trianglePlaneIntersection
fun trianglePlaneIntersection(p0: Cartesian3, p1: Cartesian3, p2: Cartesian3, plane: Plane): Any(source)
Computes the intersection of a triangle and a plane
const origin = Cartesian3.fromDegrees(-75.59777, 40.03883);
const normal = ellipsoid.geodeticSurfaceNormal(origin);
const plane = Plane.fromPointNormal(origin, normal);
const p0 = new Cartesian3(...);
const p1 = new Cartesian3(...);
const p2 = new Cartesian3(...);
// convert the triangle composed of points (p0, p1, p2) to three triangles that don't cross the plane
const triangles = IntersectionTests.trianglePlaneIntersection(p0, p1, p2, plane);Content copied to clipboard
Return
An object with properties positions and indices, which are arrays that represent three triangles that do not cross the plane. (Undefined if no intersection exists)
Parameters
p0
First point of the triangle
p1
Second point of the triangle
p2
Third point of the triangle
plane
Intersection plane
