Here is an interesting demo of Video Trace<\/a>:<\/p>\n

I remember trying out technology along these lines sometime in 2000. In that program (the name escapes me now) you took pictures of a scene from different angles, and used the photographs as a guide when building polygons. My company was working on making virtual versions of a lot of real-world locales at the time, and were hoping this would be a time saver. It turned out the thing was very annoying and difficult to use. The software was so unwieldy that I decided we’d be better off doing the things the old-fashioned way. I loved the idea and wanted it to work, but it just wasn’t ready for prime time yet. It looks like the approach and the tools have been refined a great deal. <\/p>\n

What isn’t clear from the video is how the shadow underneath the truck is copied. The area of the shadow was not included among the modeled polygons. I also get the feeling that it’s a lot more work than it looks like in the video. I think a few steps were omitted. <\/p>\n

Also, the building in the second half of the video is the Sydney Opera House<\/a>. I had to make a 3d model of it sometime in 1999. It was a murderous project. (Unlike in the Video Trace demo, I was making something for realtime rendering and had to be very careful with polygon count and texture size. Those 1999 computers weren’t quite up to the job of handling curvy buildings like that one at a decent frame rate.) I didn’t have good photographs to work with, and my modeling skills were not up to the job. The end result wasn’t very good. It’s a very difficult building, and it’s great seeing the place done right in this demo. <\/p>\n","protected":false},"excerpt":{"rendered":"
