CGI in films

In avatar I think the imagery is absolutely amazing. It is done using a special motion capture suit with head rigs equipped with standard definition cameras that take constant images of the actors face. Those images are transmitted to another camera which creates a real time image of the live actor wearing their costume (how the character looks in the film)

You can see the stages a bit better in this image from Pirates of the Caribbean. From the human with the motion capture on his face to the simplified version of the character to the final version with all the details, but as you can see from the original image, they didn't use a camera on this one, maybe that is how James Cameron got his movements some great!!

This is a massive potential because if you think this was created in 2009 that was 6 years ago now, I wonder what other amazing things they can do in the next 10 years! The 3D on this was fabulous too! When I watched it in the cinema I was amazed at how far technology has come since spy kids 3D.There was no fuzziness and blue and red lines, just really clear 3D images that literally felt like they were coming out at you!!
