US 2022/0284677 A1 · DEFORMATION WITH META-HANDLES OF 3D MESHES

Abstract

This disclosure includes technologies for deformation of 3D shapes using meta-handles. The disclosed 3D conditional generative system takes control points with biharmonic coordinates as deformation handles for a shape to train a network to learn a set of meta-handles for the shape. Further, each deformation axis of the latent space of deformation is explicitly associated with a meta-handle from a set of disentangled meta-handles, and the disentangled meta-handles factorize plausible deformations of the shape. Advantageously, an intuitive deformation of the shape may be generated by manipulating coefficients of the meta-handles, e.g., via a user interface.

Dependent claims

One or more computer storage media storing computer-useable instructions that, when used by one or more processors, cause the one or more processors to perform operations comprising:

receiving a source three-dimensional (3D) shape and a target 3D shape;
determining control points on the 3D shape and biharmonic coordinates for the control points;
and
training a network to learn a set of meta-handles for the source 3D shape and a coefficient range for each meta-handle, each meta-handle corresponding to a combination of control-point offsets, the network including:
a meta-handle network that determines the set of meta-handles and coefficient ranges based on the source 3D shape, the control points, and the biharmonic coordinates;
and
a deformation network that determines coefficient values for the meta-handles that generate a resulting deformation of the source 3D shape to match the target 3D shape.

A computer-implemented method, comprising:

training a model to learn a set of meta-handles for a three-dimensional (3D) shape and a coefficient range for each meta-handle based on control points on the 3D shape and biharmonic coordinates of the control points, each meta-handle corresponding to a combination of control-point offsets;
receiving, via a graphical user interface, an indication of a deformation degree associated with at least a portion of the set of meta-handles;
determining at least one coefficient value for the set of meta-handles based on the deformation degree;
and
generating a deformed shape from the 3D shape based at least in part on the determined at least one coefficient value for the set of meta-handles.
