Type members

• static var shared: Geometry3D

  The shared instance of this class

• static func buildBoxPlanes(extents: Vector3) -> VariantCollection<Plane>

  Returns an array with 6 Planes that describe the sides of a box centered at the origin. The box size is defined by extents, which represents one (positive) corner of the box (i.e. half its actual size).

• static func buildCapsulePlanes(radius: Double, height: Double, sides: Int32, lats: Int32, axis: Vector3.Axis) -> VariantCollection<Plane>

  Returns an array of Planes closely bounding a faceted capsule centered at the origin with radius radius and height height. The parameter sides defines how many planes will be generated for the side part of the capsule, whereas lats gives the number of latitudinal steps at the bottom and top of the capsule. The parameter axis describes the axis along which the capsule is oriented (0 for X, 1 for Y, 2 for Z).

• static func buildCylinderPlanes(radius: Double, height: Double, sides: Int32, axis: Vector3.Axis) -> VariantCollection<Plane>

  Returns an array of Planes closely bounding a faceted cylinder centered at the origin with radius radius and height height. The parameter sides defines how many planes will be generated for the round part of the cylinder. The parameter axis describes the axis along which the cylinder is oriented (0 for X, 1 for Y, 2 for Z).

• static func clipPolygon(points: PackedVector3Array, plane: Plane) -> PackedVector3Array

  Clips the polygon defined by the points in points against the plane and returns the points of the clipped polygon.

• static func computeConvexMeshPoints(planes: VariantCollection<Plane>) -> PackedVector3Array

  Calculates and returns all the vertex points of a convex shape defined by an array of planes.

• static func getClosestPointToSegment(point: Vector3, s1: Vector3, s2: Vector3) -> Vector3

  Returns the 3D point on the 3D segment (s1, s2) that is closest to point. The returned point will always be inside the specified segment.

• static func getClosestPointToSegmentUncapped(point: Vector3, s1: Vector3, s2: Vector3) -> Vector3

  Returns the 3D point on the 3D line defined by (s1, s2) that is closest to point. The returned point can be inside the segment (s1, s2) or outside of it, i.e. somewhere on the line extending from the segment.

• static func getClosestPointsBetweenSegments(p1: Vector3, p2: Vector3, q1: Vector3, q2: Vector3) -> PackedVector3Array

  Given the two 3D segments (p1, p2) and (q1, q2), finds those two points on the two segments that are closest to each other. Returns a PackedVector3Array that contains this point on (p1, p2) as well the accompanying point on (q1, q2).

• static func getTriangleBarycentricCoords(point: Vector3, a: Vector3, b: Vector3, c: Vector3) -> Vector3

  Returns a Vector3 containing weights based on how close a 3D position (point) is to a triangle’s different vertices (a, b and c). This is useful for interpolating between the data of different vertices in a triangle. One example use case is using this to smoothly rotate over a mesh instead of relying solely on face normals.

• static func rayIntersectsTriangle(from: Vector3, dir: Vector3, a: Vector3, b: Vector3, c: Vector3) -> Variant

  Tests if the 3D ray starting at from with the direction of dir intersects the triangle specified by a, b and c. If yes, returns the point of intersection as Vector3. If no intersection takes place, returns null.

• static func segmentIntersectsConvex(from: Vector3, to: Vector3, planes: VariantCollection<Plane>) -> PackedVector3Array

  Given a convex hull defined though the Planes in the array planes, tests if the segment (from, to) intersects with that hull. If an intersection is found, returns a PackedVector3Array containing the point the intersection and the hull’s normal. Otherwise, returns an empty array.

• static func segmentIntersectsCylinder(from: Vector3, to: Vector3, height: Double, radius: Double) -> PackedVector3Array

  Checks if the segment (from, to) intersects the cylinder with height height that is centered at the origin and has radius radius. If no, returns an empty PackedVector3Array. If an intersection takes place, the returned array contains the point of intersection and the cylinder’s normal at the point of intersection.

• static func segmentIntersectsSphere(from: Vector3, to: Vector3, spherePosition: Vector3, sphereRadius: Double) -> PackedVector3Array

  Checks if the segment (from, to) intersects the sphere that is located at spherePosition and has radius sphereRadius. If no, returns an empty PackedVector3Array. If yes, returns a PackedVector3Array containing the point of intersection and the sphere’s normal at the point of intersection.
