Techniques for generating stylized quad-meshes from tri-meshes

One or more non-transitory computer readable media including instructions that, when executed by one or more processors, cause the one or more processors to automatically modify a three-dimensional (3D) object design by performing the steps of:

• generating one or more shape constraints based on an input triangle mesh that represents the 3D object design and a preferred orientation associated with at least a portion of the input triangle mesh;
• generating a simplified T-spline based on the input triangle mesh, the one or more shape constraints, at least one mesh complexity constraint, and a quad generation algorithm;
• and
• performing one or more operations to crease one or more edges included in the simplified T-spline to generate a stylized T-spline, wherein the stylized T-spline represents a stylized design that is more convergent with the preferred orientation than the 3D object design.

A system for automatically modifying a three-dimensional (3D) object design, the system comprising:

• one or more memories storing instructions;
• and
• one or more processors that are coupled to the one or more memories and, when executing the instructions, are configured to:
• generate a simplified quad mesh based on an input triangle mesh that represents the 3D object design, a preferred orientation associated with at least a portion of the input triangle mesh, and at least one mesh complexity constraint;
• perform one or more operations to convert the simplified quad mesh to a simplified T-spline;
• and
• perform one or more operations to crease one or more edges included in the simplified T-spline to generate a stylized T-spline, wherein the stylized T-spline represents a stylized design that is more convergent with the preferred orientation than the 3D object design.
