Judging will be based on these criteria;

(1) Use multiple PhysX features

The feature demos should focus on the effect they are trying to demo - for example a "fluids" demo needs to showcase what fluids can do. It's fine to have extra effects included but they should not be the main focus of what's being demonstrated. The Über demo is required to use all core PhysX features: fluids, force fields, soft & rigid bodies.

(2) Scalable demo

All demos must be scalable to show performance on different machine setups. See the example demo that shows an example of how to scale your demo. To have a chance of winning a prize your demo must scale well, so make sure you build in controls for adding more complexity to your demo scene. NVIDIA want to showcase how well PhysX works on a GeForce compared to the CPU.

(3) The demos should visually look great

Ensure your demo looks great, visualization will be an important part of the judging. We have supplied some free models to get you started but you'll have a better chance of winning if you add in your own content.

(4) User Interaction

User interaction is what makes physics simulation come alive, creative ways to allow the user to change or interact with the demo environment is very important. Having an option for the demo to loop around in stand alone environment would be considered very useful, but think about how to leverage the fact there are real physics simulations to make each run different from the previous one, when in a loop.

(5) Keep to the maximum demo size

If your feature demo exceeds the maximum size it will be rejected. So make sure you fit within the sizes specified.

(6) Maintain a work in progress thread

We recommend you create a thread within the TGC forums showcasing your demo work. TGC and NVIDIA will then actively feedback to you during the competition which will ensure you have a better chance of winning.
