Abstract: In 3D rendering, shadows provide valuable visual information to viewers, and increase the level of realism in the rendering outcome. Therefore, shadow generation become a fundamental task in modern real-time rendering. Shadow mapping, one of the most common shadow generation techniques in real-time rendering, due to its inherent flaw is not capable of generating aliasing-free shadows. The irregular Z-Buffer algorithm revealed in 2004 eliminates the resolution mismatch problem in conventional shadow mapping, but it is not directly supported by the existing graphics hardware and lack of effcient software implementations. With the appearance of CUDA, the programmability of current graphics hardware has been drastically improved. It allows developers to leverage the enormous computation horsepower that resides in the current graphics hardware in a more flexible way. We provide a complete description to our irregular Z-Buffer based shadow mapping software implementation on CUDA. The rendering system we built is running completely on GPUs. It is capable of generating aliasing-free shadows at a throughput of dozens of million triangles per second.
