In 6 Days to Air, the documentary about the making of South Park, there is some great footage of the animators working on the characters in studio on wacom tablets. I couldn't tell what program it was. Does anyone know if it is a proprietary suite or something that can be purchased?
From the Wikipedia article on South Park:
When the show began using computers, the cardboard cutouts were scanned and re-drawn with CorelDRAW, then imported into PowerAnimator, which was used with SGI workstations to animate the characters. The workstations were linked to a 54-processor render farm that could render 10 to 15 shots an hour.
Beginning with season five, the animators began using Maya instead of PowerAnimator. The studio now runs a 120-processor render farm that can produce 30 or more shots an hour.
