Fix Wall Height module not changing when editing multiple walls. ## 0.3.16 Fix undefined quadtree in `CanvasEdges`. Catch when a polygon, ellipse is not positive and don't use WeilerAtherton. ## 0.3.15 Add quadtree to `CanvasEdges`. Split out `Edge` vs `CanvasEdge` patches. Fix handling of negative values in `convertToDistanceCutaway`. ## 0.3.14 Move `CutawayPolygon` and related cutaway methods to libGeometry. ## 0.3.13 More fixes for the `alternatingGridDistance` test. ## 0.3.12 Fix alternating test in `alternatingGridDistance` so it does 5/10/5, not 10/5/10. ## 0.3.11 Add `HexGridCoordinates3d` class. Add `roundNearWhole` utility. ## 0.3.10 Set diagonals to the game setting for hex grids. ## 0.3.9 Move `Point3d._tmp` to a static object and add `_tmp` for subclasses. Add `RegionWaypoint3d`, `GridCoordinates`, and `GridCoordinates3d` classes. ## 0.3.8 Fix `findOverlappingPoints` when one segment is completely encompassed by a longer segment. (Was returning 1 endpoint when should be returning 2 endpoints.) ## 0.3.7 Add `cutaway` methods to construct a vertical 2d slice of a 3d shape. Add `rotateAroundCenter` method to `PIXI.Rectangle`. ## 0.3.6 Fix for tile pixel cache in v12. Add `localNeighbors` and `localPixelStep` methods to PixelCache. ## 0.3.5 Use PIXI.Points for `_fixedPoints` in CenteredPolygon so that the points can be rotated. Closes issue #108 in Elevation Ruler. Add `ClipperPaths#joinPaths` method. Passthrough pregenerated edges for `Polygon#lineSegmentIntersects` to avoid rebuilding the edges if not necessary. ## 0.3.4 Handle Wall, Edge classes in Draw.segment. Add an internal PIXI.Point.invert that returns object, for non-keys. Fix for test if can convert polygon to rectangle. Add `ClipperPaths#union` method that unions polygons without filling. ## 0.3.3 Switch to using TextureLoader.getTextureAlphaData. Fix the `fromOverheadTileAlpha` method given changes to `TextureLoader.getTextureAlphaData`. Use `wall.edge.a`. Change Tile overhead test. ## 0.3.2 Use `token#getShape()` instead of `token#shape` in `token#tokenBorder` so it works even if the token shape is not yet defined. Use `wall.edge.a` instead of `wall.A`. ## 0.3.1 Add temporary static points to `PIXI.Point` and `Point3d`. Redo constrained token border to use CanvasEdges in v12. Change `Math.clamped` to `Math.clamp`. Deprecate `Token#tokenShape`. ## 0.3.0 Foundry v12 compatibility. No tested backwards compatibility. Removed `Math.SQRT3` which is now set in base Foundry. Add `roundDecimals` to `CONFIG.GeometryLib.utils`. Change `getProperty` to `foundry.utils.getProperty`. Change `canvas.grid.isHex` to `isHexagonal`. ## 0.2.20 Fix for `Circle.prototype.area` calculation. ## 0.2.19 Add `Ellipse.prototype.lineSegmentIntersects`. ## 0.2.18 Add enumerated `IX_TYPES` and segment functions: - `doSegmentsOverlap` - `findOverlappingPoints` - `segmentCollision` - `endpointIntersection` - `segmentIntersection` - `segmentOverlap` ## 0.2.17 Add `PixelCache` to geometry API. Track tile updates and update the tile pixel cache accordingly if the cache is present. Change registration flow to not rely on old versions of Patcher. Add grid units to all elevation configurations. Fix setting values for elevation configurations and display of values in the config. Fix libWrapper error when setting multiple elevation placeable configs. Fix for point sources not having `elevationE` and `elevationZ` getters. Fixes issue with elevated vision shadows being too long. ## 0.2.16 Avoid WeilerAtherton in constrained token border for now as it returns failed polygons when a wall intersects at a border point. Refactor `PIXI.Polygon.prototype.viewablePoints` to avoid intersection testing by taking the points with the largest angles as CW and CCW. This is faster and hopefully more accurate. Test for points contained within the polygon and for degenerate polygons. ## 0.2.15 Add checks to ensure that when measuring distance between points, missing x, y, or z properties will be treated as 0. Switch to faster `||` when testing for missing z properties. Also catches NaN values. ## 0.2.14 Return `PIXI.Point` for edge vertices when iterating edges for `PIXI.Rectangle`. Add `iteratePoints` method to `PIXI.Rectangle`. Add `constrainedTokenBorder` methods to `Token` along with associated hooks for tracking wall updates. Remove unconnected vertices after removing edges from a `Graph`. ## 0.2.13 Turn off console warnings for locating visible points. ## 0.2.12 Update Hexagon to better handle height/width. Edits to make elevation config appear properly in tiles and templates configs. Add `lineSegmentIntersects` method to `PIXI.Circle`. ## 0.2.11 Use source.document instead of source.data. Set point sources to max integer elevation if undefined, to mimic infinite height. Use updated Patcher class. Add elevation config registration. ## 0.2.10 Add ShapeHoled classes. Add envelop methods. Add Draw.removeLabel method. Add rectangle union method. ## 0.2.9 Catch when `actor.statuses` is undefined. ## 0.2.8 Avoid setting tile elevation to null. Don't overwrite tile elevation if it is undefined. Avoid changing tile elevation if EV is not active. ## 0.2.7 Fix `Square.prototype.getBounds` when returning a square rotated 45º. Use Set test instead of switch for checking if the square is rotated 0º or 45º. Add `Square.prototype.toRectangle`. ## 0.2.6 Allow registration of newer version of geometry lib, skipping if newer version already registered. Deregister hooks as needed. (Note: Hook deregistration will only work from this version on.) Add isProne getter to Token. ## 0.2.5 Fixes for testing overlaps. Improved test for circle-polygon overlap; fix for rectangle-polygon overlap. Copy centered polygon when translating. ## 0.2.4 - Fix calculation of polygon centroid. - Correct error when rotating fixed points. - Sync TileDocument.prototype.elevation - Catch when VisionSource has no x,y; use object (token) center instead - Add check for whether the DUCKING Levels property is present ## 0.2.3 - Fixes to infinite shadow polygons - Add `invertKey` and `fromAngle` methods. ## 0.2.2 - Don't use cached elevation properties, to avoid caching problems and simplify approach. - Use token topE for VisionSources. ## 0.2.1 - Fix for PIXI.Point.key getter. - Use the new v11 status set to check for prone. - Updates to how the elevation getters work and sync. ## 0.2.0 v11 fixes.
