Effects parity

Last reviewed: 2026-10-10 · Last updated: 2026-10-13 · Change: minor (3D and Materials: Inflate takes Twist, Taper and Cap; score unchanged) · Target: Adobe Illustrator 2026 (30.x)

Every entry of Illustrator's Effect menu, by its public feature name, against VectorCraft's effects catalogue (effect_catalog() in crates/effects/src/lib.rs) and the Effect menu built from it (crates/ui-egui/src/menus.rs). Counts are measured from the catalogue; "depth" notes are estimated. Part of target-app-parity.md; open work is in gaps.md.

The pixel-filter pipeline (vectorcraft_effects::pixel) is in place: each new filter is one function, a catalogue row, a menu entry and translations. Measured throughput: 0.7–1.2 agent hours per filter (see calibration), so the 28 missing filters are ~19–34 h and the Effect Gallery dialog another 4–6 h. These parallelize well across agents.

Film Grain (artistic.filmGrain, Effect › Artistic) adds stable monochrome noise to shadows and midtones, with Grain, Highlight Area and Intensity sliders, live preview and appearance editing. Its smooth grain field follows translations, preserves transparency and stays in document units; zoomed-out rendering uses bounded approximate footprint filtering. Changing the bounds shifts the pattern. Command exports bake it to an image in SVG and PDF, while the native document keeps the effect editable. Behaviour is an original visual approximation based on Illustrator's public effects reference and the public Artistic filters guide, not a pixel-identical proprietary implementation. Intensity is interpreted as highlight strength and quieter highlight grain. Grain strength stays even across shadows and midtones and rolls off above mid-grey to a quarter-strength floor at full Intensity before highlight headroom; cream retains soft grain, black takes light speckles and white stays clean. The tonal curve and endpoint behaviour are interpretations, not verified proprietary behaviour. Saturated colour channels may clip. The parameter ranges and defaults are chosen for VectorCraft, not asserted as measured proprietary defaults. Near white, highlight headroom can limit grain equally at every Intensity; highlight lift still depends on Intensity when Highlight Area is nonzero. The two rotated, variance-normalised noise layers can leave a faint diagonal weave at high magnification. Removing that remaining direction would require a more expensive field; the current implementation keeps bounded per-pixel work. Film Grain is still slower than Texture Grain (Regular), particularly when its wider footprint needs four samples. Calibration on uniform grey at Grain 20, using 32×32 fine samples per coarse pixel, measured grain standard deviation within about 15% of the dense area average at pixel widths of 2, 4 and 8 document units (ratios 1.13, 0.89, 0.85). This is evidence for the bounded approximation, not an accuracy guarantee for arbitrary artwork. Tests: pixel::tests::film_grain_*, tests_rasterfilters, tests_adjust::film_grain_dialog_* and tests_labels::effect_menu_lists_film_grain_*.

3D and Materials

Item	Ours
Revolve	initial: live, editable profile, rotation and light gizmos, flat shading, SVG/PDF output, Expand Appearance (revolve.md, #846)
Extrude & Bevel, Inflate, Rotate	initial: live, depth, twist, taper, solid or hollow caps, five original bevel shapes, Inflate volume, both sides, twist, taper and cap, Rotate of every fill and stroke, Position presets, rotation and light gizmos, SVG/PDF output, Expand Appearance (three-d.md)
Materials panel, lighting, ray-traced render	one directional light with flat shading only; no materials, several lights, light colour, shadows or ray tracing
3D (Classic): Extrude & Bevel, Revolve, Rotate	none
Turntable (30.0 beta)	none
Export 3D objects (OBJ, USDA, glTF)	none

The three-d crate (depends only on geom) builds, rotates, projects, shades and depth-sorts the surfaces; the effects crate turns them into art. What's left (materials, several lights and shadows, ray-traced rendering, Revolve caps, 3D Classic, Turntable, 3D export) is 25–45 h.
