Posted on Sunday, October 25 2009 @ 12:35 CET by Thomas De MaesschalckThe 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 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.
