I have an irregularly shaped patch between 4 points in space. How do extract information of all the points on the surface of the patch? I am asking this so as to perform intersection operations between two irregular shaped patches.

  • You mean [polygons](http://en.wikipedia.org/wiki/Polygon), right? – Rody Oldenhuis Jan 08 '14 at 07:34
  • Do the polygons you want to intersect lie in the same plane? If so, the output will be nothing, a point, or a polygon. If not, the output will be nothing, a point, or a line segment. – Rody Oldenhuis Jan 08 '14 at 07:36

  • Ya the polygons lie in the same plane.But in order to use the polybool function in MATLAB it needs all points on the two surfaces.Hence I wanted to convert the patch between 4 points to a surface with points on the patch surface. – Nagsaver Jan 08 '14 at 07:51

    [This question](http://stackoverflow.com/questions/7915734/intersection-and-union-of-polygons) might also be useful. – Rody Oldenhuis Jan 08 '14 at 07:55
  • I finally got it.Using polybool function with patch only works.Thanks – Nagsaver Jan 08 '14 at 08:05
