API Reference > geometry-core > CartesianGeometry > Plane3dByOriginAndVectors > fractionToPoint fractionToPoint Method Evaluate a point a grid coordinates on the plane. The computed point is origin + vectorU * u + vectorV * v fractionToPoint(u: number, v: number, result?: Point3d): Point3d Parameter Type Description u number coordinate along vectorU v number coordinate along vectorV result Point3d optional result destination. Returns - Point3d Return the computed coordinate. Defined in core/geometry/src/geometry3d/Plane3dByOriginAndVectors.ts Line 163 Last Updated: 13 June, 2024
