The actual movement of your skin surface is driven by the structures within your hand such as bones, muscles, skin, tendons, and fat. These movements are subtle, but if they're wrong, you'll notice them– our brains are so attuned to what natural movement looks like that any tiny imperfections shout that it's fake.
Weta Digital's Academy Award Winners share their revolutionary simulation technology.
Tissue takes the opposite approach, going from the inside out. Artists create a detailed skeleton, then layer on muscles, fascia, and fat. Then, as the character moves, Tissue calculates how this anatomy would move in the real world – and drives the skin deformation based on that. Animators still control the main movements, but the subtle skin motions happen automatically. Tissue has been used on every film since Avatar. In 2013, it won a Scientific/Technical Oscar.
Simon Clutterbuck and James Jacobs, along with Dr. Richard Dorling, developed the linear-elastic finite-element system 'Tissue' to build muscles, skin, and fat for creatures in such films as Avatar, Rise of the Planet of the Apes, Prometheus and The Hobbit: An Unexpected Journey.
To Simon Clutterbuck, James Jacobs and Dr. Richard Dorling for the development of the Tissue Physically–Based Character Simulation Framework. This framework faithfully and robustly simulates the effects of anatomical structures underlying a character's skin. The resulting dynamic and secondary motions provide a new level of realism to computer–generated creatures.
