fractionToPoint Method
Sum the triangle points with given scales.
- If the scales sum to 1, they are barycentric coordinates, and hence the result point is in the plane of the triangle. If all coordinates are non-negative then the result point is inside the triangle.
- If the scales do not sum to 1, the point is inside the triangle scaled (by the scale sum) from the origin.
fractionToPoint(b0: number, b1: number, b2: number, result?: Point3d): Point3d
@returns linear combination of the vertices of this triangle
