From 894603b1d27ad8d1d42f4c2e06fc476ba8963d28 Mon Sep 17 00:00:00 2001 From: qianiaoo Date: Wed, 19 Aug 2026 09:50:58 +0800 Subject: [PATCH] feat(draw): a POLY op, so rotated solid geometry carries coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `TRI` has no coverage field, so a rotated solid box resolves to two grey levels at any resolution — `emit_box` -> Sutherland-Hodgman -> `emit_tri` rounds every vertex to an integer pixel and there is nowhere to put a partial one. Recorded at `draw.rs:10-18` as a v1 degradation; what was missing was the price. `POLY` (opcode 10, `3 + N` words) carries the whole clipped convex polygon and one flat colour, so coverage is computed over the shape rather than per triangle. Per-triangle coverage is the wrong fix and the guard says so: two sequential blends are not one blend, and the shared diagonal of a rotated box keeps 68 interior partial pixels. Over the polygon it keeps none. It is not slower. `poly()` solves each scanline for the fully-interior x-range, fills it as one run and samples 4x4 only at the ends — O(perimeter), not O(area) — against a `tri` that evaluated three `orient()` calls for every pixel of the bounding box with no incremental stepping. Measured at 0.99x on a standalone bench and 22% faster end to end on eight rotated bars at 1080p. The inner loop stays integer: edge functions in 4*F fixed point, quarter-pixel offsets as +/-1 and +/-3, `div_euclid` for the span solve. No float enters it, so the frame-hash contract carries over. Hardware backends without per-pixel coverage decode `POLY` to a triangle fan — today's binary fill, byte-identical output. `Fill::Grad` keeps its TRI fan.
