Mecha Demo
The Mecha demo shows the results of a new approach to rendering semi-transparent objects without pre-sorting, known as order-independent transparency (OIT). It is made possible by the ATI Radeon™ HD 5800 Series of graphics processors and the new features of Microsoft® DirectX® 11 technology. Blending is an order-dependent operation that requires sorting objects before rendering them. Atomic operations and append buffers make it possible to construct per-pixel fragment lists and sort them on the GPU. The results are a significant increase in speed and accuracy over those possible with traditional techniques.
* The Mecha demo requires Windows 7® operating system, an ATI Radeon™ HD 5800 Series graphics processor, ATI Catalyst™ 9.9 or higher software, a dual- or quad-core CPU, and 2GB of RAM.
Ladybug Demo
The Ladybug demo shows the results of a new approach to simulating lens-accurate depth-of-field effects based on real-world parameters of focal length and focus distance. This technique is made possible by the ATI Radeon™ HD 5800 Series of graphics processors and the Microsoft® DirectX® 11 and Direct Compute 11 technologies. Depth-of-field is used in feature films by cinematographers to subtly guide a viewer’s attention through a shot or to heighten the emotion of a scene. This technique finally provides developers with a way to achieve the same effects and bring new levels of cinematic realism to their games. This approach is enabled by features such as atomic operations and shared memory.
