Some implementations relate to methods, systems, and computer-readable media for inferring a skeletal structure to create a practical 3D asset. A user may create an avatar using different parts from different parent models. Upon creation, a data model for the avatar is examined to determine joint placement and infer an overall skeletal structure. Thereafter, different skinning techniques may be used to deform the avatar skin during animations based on the joint placement and movement.

Inferred skeletal structure for practical 3D assets

An automated cage-to-cage fitting technique is used to fit arbitrary three-dimensional (3D) geometry to arbitrary target 3D geometry for 3D avatars in a 3D environment, such as an online game. Each graphical representation of items of clothing is provided with an inner cage and with an outer cage. The inner cage of a clothing item (a current layer) is mapped to the outer cage of another clothing item (a previous/underlying layer) that has already been fitted on the 3D avatar. This mapping enables the current layer to conform to the shape of the previous layer. The technique allows any body geometry to be fitted with any clothing geometry, including enabling layers of clothing to be fitted over underlying layer(s) of clothing, thereby providing customization.

This mapping enables the current layer to conform to the shape of the previous layer. The technique allows any body geometry to be fitted with any clothing geometry, including enabling layers of clothing to be fitted over underlying layer(s). Hidden surface removal (HSR) operations may be performed to identify surfaces of an underlying layer that are hidden by an overlying layer, and such hidden surfaces are not rendered.
