kleer001 Posted May 20, 2016 Share Posted May 20, 2016 Testing out an idea I had. Chop up A, Chop up B. Use the parts of B that are like A to rebuild A using only parts from B. 3D convolution. In audio the technique is called Convolution reverb. In Machine learning the technique is used to teach the computer to recognize objects. Here in my test it's used to glue a bunch of soggy corn flakes to the poor beleaguered Stanford terra cotta bunny. More explanation and demo videos to come. Questions? Comments? Has someone already done this but better? 2 Quote Link to comment Share on other sites More sharing options...
Skybar Posted May 20, 2016 Share Posted May 20, 2016 Interesting idea the video is less interesting though. Would be cool to see it build up, like this piece from mesh B goes here in mesh A -> up to completion. 1 Quote Link to comment Share on other sites More sharing options...
kleer001 Posted May 20, 2016 Author Share Posted May 20, 2016 Ayup, I was thinking along those lines for the demo/walkthrough. Right now I'm trying to get something that doesn't look like oatmeal mush. Maybe basing it just on normals and mean surface curvature isn't the best idea. I originally tried to do it in VDBs, but that borked out real quick. It'll probably be a little bit until I figure out what happens when you multiple a mesh by another mesh. Do you sort by normals? Do you sort by mean curviture? Do you use the bouding box? a simplified cage? [Armadillo] * [Rabbit] = [???] (teapot?) Quote Link to comment Share on other sites More sharing options...
MENOZ Posted May 21, 2016 Share Posted May 21, 2016 this is amazing 1 Quote Link to comment Share on other sites More sharing options...
kleer001 Posted May 22, 2016 Author Share Posted May 22, 2016 See, it should be possible. If people can do still-still and still-video we should be able to do 3d. Thinking now, I'm probably biting off more than I can chew with my 8 year old laptop. Anyone one else here with a big rig want to try their hand at it? Probably need to get TensorFlow working in Houdini... Quote Link to comment Share on other sites More sharing options...
