You are cordially invited to attend the OpenGL BOF on Wednesday 6-7pm in the Gold Ballroom in the JW Marriott hotel to celebrate 20 years of OpenGL with us. You’ll learn what is new and upcoming with the OpenGL API. We will also have two special guest speakers. Rich Geldreich from Valve will talk about their awesome project “Steam’d Penguins” that brings Steam and OpenGL games to Linux. Rich will be speaking about their challenges and successes porting Left 4 Dead 2 to OpenGL on Linux. Kurt Akeley, co-founder of SGI and of the OpenGL API will give his perspective on 20 years of OpenGL development. Right after the BOF we’ll open the doors for the OpenGL 20th anniversary party, with free drinks and various prizes to win. For more information, visit our Siggraph webpage.
