GDC 2009 Larrabee presentations availabe
The Larrabee presentations from the GDC are available now. Unlike the previous ones, these are finally technically interesting and describe how they implemented their recursive half-space based triangle rasterizer and how to port other algorithms to Larabee. Interesting read for sure, so grab it right away.
Update: There’s also a bunch more available on their GDC page. Definitely worth a look.
