vectors

v4.2.1-alpha

Animation Mode for napkin-sketch, as a plugin: the /vectors:animation-mode command that draws one frame from the form the app writes, an animation-frame subagent that runs the same job in its own context, and the two skills behind them - vector-animations (assemblies, joint pivots, cycle tables, transform recipe, frame-spacing physics) and vector-graphics (Bezier formulas, degree choice, SVG layer structure, and a dependency-free script that derives path data from control points).

Included Skills1

vector-graphicsskills/vector-graphics/SKILL.md

Draw vector graphics from Bezier curve equations rather than by dragging control points. Use when creating, editing, simplifying, or reviewing SVG paths, icons, logos, letterforms, shape primitives, or the geometry behind an animation; when deciding between linear, quadratic, and cubic segments; when a path has more control points than its shape needs; when converting measured or traced points into path data; or when a curve must join another smoothly. Covers the Bernstein basis, De Casteljau subdivision, the convex hull property, continuity grades, SVG path commands (L, Q, T, C, S), and a dependency-free script that derives path data from control points. Also covers SVG layer management: nested <g> layer trees, layer naming across editors (id, inkscape:label, data-name, uniquifier suffixes), compound paths and their holes, fill-only shapes, and keeping structure and anchors intact through import/export round trips.
