Embodiments provide for transferring mesh connectivity. Embodiments include receiving a definition of a correspondence between a first curve for a source mesh and a second curve for a target shape. Embodiments include initializing an output mesh by setting a third plurality of vertices in the output mesh equal to a first plurality of vertices in the source mesh. Embodiments include transforming the output mesh by modifying the third plurality of vertices based on the first curve, the second curve, and a second plurality of vertices of the target mesh. Vertices of the third plurality of vertices that relate to the first curve are conformed to a shape defined by the second curve, and vertex modifications that result in affine transformations of faces in the output mesh are favored. Embodiments include using the output mesh to transfer an attribute from the source mesh to the target shape.

Mesh wrap based on affine-invariant coordinates

Embodiments provide for sculpt transfer. Embodiments include identifying a source polygon of a source mesh that corresponds to a target polygon of a target mesh. Embodiments include determining a first matrix defining a first rotation that aligns a target rest state of the target polygon to a source rest state of the source polygon, determining a second matrix defining a linear transformation that aligns the source rest state to a source pose of the source polygon, wherein the linear transformation comprises rotating and stretching, determining a third matrix defining a second rotation that aligns the source pose to the target rest state, and determining a fourth matrix defining a third rotation that aligns the source rest state to the source pose. Embodiments include determining a target pose of the target polygon based on the target rest state, the first matrix, the second matrix, the third matrix, and the fourth matrix.
