the hobbit :D

After reading an article of the movements of gollum etc. I've learned that in order to capture these motions and facial expressions and actor must wear a skin tight suit with infrared lights on them, they must be bright enough so the camera can pick them up in broad day light. This technique isn't used just on gollum but the goblins, orcs, and trolls from both "The Lord Of The Rings" and "The Hobbit". Ive also learned that peter jackson is taking the approach with 48 frames per second rather than 24. I n my opinion this article has showed me how the whole motion capturing system works. i especially like the illustration in the beginning of the article. How will motion capturing be further advanced?
