A high-end rendering technique that was previously only availble on workstations (and even then very slowly!) is coming to your phones
This is a very successful attempt to build a system that can simulate walking with all types of two-legged characters. It's extremely funny as well!
Will we ever have completely digital actors intermingling with real ones? Will we soon have feature films where dead actors are brought back to life through the miracle of CGI and motion capture? Will computer generated images of humans ever be so good that we can't distinguish them from the real thing in any way?
Pixar's new animation system allows animators to visualise their characters with all the important detail visible. Like hair!
Have a close look at this video clip. It’s an advert for a high-end kitchen worktop manufacturer. Watch it in 720p, and look as closely as you can at the camerawork, the clever use of depth of field, the lighting, and particularly the fresh fruit.
And then reflect on the fact that no cameras - or indeed fruit - were involved in the making of this at all.
