  10. 10. Order Independent Transparency (OIT)<br /><ul><li>Efficient rendering of many overlapping transparent objects
  11. 11. Smoke, fire, hair, foliage, fences, water, glass
  12. 12. Rendering transparent objects correctly requires sorting
  13. 13. Blending is an order dependent operation
  14. 14. DirectCompute 11 simplifies OIT by sorting transparent pixels in one shader pass
  15. 15. Uses atomic operations and append buffers</li></ul>9<br />

Tessellating the Right Way<br />Can add significant detail to a scene while effectively compressing geometry<br />But excessive use of tessellation can be inefficient for today’s GPUs<br />Poor utilization of rasterizers<br />Overshading<br />Too many polygon edges for MSAA<br />Brute force approach is wasteful<br />Overshade per pixel<br />8<br />7<br />6<br />5<br />4<br />3<br />21<br />25 pixel triangles<br />5 pixel triangles<br />1 pixel triangles<br />15 pixel triangles<br />16 pixel triangle<br />100% rasterizer utilization<br />1 pixel triangle<br />6.25% rasterizer utilization<br />
  25. 25. Morphological Anti-Aliasing<br />No AA<br />Morphological AA<br />Post-process filtering technique accelerated with DirectCompute<br />Delivers full-scene anti-aliasing<br />Not limited to polygon edges, alpha-tested surfaces, etc.<br />Faster than super-sampling<br />Performance similar to edge-detect CFAA, but applies to all edges<br />Compatible with any DirectX® 9/10/11 application<br />Including games with no AA support<br />Enabled via AMD Catalyst Control Center™<br />Images captured from Aliens vs. Predator by Rebellion<br />
