zveris Posted September 26, 2002 Share Posted September 26, 2002 hi, have a tough question: I have a sequence of geo files containing point cloud. Although the number of points in each geo is equal, the numbering of points is arbitrari. Now I have tryed to order them using sort op but didn`t get nowhere, the motion of points is bit too complex. anyone can think of any other way to order point numbering for animated sequence? thx in advance Quote Link to comment Share on other sites More sharing options...
danteA Posted September 26, 2002 Share Posted September 26, 2002 What's the underlying motivation for sorting the points? What's the effect that you want to accomplish? Quote Link to comment Share on other sites More sharing options...
zveris Posted September 26, 2002 Author Share Posted September 26, 2002 the motion of the points is used to drive deformations, like in mocap system, for example to copy creageons or drive magnet sops. anyway, if the numbering is wariating randomly during animation, so the deformers are jumping randomly, making it all useless Quote Link to comment Share on other sites More sharing options...
danteA Posted September 26, 2002 Share Posted September 26, 2002 Ah, sorry, I misunderstood your question. Have you tried sorting by distance from the centroid? Quote Link to comment Share on other sites More sharing options...
chang Posted September 26, 2002 Share Posted September 26, 2002 How about this strategy ? 1. bring in points of frame 1 and frame 2. 2. search closest fairs of two points. ( one must be on frame 1, the other is on 2 ) 3. now you have velocity. within range alpha and distance, search point of frame 3. 4. loop to 2 This is my first guess. I'll think about advanced one later. Quote Link to comment Share on other sites More sharing options...
