From 712324ca4d62288148b50f28758be7925cacc614 Mon Sep 17 00:00:00 2001 From: Fernando Date: Mon, 20 Apr 2026 20:53:33 -0400 Subject: [PATCH 01/10] feat(bevel): add segments and profile parameters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit HalfEdgeMesh::bevelEdges grows two new optional parameters: - segments (int, default 1): subdivides the chamfer strip into N steps, inserting segments-1 intermediate vertices on each endpoint between v1a/v1b and v2a/v2b. The strip is emitted as 2*N triangles instead of the original 2 — winding is preserved when N==1 so existing fixtures pass unchanged. - profile (float in [0, 1], default 0.5): profile-curve shape. - 0.5 = flat (linear interpolation, identical to single-segment). - >0.5 = convex (intermediates bulge toward where the original edge was — fillet-like rounded chamfer). - <0.5 = concave: currently CLAMPED TO FLAT. Inward bulge trips a Phase-7 winding edge case in the corner-cap emission that produces inverted triangles even for tiny inward shifts. The flat/convex half of the parameter range covers Blender's typical use; concave is gated behind that bug fix in a follow-up. Bulge magnitude is capped at 0.5*width at the chord midpoint, applied along the (chord, v) plane perpendicular to the chord. Wires through EditModeController: - BevelSession gains segments + profile fields. - updateBevelSegments(int) and updateBevelProfile(float) re-apply the bevel on the snapshot mesh, mirroring updateBevelWidth. QML inspector grows a Bevel section that's only visible while a bevel session is active: a SpinBox for segments (1..16) and a Slider for profile (0..1, snap 0.05) with a help line explaining the value range. 6 new unit tests covering segments=1/2/3/4 (flat), segments=4 convex, and a profile-shifts-position assertion. 88 HalfEdge/EditMode tests pass overall.

The post-pass had a hard `if (loop.size() > 8) continue;` cap meant to skip bizarrely large (probably non-simple) loops. But a multi- segment bevel's corner-cap loop is legitimately 2*(segments+1) verts: one per chain step on each side. segments=8 lands at 18, immediately over the cap. The fix raises the cap to 64 — generous for any reasonable bevel, still a finite guard against runaway walker output. Symptom: a visible HOLE on the front + back of a cube edge beveled with 8+ segments. 2) concave profile produced inverted fill triangles. The fill-winding decision was geometry-first: compute the face normal from loop[0..2], compare to the neighbor-averaged refNormal, flip if they oppose. That's fine when the fill surface is roughly flat, but breaks when the loop vertices sit on a curved profile — concave profiles pull the midpoint inward enough that the computed loop-triangle normal actually points the OPPOSITE direction from the surrounding surface. Result: same topology, reversed winding → non-manifold. Swap to topology-first: use the `flipScore vs noFlipScore` direction that partners the most existing directed boundary edges. Only fall back to the geometric refNormal check when those scores are exactly tied (ambiguous topology, only geometry can decide). This is robust against any profile curvature and is also the right default on submesh-seam cracks where the fill's face normal isn't well defined. With both fixes, profile now runs full [0, 1] range at any segment count. The safeProfile clamp + concave-disabled comments are removed from HalfEdgeMesh.h/cpp, EditModeController.h, and the QML help string. New tests: - BevelSegments8/12/16 flat (cover the loop-size cap). - BevelSegments4/8 concave (cover the winding bug). - BevelProfileShiftsIntermediateVertexPosition now asserts BOTH convex (closer to corner) AND concave (farther from corner). 93 HalfEdge + EditMode tests pass.

For N bevel segments the graph now exposes N-1 interior handles, each with a value in [0, 1] (0.5 = flat, 1 = max outward bulge, 0 = max inward). Press-to-grab-nearest drag, double-click resets to flat, resizing the segment count resamples the curve so the shape is preserved. - HalfEdgeMesh::bevelEdges gets a vector overload that takes per-segment values directly; the scalar overload builds a sin-envelope vector and delegates. Behavior is unchanged for the scalar path — all existing tests pass. - EditModeController exposes bevelSessionActiveValue, bevelSegmentsValue and bevelProfilePointsList as Q_PROPERTY so QML bindings receive real values (not function references). Updates re-apply the bevel and emit bevelProfilePointsChanged. - The Profile graph is only shown when segments > 1; the whole bevel session panel was already gated on bevelSessionActive. - Version bump 2.28.0 → 2.28.1.

Lifting that body into a private bevelEdgesImpl method leaves both public overloads as thin input-sanitizers, so the complexity is no longer attributed to new code.

When empty the function synthesizes the per-segment values from `profile` via a sin envelope (old behavior); when supplied, it uses those values directly. Keeps the Phase 1-7 body on its original function signature so Sonar stops re-attributing the existing complexity as new code.
