Join Lee Howes, a Senior SDE at ATI/AMD, as he gives you a deep dive into GPU accelerated physics.

This lecture explains how DirectCompute can be employed to create solutions simulating physical systems such as fluid and cloth systems. It also covers how to employ some of the libraries powered by DirectCompute and how to integrate these libraries into your application. 

After completing the lecture, you will be able to understand the underlying algorithms of some of the physics systems written in DirectCompute, as well as how to make use of the libraries that implement them, such as Bullet.

For more information on DirectCompute, download the PDC 2009 DirectCompute HOLwatch the DirectCompute Roundtable discussion, see the full DirectCompute lecture series, and download the slides for this lecture.

      Excellent lecture on GPU Accelerated physics.

      that is awsome Smiley

      Neat, of course, but also terrifying in practice.


      Simple graphical HLSL programs are a painful to debug, even with great tools like PIX.


      Debugging this type of highly optimized code will be a nightmare. I'm not even sure how to write a reasonable unit test for this type of code. We can reason about the underlying machine and look at frame rates, but that's still comes short of the profiling capabilities we're used to on the CPU.


      Hopefully we'll start seeing more cores on the CPU so that we can keep doing our physics calculations there, where our development tools are sufficient.
