exact across CPU and GPU by construction (a float lerp + round pair provably drifts ±1 from WGSL mix + pack4x8unorm on ~2.5% of byte pairs, and driver float contraction is out of our control). Strengths below 1/510 quantize to 0 = off.

Known seam: overlays (SceneRenderer::draw_lines / SceneRenderer::draw_images) rasterise before the resolve on the CPU backend (they are graded with the scene) but after it on the GPU (drawn over the grade at full brightness).

Fields§

§color: Rgb

Target colour, packed 0x00RRGGBB like every facade colour.

§strength: f32

Lerp factor, clamped to 0..=1 at use. 0.0 is an identity (byte-identical to None); 1.0 paints the frame flat.
