Five Steps to Adding Physics-Based Realism

Posted by timothy on from the pang-zoom-and-whingo dept.

Lisa writes: "Colliding billiard balls. Missile trajectories. Cornering dynamics in speeding cars. If these type of actions are expressed in computer software, applying physics-based models can greatly enhance the level of realism. David M. Bourg offers five steps towards doing just that in this LinuxDev Center article."

    It's just maths.

    But this seems like an advertisement for another O'Reilly book. This is the second such advertisement here on the Developers section in as many days.

    What's going on?

    What about the physics in movies such as Final Fantasy? The character detail was very well done, but the physics of their motions and mouth movements were terrible. I think that more attention needs to be put into making the physics more organic than increasing the polygon count.

      I thought the physics was fairly good. FYI, their motions were done by having actors perform the motions, and they mapped the cgi motions to the recorded human motions. Blame the actors if you don't like it, I suppose. Their speech motions aren't perfect, but they were better than I've seen anywhere else.

      Compare Monsters Inc. to FF. The mouth movements for Monsters was infinitely better than FF's.

      Not all of the motion was done using actors though. The speech for example was hand animated for each sound they made. I thought this looked horrible compared to other motion in the movie. Information on how they did it was included on the DVD version of Final Fantasy. It's a bit long to watch, but interesting.

      But did they speak Japanese in the movie originally...?

    Crud! Why couldn't this book have come out 5 years ago when I was actually doing game development? Oh well, at least Chris Hecker's physics articles in Game Developer came at the right time.

    BTW, if anyone happens to see a Simpsons Bowling arcade machine in the Chicago area, let me know where. I'd love to see if my physics model made it into the final production.

    I give up on debugging. From now on, SIGSEGV is a feature.

    Has anyone tried Dynamo?
