Release Notes

Unreleased

• fbm2: fractal noise with configurable octaves, persistence and lacunarity.
• SimplePath.length, pointAt, tangentAt and pointsAlong: measure and sample paths by distance. alongPath passes each sampled point and angle to a callback.
• withSymmetry: repeat a drawing with rotational, mirror or kaleidoscope symmetry.
• curl2: a vector field derived from noise. SimplePath.flowLine traces paths through vector fields.
• SimplePath.boundingBox, area, containsPoint and convexHull: measure and query shapes. A standalone convexHull accepts arrays of points.
• SimplePath.simplified: reduce point count with a configurable tolerance.
• harmony: create colour schemes. mixColors: blend colours along the shortest route around the hue circle.
• worley2: cellular noise with configurable distance, metric and jitter. worleyCell2 returns feature-point details and an ID for colouring cells.
• SimplePath.offset: create parallel paths with mitred corners for ribbons and contours.
• forRadialTiling: divide rings into sectors, returning a HollowArc for each cell. Supports a centre hole and partial circles.

0.20.0

• Additional conversions from Arc, HollowArc, Ellipse, Circle and RoundedRect to SimplePath

0.19.0

• Fragment shader support (see shader examples).
  • Render a fragment shader to a texture (image) via renderShader
  • Render a Solandra sketch to a texture (image) via render
  • Pass images into shaders
  • Draw images in sketches with drawImage
  • Requires OffscreenCanvas; unavailable in Safari 16.x at release
• Poisson disc sampling iteration
• Pseudorandom angle generation
• transformLoopedPoints keeps the first and last points together during non-deterministic transformations
• rotateAround helper
• Removed a workaround for Safari text rendering at small font sizes
• Cached meta

0.18.0

• Added generative palettes based on Inigo Quilez's cosine palettes. Use palettePreset for named palettes or palette for custom coefficients. See an example.
