API Reference > geometry-core > CartesianGeometry > Vector3d > createCrossProductToPoints createCrossProductToPoints MethodStatic Return the cross product of the vectors from origin to pointA and pointB. the result is a vector the result is perpendicular to both vectors, with right hand orientation the magnitude of the vector is twice the area of the triangle. createCrossProductToPoints(origin: Readonly<WritableXYAndZ>, pointA: Readonly<WritableXYAndZ>, pointB: Readonly<WritableXYAndZ>, result?: Vector3d): Vector3d Parameter Type Description origin Readonly<WritableXYAndZ> pointA Readonly<WritableXYAndZ> pointB Readonly<WritableXYAndZ> result Vector3d Returns - Vector3d Defined in geometry3d/Point3dVector3d.ts Line 650 Last Updated: 12 June, 2024
