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.

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 24 missing filters are ~17–29 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.
Cutout, Neon Glow and Poster Edges (artistic.cutout, artistic.neonGlow, artistic.posterEdges)
follow the same two public references, with original algorithms. Cutout softens the object's colours (Edge Simplicity, less with Edge
Fidelity), splits each colour channel into Number of Levels steps, and paints each resulting piece
in the average colour that falls into it, so hues survive. Poster Edges
posterizes each colour channel to Posterization + 2 levels and draws black lines on the edges of
any channel and of the object's outline, wider with Edge Thickness and darker, on fainter edges
too, with Edge Intensity. Neon Glow redraws the object in dimmed greys screened with a glow colour
from its light areas (positive Glow Size) or its dark ones (negative), spread by the size and as
strong as Glow Brightness; with no foreground and background colours in Illustrator's model, the
glow colour is the effect's own parameter. All three keep coverage, work in document units at any
Document Raster Effects resolution, and use the generic effect dialog with live preview. Ranges and
defaults are chosen for VectorCraft. Evidence: crates/effects/src/pixel/artistic.rs, the
artistic_*, cutout_*, poster_edges_* and neon_glow_* tests in crates/effects/src/pixel/tests.rs,
and artistic_settings_survive_a_save_and_open in crates/engine/src/tests_rasterfilters.rs.
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_*.

The three-d crate (depends on geom and pathops, with no UI or GPU dependencies) 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,
angular cut caps, exact visibility, 3D Classic, Turntable, 3D export) is 25–45 h.
Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-16 | minor | Zig Zag with Smooth points draws a continuous wave: every peak and valley is a smooth point with handles along the path, a third of the way to the next ridge, so each span follows a half cosine through the path instead of a straight diagonal with rounded tips, also at the ends of open paths and for ridges much taller than they are apart (#2343); score unchanged (estimated) |
| 2026-10-16 | minor | G2: Effect › Sketch › Halftone Pattern (Size, Contrast, Pattern Type Circle, Dot or Line; black ink on white paper, Size in points at any Document Raster Effects resolution); measured Photoshop filters 30/57, 27 remaining (22–38 h). |
| 2026-10-15 | minor | Round Corners rounds corners whose anchor carries a handle (where a curve meets a line, or two curves meet) with the round cut Live Corners uses (#1144), reaching radius along each side; before, they were left sharp. Corners between handle-less anchors are rounded as before; score unchanged (estimated) |
| 2026-10-14 | minor | Revolve: automatic smooth vector shading, default-on Cap with continuous curved rims, and bounded seam joins; angular cut sides remain open. Scores and hour estimates unchanged at this rounding |
| 2026-10-14 | minor | Wide drop shadows and glows at high zoom render within the raster budget (#1706); stacked Transform effects are bounded (#1705); 3D effects keep the area a nonzero compound path fills (#1724); pattern tiles redraw when a symbol, pattern or image their art shows changes (#1723) (all #1864). Scores unchanged (estimated) |
| 2026-10-14 | minor | Roughen with Smooth keeps turn-backs smooth instead of making cusps that draw as spikes (#1646, #1643); Scribble draws one zig-zag per region, with no lines across holes and notches; convex shapes are unchanged (#1651, #1648); scores unchanged (estimated) |
| 2026-10-13 | minor | Zig Zag spaces its ridges evenly along each segment, so lines and curves get a regular wave in Corner and Smooth (#1558); Warp › Arc (the effect and Envelope › Make with Warp) bends in the object's real proportions: a circular arc with concentric edges and no fold-over at 100%, so Arc on art that isn't square draws differently from before (#1581, fixes #1578); effect.apply and effect.setParams give an error for a misspelt or wrongly typed effect parameter instead of running the effect with its default (#1623, #1592); scores unchanged (estimated) |
| 2026-10-13 | minor | 3D lighting takes the documented Intensity, Rotation, Height, Softness and Ambient Light (to 200 %), and a light behind the object; earlier lights read as the same (three-d.md); 3D stays ~25%, 25–45 h |
| 2026-10-13 | minor | 3D Perspective is the documented 0°–160° angle, earlier strengths read as the same view (three-d.md); 3D stays ~25%, 25–45 h |
| 2026-10-13 | minor | Raster effects (blur, shadow, glow, grain) drawn after a pattern, radial or freeform gradient fill export at their place and size (#1541, fixes #1536); scores unchanged (estimated) |
| 2026-10-13 | minor | 3D and Materials: outlined words and other shapes of many small curves take Rotate, Extrude & Bevel and Inflate (curves are sampled by a tolerance; Rotate takes up to 65,536 outline points; #1481); Extrude & Bevel's Twist runs 0° to 360° as the public panel reference gives it, a negative value drawing untwisted (#1524); a twisted extrusion keeps its walls, which were dropped from about 45° (#1525); details in three-d.md; 3D stays ~25%, 25–45 h (estimated) |
| 2026-10-13 | minor | Inflate takes Twist, Taper and Cap (three-d.md); 3D stays ~25%, 25–45 h: materials, lights and shadows are the bulk of what remains |
| 2026-10-12 | minor | Extrude & Bevel, Inflate and Rotate (initial, three-d.md); 3D ~8% → ~25%, 45–75 → 25–45 h |
| 2026-10-12 | minor | G2: Artistic › Film Grain added with live controls and raster exports; measured Photoshop filters 29/57, 28 remaining (23–39 h). |
| 2026-10-11 | minor | PDF cap warnings identify original objects after appearance splitting and report the lowest achieved ppi; cap/rendering and scores unchanged |
| 2026-10-11 | minor | Zig Zag's dialog: Size and Ridges per segment sliders, Points as Smooth / Corner radio buttons (#1133) |
