This is Alf Lovvold’s Dawn Of The Planet Of The Zombies And The Killer Plants On Some Serious Acid, a tasty trailer done by just one guy. Check out his interview in 3DArtist for an idea of how he went about creating this.
This introduction to the SIGGRAPH convention experience starts with a practical guide to organizing to attend any large convention. He uses the same techniques many of us developed going to Comic Con or any other large Sci-Fi or Anime convention, but without having to go through three or four conventions gradually learning through trial and error how to organize your time and map out the convention space. So I recommend anyone who wants to attend a large convention watch the first 10 or 12 minutes of this presentation. He then goes on to break down the process of computer animation into its component parts by type of activity, giving a very clear understanding of how it works. If you have any interest in creating your own animations this is a great introduction. That shouldn’t be a surprise, since ACM SIGGRAPH is the Association of Computing Machinery’s Special Interest Group, GRAPHics which started life as an organization in 1967, held its first convention in 1974, and became an Internet NEWSGROUP back in the early 70s as well. The latest convention, coming up at the Los Angeles Convention Center the 9th through 13th of August, 2015, will be the 42nd time the event has been held.
