    Abstract: An online virtual experiences server generates a first instance of a virtual experience that is associated with a first client device. The server receives a request from the first client device to initiate a video call with a second client device. The video call is displayed as a user interface that includes a first avatar associated with the first client device and a second avatar associated with the second client device. Responsive to the second client device joining the video call, the server generates a second instance of the virtual experience. The first client device and the second client device teleport to the second instance of the virtual experience. The server receives a confirmation from the first client device and the second client device that the video call is hosted by the second instance of the virtual experience. The confirmation includes an identification of eligible participants for the video call.

    Abstract: Rigid accessory adjustment provides dynamic manipulation of accessories, such as clothing items, headgear, weapons, and ornaments, attached to virtual game three-dimensional (3D) avatars. The rigid accessories maintain a constant shape, allowing players to fine-tune the position, rotation, and scaling of accessories. An accessory adjustment tool is used for fitting or styling of rigid accessories on 3D avatars, including changing position, rotation, and scaling of the rigid accessories. The rigid accessory adjustment include providing an avatar in a 3D virtual environment, providing a rigid accessory for the avatar body, performing at least one adjustment from the group comprising adjusting a position, adjusting a rotation, and adjusting a scale of the rigid accessory relative to the avatar body, and animating the avatar body, wherein the rigid accessory animates in correspondence with the animated avatar body.

    Abstract: Real-time extraction of human poses from video data for animation of avatars. In some implementations, a computer-implemented method includes obtaining an input video including a plurality of video frames in a sequence that depict movement of a person based on a plurality of poses of the person in the input video. Keypoints of the person are detected in the video frames of the input video data, and a sequence of 3D body poses are determined that correspond to the plurality of poses of the person in the video frames of the input video. Determining the 3D body poses includes using a spatial-temporal transformer to determine joint angles of the keypoints, where the spatial-temporal transformer separately encodes inputs in spatial dimensions within each video frame and a temporal dimension across the video frames.

    Abstract: Layered clothing (LC) may be fitted on a three-dimensional (3D) avatar for a virtual experience. Some implementations relate to methods, systems, and computer-readable media to perform validation checks to check the quality (such as correctness and functionality) of the layered clothing. In some implementations, the method includes performing at least one static validation check on the clothing item to validate the clothing item when layered over an underlying surface, based on at least one property of the clothing item from the group comprising: an inner cage of the clothing item, an outer cage of the clothing item, a reference mesh of the clothing item, and combinations thereof; and in response to detecting at least one failure result from the at least one static validation check, providing an identified issue based on the at least one static validation check having the at least one failure result.

    Abstract: Some implementations relate to methods, systems, and computer-readable media to fit a clothing item onto an avatar body in a three-dimensional environment. To obtain a more tailored/precise fitting, dimensions of the clothing item are constrained according to various reference dimensions. A reference region for the avatar body is identified along with a reference dimension. A first region of a clothing item is identified, the first region having a first dimension. At least one second dimension of the clothing item is identified, and at least one first relationship between the first dimension and the second dimension is determined. The first dimension is changed to correspond to the reference dimension and the at least one second dimension is changed to scale the clothing item along the at least one second dimension, wherein the at least one first relationship is maintained after the changing of the at least one second dimension.

    Abstract: 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.

    Abstract: Extraction of human poses from video data for animation of computer models. In some implementations, a computer-implemented method includes determining a first pose sequence of a human body model based on frames of an input video, the frames depicting movement of a person. The first pose sequence includes poses of the human body model that correspond to the video frames. The first pose sequence is updated to produce a second pose sequence, including, over multiple iterations, determining joint velocities of joints of the pose sequence, determining, in parallel, predicted poses from each of multiple poses of the pose sequence by encoding the joint velocities into parameters of a human motion prior, and based on comparing corresponding predicted poses, adjusting joint angles of the pose sequence. The second pose sequence can provide an animation of a computer model corresponding to the movement of the person in the input video.
