Generation of three-dimensional meshes of virtual characters

A non-transitory computer-readable medium with instructions stored thereon that, responsive to execution by a processing device, cause the processing device to perform operations comprising:

• obtaining a source three-dimensional (3D) mesh of a face of an avatar, wherein the source 3D mesh includes a first plurality of polygons;
• generating a second 3D mesh based on the source 3D mesh, wherein a count of polygons in the second 3D mesh is fewer than a count of polygons in the source 3D mesh;
• determining a two-dimensional (2D) parameterization of the second 3D mesh;
• determining a target 2D parameterization based on a template 3D mesh and the 2D parameterization of the second 3D mesh such that one or more landmarks identified in the source 3D mesh are aligned with corresponding landmarks on the template 3D mesh;
• and
• reconstructing the target 2D parameterization into a target 3D mesh.

A system comprising:

• a memory with instructions stored thereon;
• and
• a processing device, coupled to the memory, the processing device configured to access the memory and execute the instructions, wherein the instructions cause the processing device to perform operations comprising:
• obtaining a source three-dimensional (3D) mesh of a face of an avatar, wherein the source 3D mesh includes a first plurality of polygons;
• generating a second 3D mesh based on the source 3D mesh, wherein a count of polygons in the second 3D mesh is fewer than a count of polygons in the source 3D mesh;
• determining a two-dimensional (2D) parameterization of the second 3D mesh;
• determining a target 2D parameterization based on a template 3D mesh and the 2D parameterization of the second 3D mesh such that one or more landmarks identified in the source 3D mesh are aligned with corresponding landmarks on the template 3D mesh;
• and
• reconstructing the target 2D parameterization into a target 3D mesh.
