Methods and systems for scalable skinning of three-dimensional (3d) objects

A system comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the processor to perform operations comprising:
• identifying data associated with a bone structure and a mesh for rendering a three-dimensional (3D) object, wherein the identified data comprises, for each vertex of the mesh, an indication of a set of bones of the bone structure assigned to the vertex and a weight for each bone of the assigned set of bones;
• determining that a number of bones included in a first set of bones assigned to a first vertex of the mesh satisfies a first bone number criterion;
• identifying, from the first set of bones, a first subset of bones and a second subset of bones, wherein the weight of each of the first subset of bones satisfies a weight condition, and wherein a number of bones of the first subset of bones satisfies a second bone number criterion;
• and
• transmitting, to a rendering engine, data associated with the first subset of bones as skinning data for rendering 3D objects and the second subset of bones as one or more other types of data for rendering the 3D objects.

A system comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the processor to perform operations comprising:
• receiving, using a rendering engine, first data associated with rendering a three-dimensional (3D) object via a first data channel and second data associated with rendering the 3D object via a second data channel, wherein the first data channel is associated with skinning data for rendering 3D objects and the second data channel is associated with one or more other types of data for rendering 3D objects;
• determining, using the rendering engine and based on the first data received via the first data channel, a first set of bones of a bone structure for the 3D object, the first set of bones assigned to a vertex of a mesh associated with the 3D object;
• determining, using the rendering engine and based on the second data received via the second data channel, a second set of bones of the bone structure, the second set of bones assigned to the vertex of the mesh associated with the 3D object;
• and
• rendering, using the rendering engine, at least the vertex of the mesh for the 3D object based on the determined first set of bones and the determined second set of bones.
