  • Patent number: 9892539
    Abstract: A method is disclosed for applying physics-based simulation to an animator provided rig. The disclosure presents equations of motions for simulations performed in the subspace of deformations defined by an animator's rig. The method receives an input rig with a plurality of deformation parameters, and the dynamics of the character are simulated in the subspace of deformations described by the character's rig. Stiffness values defined on rig parameters are transformed to a non-homogeneous distribution of material parameters for the underlying rig.

  • Patent number: 9519988
    Abstract: A method of animation of surface deformation and wrinkling, such as on clothing, uses low-dimensional linear subspaces with temporally adapted bases to reduce computation. Full space simulation training data is used to construct a pool of low-dimensional bases across a pose space. For simulation, sets of basis vectors are selected based on the current pose of the character and the state of its clothing, using an adaptive scheme. Modifying the surface configuration comprises solving reduced system matrices with respect to the subspace of the adapted basis.

  • Patent number: 9036898
    Abstract: High-quality passive performance capture using anchor frames derives in part from a robust tracking algorithm. Tracking is performed in image space and uses an integrated result to propagate a single reference mesh to performances represented in the image space. Image-space tracking is computed for each camera in multi-camera setups. Thus, multiple hypotheses can be propagated forward in time. If one flow computation develops inaccuracies, the others can compensate. This yields results superior to mesh-based tracking techniques because image data typically contains much more detail, facilitating more accurate tracking. Moreover, the problem of error propagation due to inaccurate tracking in image space can be dealt with in the same domain in which it occurs. Therefore, there is less complication of distortion due to parameterization, a technique used frequently in mesh processing algorithms.
