Unreleased

0.6.3.1

• Fix potential segfault in shapePaths

0.6.3.0

• Fixed an issue in Waterfall.Transforms where negative coefficients to scale would produce a broken Solid
• Added optics derived from the Transformable typeclass, _translated, _scaled, _uScaled, _rotated, _mirrored and their 2D equivalents.
• Operations that can fail (roundFillet, chamfer, offset, loft, sweep, revolution and their relatives) now fall back to an empty Solid rather than throwing. Added try* variants (tryRoundFillet, tryOffset, tryLoft, trySweep, tryRevolution, etc) that return Either WaterfallError, along with a new Waterfall.Error module.

0.6.2.1

• Fixed an off by one error in Waterfall.TwoD.repeatLooping that would produce overlapping wire segments in repeatLooping

0.6.2.0

• Added Waterfall.Path.Common.pathLength, Waterfall.Path.pathLength3D and Waterfall.TwoD.Path2D.pathLength2D
• Added Waterfall.Path.Common.takePathFraction, Waterfall.Path.takePathFraction3D and Waterfall.TwoD.Path2D.takePathFraction2D

0.6.1.0

Added

• Added Waterfall.Solids.torus
• Added Platonic Solids:
  • Waterfall.Solids.tetrahedron
  • Waterfall.Solids.octahedron
  • Waterfall.Solids.icosahedron
  • Waterfall.Solids.dodecahedron

0.6.0.1

Added

• Added whenNearlyEqual to Waterfall.Fillet to make writing conditional Fillets easier

Fixed

• Workaround for an issue where calling scale with a uniform scale vector produced invalid geometry

0.6.0.0

Added

• Added Boolean typeclass providing boolean operations on both 2D and 3D objects
  • union, intersection, difference, unions, intersections and operators (~/\~), (~\/~), (~-~) are now polymorphic
• Added 2D boolean operations: union2D, difference2D, intersection2D, unions2D, intersections2D
• Added emptyShape for 2D shapes
• Added Waterfall.TwoD.Booleans module
• Added chamfer, conditionalChamfer and indexedConditionalChamfer to Waterfall.Fillet

Changed

• Renamed union to union3D, difference to difference3D, intersection to intersection3D for 3D operations
• Renamed unions to unions3D, intersections to intersections3D for 3D batch operations
• Renamed nowhere3D to emptySolid

0.5.1.1

Added

• Added unitPolygon

0.5.1.0

Added

• Added unions, intersections, and specialized mconcat for Solid to improve performance

0.5.0.1

Fixed

• direction of internal edgeValue function, used by waterfall-cad-svg package

0.5.0.0

Added

• Add splice/splice2D/splice3D functions
• Add splitPath/splitPath3D/splitPath2D functions
• Add Epsilon constraint to closeLoop fixing behaviour when endpoints are very close together
• Add matTransform and matTransform2D methods to the Transformable and Transformable2D typeclasses, respectively
• Add shapePaths to Waterfall.TwoD.Shape

Changed

• Most functions in Waterfall.Path.Common now have an Epsilon constraint
• pathEndpoints/pathEndpoints3D/pathEndpoints2D now returns a Maybe (in case of an empty path)
• offset now no longer takes a tolerance
  • offsetWithTolerance is available if this is required
• pointedLoft and loft now no longer takes a precision argument
  • pointedLoftWithPrecision is available if this is required
• Rename fromPath to makeShape as I think this will result in more readable code

Fixed

• fixed behaviour when scaling with a unit vector (no scaling)
• fixed Path/Path2D representation, so that the Monoid instance mempty value no longer generates crashes

0.4.0.0

• Add Waterfall.Loft containing loft and pointedLoft
• Change the Monoid instance for Path and Path2D, so that in the expression a <> b a line is added between the end of a and the start of b, unless these points are coincident.
• Reverse the order in which Path.pathFrom adds path segments; required by the new Monoid behaviour.
• Add Waterfall.Path.Common.reversePath, reversing the direction of a Path or Path2D, along with monomorphised versions reversePath3D and reversePath2D
• Fix order of rotation of Waterfall.TwoD.Path2D.repeatLooping

0.3.0.1

Added

• Add pathEndpoints, pathEndpoints2D and pathEndpoints3D

0.3.0.0

Changed

• The project now depends on (and supports) OpenCascade 7.8.0 or later

0.2.2.1

Fixed

• Importing files that contain multiple separate solids should no longer error

0.2.2.0

Added

• New functions in Waterfall.IO
  • Support for reading (as well as writing) all file formats
    • readSTL, readSTEP, readGLTF, readGLB, readOBJ
  • (Wavefront) OBJ support (writeOBJ)
  • Convenience methods readSolid and writeSolid inferring the format from the file extension

Changed

• Make error handling for actions in Waterfall.Text throw a WaterfallIOException on failure

0.2.1.0

Added

• GLTF (graphics library transmission format) support: writeGLTF and writeGLB in Waterfall.IO
• obj file format support writeOBJ in Waterfall.IO

0.2.0.0

Added

• the following volume, momentOfInertia and centerOfMass queries in Waterfall.Solids
  • volume
  • momentOfInertia
  • centerOfMass
• aabbToSolid to Waterfall.Solids (converts the output of axisAlignedBoundingBox into a solid)
• Waterfall.BoundingBox.AxisAligned, for calculating (and reifying) an (axis aligned) bounding box of a solid
• Waterfall.BoundingBox.Oriented, for calculating (and reifying) an (oriented) bounding box of a solid

Changed

• Changed the representation of Solid (and other Waterfall values) from a newtype wrapper to Data.Acquire to a naked Ptr, with destructors called using Finalizers.
  • This means it's possible to support "queries", like calculating the volume of a Solid
  • It also means there's some risk of exceptions being thrown when working with plain values, which wasn't present before
• Waterfall.Text.fontFromPath and Waterfall.Text.fontFromSystem now return IO actions rather than embedding the action into the underlying Shape

Fixed

• Typo in documentation for Waterfall.Solids.unitCone

0.1.2.2 - 2024-01-09

Fixed

• Fixed dependency versions

0.1.2.1 - 2024-01-09

Added

• Added mirror to Transformable typeclass, and mirror2D to Transformable2D
• Added fromPath2D to Waterfall.Path to make 2D paths into 3D ones.
• Added centeredCylinder and unitCone to Waterfall.Solids

Fixed

• Handle offsetting by zero (return the unmodified shape)
• Fix rotation of endcaps in a sweep

0.1.1.1 - 2023-12-12

0.1.1.0 - 2023-12-12

Added

• Add Waterfall.Offset, offsetting an object by a certain amount
• Add unitCircle, unitSquare and centeredSquare to Waterfall.TwoD.Shape

Fixed

• Correctly rotate and translate endcaps to the Path in a sweep

0.1.0.0 - 2023-12-05

Added

• Reexported all modules under top level Waterfall module
• Refactored common code in Path and Path2D into the AnyPath typeclass
• Added Waterfall.Text, containing text rendering functions

Fixed

• Fix build on MacOS (tested with the homebrew install of OpenCASCADE)
