Abstract: Surface relaxation techniques are disclosed for smoothing the shapes of three-dimensional (3D) virtual geometry. In one embodiment, a surface relaxation application determines, for each of a number of vertices of a 3D virtual geometry, span-aware weights for each edge incident to the vertex based on the alignment of other edges incident to the vertex with an orthonormal frame of the edge constructed using a decal map. The surface relaxation application uses such span-aware weights to compute weighted averages that provide surface relaxation offsets. Further, the surface relaxation application may restore relaxation offsets from an original to a deformed geometry by determining relaxation offsets for both geometries and transferring the relaxation offsets from the original to the deformed 3D geometry using a blending of the determined relaxation offsets and a rotation. In another embodiment, volume is preserved by computing relaxation offsets in the plane and lifting relaxed vertices back to 3D.

Abstract: Methods, systems, and articles of manufacture are disclosed for creating posed models. In various embodiments, deformations resulting from posing a model can be represented in a set of training poses. The sets of training poses for the model and a desired target pose (e.g., a simulated or sculpted pose) can be used to create a final pose for the model. Arbitrary deformer activation weights can be determined by projecting a target pose onto the set of training poses. The deformer activation weights can be applied to one or more deformers to approximate the desired pose.
