According to one report, Apple will have a "huge" presence at Siggraph this year.
Siggraph 2004 is "the 31st international conference on computer graphics and interactive techniques". The conference takes place between August 8-12, 2004 in the Los Angeles Conference Center in Los Angeles, California.
Last year, while Apple had a "strong" presence at Siggraph 2003, they did not hold an official booth... This year Apple is reported to have one of the largest (booth) presences of any vendor in the show.
