The modeling package has been fundamentally changed to acheive several goals.

• math functions have been rewritten based on the glmatrix library, which is array based data
• geometry has been simplified to arrays of data to improve memory usage and performance
  • geom2 - 2D geometries
  • geom3 - 3D geometries
  • path2 - 2D paths
• APIs have been standardized, and now align to JavaScript standards for interoperability
• tests for everything, no more unknowns

const { arc } = require('@jscad/modeling').primitives

• arc, line
• circle, ellipse, rectangle, roundedRectangle, square, star
• cube / cuboid / roundedCuboid, sphere / ellipsoid, cylinder / cylinderElliptic / roundedCylinder, geodesicSphere, polyhedron, torus
• NEW line 2D primitive
• NEW star 2D primitive
• NEW ellipsoid 3D primitive
• CHANGED cylinder definition to use 'height'
• APIs have been standardized
• all angles / rotations are now based on radians. Use degToRad() to convert easily.
• major rewrites of cylinder, roundedRectangle, roundedCube
• bug fixes

MAJOR CHANGE primitives are centered at 0,0,0 only. use translate() to position the shape

const { center } = require('@jscad/modeling').transforms

• align, center, mirror, rotate, scale, transform, translate
• NEW align
• APIs have been standardized
• all rotations are now based on radians. Use degToRad() to convert easily.
• bug fixes

MAJOR CHANGE: transforms are accumlated so the order of transforms is now important

const { intersect } = require('@jscad/modeling').booleans

• intersect, subtract, union
• APIs have been standardized
• bug fixes

const { measureArea } = require('@jscad/modeling').measurements

• measureArea, measureBounds, measureEpsilon, measureVolume
• RENAMED bounds to measureBounds
• RENAMED area to measureArea
• RENAMED volume to measureVolume
• NEW measureEpsilon
• NEW aggregate versions of measurements
• major rewrites of measureArea and measureVolume

const { expand } = require('@jscad/modeling').expansions

• expand, offset
• APIs have been standardized
• NEW expand function for 2D paths
• NEW offset function for 2D paths and 2D geometries
• bug fixes

NOTE: Contraction is a negative (-) expansion.

const { extrudeLinear } = require('@jscad/modeling').extrusions

• extrudeLinear, extrudeRectangular, extrudeRotate, extrudeFromSlices
• APIs have been standardized
• RENAMED linear_extrude to extrudeLinear
• RENAMED rectangular_extrude to extrudeRectangular
• RENAMED rotate_extrude to extrudeRotate
• RENAMED solidFromSlices to extrudeFromSlices
• all angles / rotations are now based on radians
• major rewrites of all extrusions

const { hull } = require('@jscad/modeling').hulls

• hull, hullChain
• APIs have been standardized
• RENAMED chain_hull to hullChain
• NEW hull and hullChain for 2D paths
• NEW hull and hullChain for 3D geometries

const { vectorChar } = require('@jscad/modeling').text

• vectorChar, vectorText

const { colorize } = require('@jscad/modeling').colors

• colorize
• colorNameToRgb, hexToRgb, hslToRgb, hsvToRgb, hueToColorComponent
• rgbToHex, rgbToHsl, rgbtoHsv
• NEW colorize for 2D geometries and 2D paths
• REMOVED color using names, use colorNameToRgb

MAJOR CHANGE: Colors are applied at the geometry level. Colors must be applied as the last step, as other operations create new geometry.

• REMOVED CSG, CAG, etc. objects
  • See Object API
• REMOVED OpenSCAD functions / function signitures
• REMOVED OpenSCAD math functions
  • See JavaScript Math
• REMOVED old text functions
  • vector_char (Use NEW vectorChar)
  • vector_text (Use NEW vectorText)
• REMOVED functionality for 3D geometries
  • lieFlat
  • getTransformationToFlatLying
  • getTransformationAndInverseTransformationToFlatLying
  • stretchAtPlane
  • cutByPlane
  • sectionCut
• REMOVED functionalty for 2D geometries
  • overCutInsideCorners
  • extrudeInOrthonormalBasis
  • extrudeInPlane

NOTE: We expect REMOVED functionality to be supported via small user libraries.
