PGS now uses Java 17+.

Added

  • findShortestTour() to PGS_PointSet. Computes an approximate Traveling Salesman path for a set of points.
  • pruneSparsePoints() to PGS_PointSet. Prunes a list of points by removing points that are considered not sufficiently dense (far away from their nearest neighbours); a counterpart to prunePointsWithinDistance().
  • Additional method signature for PGS_Morphology.variableBuffer() that accepts a callback function to define the buffer value at each vertex.
  • boundsCenter() to PGS_Transformation. Computes the center of the bounding box of a shape.
  • Additional method signature for delaunayTriangulation(points) that supports a boundary constraint.
  • fix() to PGS_Processing. Attempts to fix shapes with invalid geometry.
  • Additional method signature for frontChainPack() that accepts a random seed.
  • isClockwise() to PGS_ShapePredicates. Determines if the vertices of the specified shape form a clockwise loop.
  • extractInnerVertices() to PGS_Meshing. Extracts all inner vertices from a mesh.
  • thomasClusters() to PGS_PointSet. Generates random points having clustered properties using the Thomas Point Process.
  • transform() and transformWithIndex()* to PGS_Processing. Applies a specified transformation function to each child of the given PShape and returns a new PShape containing the transformed children (*additionally with child's index).
  • apply() and applyWithIndex()* to PGS_Processing. Applies a specified function to each child of the given PShape (*additionally with child's index).
  • toContours() to PGS_Conversion. Extracts the contours from a POLYGON or PATH PShape, represented as lists of PVector points.
  • segmentsOnExterior() to PGS_Processing. Extracts evenly spaced dashed line segments along the perimeter of a shape.
  • multiplicativelyWeightedVoronoi() to PGS_Voronoi . Generates a Multiplicatively Weighted Voronoi Diagrams diagram for a set of weighted sites.
  • applyRandomWeights() to PGS_PointSet. Applies random weights within a specified range to a list of points.
  • findContainingFace() to PGS_Meshing. Finds the single face from the mesh that contains the query point.
  • findBreaks() to PGS_Meshing. Returns the locations of invalid mesh face boundary segments if found.
  • pinchWarp() to PGS_Morphology. Applies a pinch warping effect to a shape, distorting vertices towards a specified point.

Changes

  • Packed circles from PGS_CirclePacking.stochasticPack() will now always lie within shape bounds.
  • PGS_Processing.pointsOnExterior() methods now respect GROUP shapes and holes (inner rings) and will populate them with points.
  • PGS_Morphology.simplifyDCE() now supports GROUP shapes and polygon holes.
  • PGS_Morphology.interpolate() is much faster on shapes with many vertices.
  • Removed superfluous height argument from PGS.createSupercircle() method signature.
  • Renamed fromPVector(shell, holes) in PGS_Conversion to fromContours(shell, holes).
  • Moved PGS_Processing.cleanCoverage() to PGS_Meshing and renamed to fixBreaks().

Fixed

  • urquhartFaces(), relativeNeighborFaces(), gabrielFaces() and spannerFaces() from PGS_Meshing now preserve holes from the input.
  • The output of PGS_Morphology.smoothGaussian() is no longer (slightly) affected by the vertex ordering of the input.
  • The transform and reference arguments for PGS_Transformation.align() were the wrong way round.

Removed

  • simplifyDCE(shape, targetNumVertices) and simplifyDCE(shape, vertexRemovalFraction) in favour a single method that accepts a user-defined termination callback that is supplied with the current vertex candidate's coordinate, relevance score, and the number of vertices remaining.
