When Cem Yuksel first started the Hair Farm project, the available technologies in Computer Graphics for modeling, animating, and rendering hair were very limited and under-developed for producing a hair software that would fully satisfy an artist. Therefore, while he was writing Hair Farm, he also got engaged in a number of research activities and proposed various novel technologies required for a solid hair modeling, animation, and rendering software.
After 6 years of research and development, he managed to solve the last piece of the puzzle with his invention of Hair Meshes. This novel hair modeling approach is presented in SIGGRAPH Asia 2009 in the Technical Papers session, among some of the top Computer Graphics research works being published this year.
Some of the novel technologies in Hair Farm are the following:
* An artist-friendly realistic hair material that can efficiently handle complicated light behavior like multiple scattering in hair volume to produce physically-based realism,
* A highly optimized high-quality ray tracer for hair that automatically handles anti-aliasing without the need to specify the number of samples,
* A whole new hair simulation technique that can robustly handle complicated models and advanced physical behavior like hair-hair interaction,
* Technologies in curve representations for modeling and rendering.
