Inferred skeletal structure for practical 3d assets

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

• receiving an avatar data model for a three-dimensional (3D) avatar, the avatar data model comprising a plurality of different body parts including at least a first body part from a first parent 3D model and a second body part from a second parent 3D model;
• creating a graph representation for the avatar data model, wherein the graph representation has a root point for the avatar data model, extends to one or more terminal portions of the avatar data model, and comprises a plurality of nodes labeled according to corresponding body parts of the 3D avatar;
• traversing the graph representation to determine a plurality of joint locations of the 3D avatar, wherein the joint locations each represent a respective location where a joint is to be placed, wherein the joint locations are determined based on one or more of:
• intersections of two or more of the different body parts,
• descriptions of one or more of the different body parts, or
• connections between two or more of the different body parts,
• wherein at least one joint location of the plurality of joint locations represents an intersection between the first body part and the second body part;
• inferring a skeletal structure of the 3D avatar based on the plurality of joint locations;
• and
• combining joints at each of the plurality of joint locations, the inferred skeletal structure, and the avatar data model to create a 3D asset.

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 or control performance of operations comprising:
• receiving an avatar data model for a three-dimensional (3D) avatar, the avatar data model comprising a plurality of different body parts including at least a first body part from a first parent 3D model and a second body part from a second parent 3D model;
• creating a graph representation for the avatar data model, wherein the graph representation has a root point for the avatar data model, extends to one or more terminal portions of the avatar data model, and comprises a plurality of nodes labeled according to corresponding body parts of the 3D avatar;
• traversing the graph representation to determine a plurality of joint locations of the 3D avatar, wherein the joint locations each represent a respective location where a joint is to be placed, wherein the joint locations are determined based on one or more of:
• intersections of two or more of the different body parts,
• descriptions of one or more of the different body parts, or
• connections between two or more of the different body parts,
• wherein at least one joint location of the plurality of joint locations represents an intersection between the first body part and the second body part;
• inferring a skeletal structure of the 3D avatar based on the plurality of joint locations;
• and
• combining joints at each of the plurality of joint locations, the inferred skeletal structure, and the avatar data model to create a 3D asset.
