Class: PhysicalPlateConnectivityTester

Determines how two plates are connected (physically) with each other The algorithm for non-coplanar plates is based on the fact that non-coplanar plates can only intersect in one line. This means, that instead of fully intersecting the plates with each other like it was done so far, which would be O(n * m), where n and m are the number of section in their outlines, we only intersect the intersection line with the plates in 2D, which is O(n + m), and thus we get a huge performance gain for plates with many lines. The first thing we do is getting the intersection line in 3D (infinite line). Then we intersect this line with the plates in 2D, as the intersection line is in the plane of both plates. Then we take these intersections to determine where the intersection line is inside, outside or on a section of the plates. Then we use this information to get the joints that can be created.

Defined in src/model/data/PhysicalObject/PhysicalPlateConnectivityTester.ts:337

Parameters:

Name Type
insideOutsideA LinePosition
insideOutsideB LinePosition
coefficient1 number
coefficient2 number
line Line3

Returns: IJointPosition

Static Private _pointDistanceToLine2D

▸ _pointDistanceToLine2D(line: Line3, point: Vector3): number

Defined in src/model/data/PhysicalObject/PhysicalPlateConnectivityTester.ts:397

Parameters:

Name Type
line Line3
point Vector3

Returns: number

Static Private _sideOfLine2D

▸ _sideOfLine2D(line: Line3, point: Vector3): boolean

Static getInsideOutsideFromIntersections

▸ getInsideOutsideFromIntersections(intersections: Intersection[], outerBounds: IBounds): LinePosition[]

Defined in src/model/data/PhysicalObject/PhysicalPlateConnectivityTester.ts:175

An "InsideOutside" describes a part of the intersection line in relation to the plate. "inside" means that the line is inside the plate, "outside" means that the line is outside the plate, "section" means that the line is on a section. The "InsideOutsides" only store their starting coefficient, the ending coefficient is determined by the next "InsideOutside".

Parameters:

Name Type
intersections Intersection[]
outerBounds IBounds

Returns: LinePosition[]
