(Source: forums.cgsociety.org) [Demo video below]  There were many drawbacks to traditional texture mapping methods that led to the development of Ptex:

  • UV assignment was a tedious task, and making good UVs on complex models was difficult.
  • Texture seams could produce visible artifacts especially with displacement maps.
  • Large numbers of texture files were required creating a significant I/O bottleneck.

Ptex addresses all these issues by eliminating UV assignment, providing seamless filtering, and allowing any number of textures to be stored in a single file.

Dr. Terrile is the director of the Center for Evolutionary Computation and Automated Design at NASA’s Jet Propulsion Laboratory.

Terrile uses techniques based on biological evolution and development to advance the fields of robotics and computer intelligence. He has a Ph.D. in Planetary Science from the California Institute of Technology and has developed missions to Mars and to the outer solar system. Terrile’s other areas of expertise include the development of medical instrumentation for neurosurgery and the study of planetary rings and geology. He has discovered four moons and is the first to photograph another solar system.

(Source: Variety.com) Not long ago I got a call from a Time magazine reporter working on a story on the visual effects business. As we discussed the dire financial straits of many vfx companies despite their growing importance to studio movies, she asked, “Don’t these people have business plans?”

I told her she was proceeding from the false premise that people start vfx companies to be business owners. Most people who go into vfx do it for the same reason people become actors: They love the work. But when they fail as businessmen, the result is too often misery.
