Patent number: 12190427Abstract: An automated cage-to-cage fitting technique is used to fit three-dimensional (3D) geometry to 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 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 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). 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.Type: GrantFiled: October 13, 2022Date of Patent: January 7, 2025Assignee: Roblox CorporationInventors: Sergei Makeev, Byungmoon Kim, Si Chen
