Hunting down some problems with the performance in the pose filtering some quite essential change needed to be introduced: fully pipelined tracking.

As in any good pipeline the tracking is queued between two important timing steps:

• the capturing camera has finished a frame update including color space conversion
• the render buffer wasn't swapped yet

Result of this pipeline is a tremendous performance boost. Every millisecond counts - and for what I am doing now squeezing the whole tracking process (including capture, color conversion etc. pp) to lower than 2ms per frame on a standard MacBook is essential. Beside that, ISMAR deadline is approaching fast - well it was just moved. After the ISMAR paper deadline I will publish SSTT visualizer 2.0 - stay tuned!
