A brief introduction to 3D

With WebGL and Molehill around there is a new playground for us flash developers. First I felt a bit stressed over the fact that I have to compete with people doing this for years on the desktop, consoles, mobiles and with plugins like Unity. But it’s just a good thing. There is loads of information and knowledge around waiting for us to consume. We can cut to the chase and use the techniques developed by people before us. We are also several years left behind cutting edge 3D regarding performance and features, so the 3D community have produced loads of forum-threads, tutorials and papers. It will be interesting to see how the flash community will embrace this “new” technique. Games is a obvious field, but what about campaigns and microsites?

Some days ago I had the opportunity to hold a presentation about 3D basics. My goal was to give a overview of topics that could be good to look into as a starter. I have tried to pick them from the perspective of a “online developer”, with MolehillWebGL and Unity as a foundation. The word-cloud above show some of the words I put into context.  It’s basic stuff, in keywords and bullet-lists, so think of this as a dictionary of topics to find more information about on your own. There is some cool demos and resources in there as well. If you are into 3D programming already, this is probably not so interesting for you though, instead you can help me review the slides and point out possible improvements ;).

Here is the presentation as PowerPoint (16 MB, with fancy transitions and animations) and pdf (6 MB, not so fancy but comments are more visible). If you don’t have PowerPoint installed you can  just download PowerPoint viewer here instead.

Important topics missing? Thing I got wrong? I would love to hear some feedback on things to improve.

  1. I saw the presentation and it all look great…
    I wish that I could listen to you while you present these things…

  2. I’d argue that transformation matrices themselves are actually memory efficient, and are actually CPU intensive, not memory intensive, but when you have a huge number of vertices, and do some matrix multiplications on such a huge set, I agree that they could become memory hogs.

    I found a couple of typos, and I think that the accompanying image for orthographic projection is not accurate, but apart from that, I think that in overall it’s a good overview of 3d in general.

    It’s a nice and informative presentation. Thanks for sharing.

  3. Thanks for reading and commenting! This slides/presentation was from my first attempt to grasp the world of 3D, so I guess many things could be done better today.
