Techniques relate to fitting a shape of an object when placed in a desired pose. For example, a plurality of training poses can be received, wherein each training pose is associated with a training shape. The training poses can be clustered in pose space, and a bid point can be determined for each cluster. A cluster-fitted shape can then be determined for a pose at the bid point using the training shapes in the cluster. A weight for each cluster-fitted shape can then be determined. The cluster-fitted shapes can then be combined using the determined weights to determine a shape of the object in the desired pose.

Pose-space shape fitting

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.

The disclosure provides an approach for stylizing animations to synthesize example textures. In one embodiment, a synthesis application down-samples input and style buffers. To obtain a sequence of offset fields, each of which takes pixels in the output stylized frame to corresponding pixels in the stylized example image, the synthesis application may optimize each frame of the animation at level l&#x2212;1, then advect the results of a previous frame to a next frame using velocity fields. After having processed the entire animation sequence forward through time, a similar sweep may be performed backwards. Then, the resulting offset fields may be up-sampled to level l and used as the starting point for optimization at that finer level of detail. This process may be repeated until returning to the original sampling, which yields the final output.
