getInterpolation( point, v1, v2, v3, target ) {

		return Triangle.getInterpolation( point, this.a, this.b, this.c, v1, v2, v3, target );

	}
Computes the value barycentrically interpolated for the given point on the
triangle. Returns `null` if the triangle is degenerate.

@param {Vector3} point - Position of interpolated point.
@param {Vector3} v1 - Value to interpolate of first vertex.
@param {Vector3} v2 - Value to interpolate of second vertex.
@param {Vector3} v3 - Value to interpolate of third vertex.
@param {Vector3} target - The target vector that is used to store the method's result.
@return {?Vector3} The interpolated value.
