vectory

A 2D geometry library in Scala.

Dependency

For Scala and ScalaJS:

libraryDependencies += "com.github.fdietze" % "vectory" % "master-SNAPSHOT"

When using JitPack, it is often more useful to point to a specific commit, to make your builds reproducible:

libraryDependencies += "com.github.fdietze" % "vectory" % "d0e70f4"

Example

import vectory._

Vec2(1,2) + Vec2(3,4) // Vec2(4.0,6.0)
Vec2(1,2).length // 2.23606797749979
Vec2(1,2).normalized // Vec2(0.4472135954999579,0.8944271909999159)
Vec2(1,2).angle // 1.1071487177940904
Vec2(1,2) dot Vec2(3,4) // 11.0
Vec2(1,2) cross Vec2(3,4) // -2.0
Vec2(1,2) * 5 // Vec2(5.0,10.0)

val a = Line(Vec2(1, 3), Vec2(4, 1))
val b = Line(Vec2(2, 1), Vec2(3, 3))
a intersect b // Some(LineIntersection(Vec2(2.5,2.0),true,true)) -- point lies on both segments

val c = Circle(Vec2(3, 1), 2)
val r = AARect(Vec2(1, 1), Vec2(6, 4))
c intersects r // true

val p = ConvexPolygon(IndexedSeq(Vec2(-3, 1), Vec2(-1, -2), Vec2(2, 2)))
val c = Circle(Vec2(-1, -4), 3)
p intersectsMtd c // Some(Vec2(-0.0,-1.0))

val p = ConvexPolygon(Array(Vec2(-2, -2), Vec2(-3, -1), Vec2(2, -2), Vec2(1, 3)))
p.aabb // AARect(Vec2(-0.5,0.5),Vec2(5.0,5.0))

Primitives

• Vec2(x: Double, y: Double)
• LineLine(start: Vec2, end: Vec2)
• Circle(center: Vec2, r: Double)
• AARect(center: Vec2, size: Vec2) - Axis aligned rectangle
• RotatedRect(center: Vec2, size: Vec2, angle: Double) - Rotated rectangle
• ConvexPolygon(verticesCCW: IndexedSeq[Vec2]) - Convex polygon with vertices in counter-clockwise order

Algorithms

• Point-Line distance
• Point-Line-Segment distance
• Project point on line
• Axis-aligned bounding-box for a set of vertices
• Line-Line intersection returning intersection points
• Line-ConvexPolygon intersection returning intersection points
• Circle-AARect intersection returning intersection points
• Circle-ConvexPolygon intersection test
• Circle-ConvexPolygon intersection returning MTD (Minimum Translation Distance) vector
• ConvexPolygon-ConvexPolygon intersection returning MTD (Minimum Translation Distance) vector
• Clamp Line by ConvexPolygon
• Convex Hull of Points
