This paper presents an accurate and efficient method to solve both point projection and point inver NURBS curves and surfaces. We first subdivide the NURBS curve or surface into a set of Bézier subc patches. Based on the relationship between the test point and the control polygon of Bézier curve or the point net of the Bézier patch, we extract candidate Bézier subcurves or Bézier patches and then find the app candidate points. Finally, by comparing the distances between the test point and… CONTINUE READING
