I have a matrix of 512*512 points (x,y,z) and i have to reconstitute the 3d object. i thought to do like this : for each four points which form a square decompose into 2 triangles but it makes 511*511*2=522242 triangles. Is-it possible to display all them in a quick time? (because i have to rotate, zoom,light, applicate a photo of the real object on... the 3d object) Is it better to display 1 square in the place of 2 triangles? Is there another best method? (but not filter the points which contain not enough information and then make a DELAUNAY triangulation because the delaunay triangulation takes too many time) thx for response.
