An immersive content presentation system and techniques that can detect and correct lighting artifacts caused by movements of one or more taking camera in a performance area consisting of multiple displays (e.g., LED or LCD displays). The techniques include capturing, with a camera, a plurality of images of a performer performing in a performance area at least partially surrounded by one or more displays presenting images of a virtual environment. Where the images of the virtual environment within a frustum of the camera are updated on the one or more displays based on movement of the camera, and images of the virtual environment outside of the frustum of the camera are not updated based on movement of the camera. The techniques further include generating content based on the plurality of captured images.

Immersive content production system with multiple targets

In one general aspect, a method is described. The method includes generating a positional relationship between one or more support structures having at least one motion capture mark and at least one virtual structure corresponding to geometry of an object to be tracked and positioning the support structures on the object to be tracked. The support structures has sufficient rigidity that, if there are multiple marks, the marks on each support structure maintain substantially fixed distances from each other in response to movement by the object. The method also includes determining an effective quantity of ray traces between one or more camera views and one or more marks on the support structures, and estimating an orientation of the virtual structure by aligning the determined effective quantity of ray traces with a known configuration of marks on the support structures.

Three-dimensional motion capture

A handheld device includes: an input control configured to control and modify a virtual scene including a virtual camera; and a display that shows a representation of the controlled and modified virtual scene generated by the virtual camera. A system includes: a computer system configured to execute program instructions for generating a virtual scene including a virtual camera; and handheld device configured to communicate with the computer system for controlling and modifying the virtual scene, the handheld device comprising: an input control configured to control and modify the virtual scene; and a display that shows a representation of the controlled and modified virtual scene generated by the virtual camera.

Virtual-scene control device

A method of motion capture may include accessing a 3D model of a subject, and associating the 3D model of the subject with a 2D representation of the subject in a plurality of frames. The method may also include identifying a change to the 2D representation of the subject between two or more of the plurality of frames, and deforming the 3D model in a virtual 3D space. In some embodiments, the deforming may be based on the identified change to the 2D representation and at least one constraint restricting how the 3D model can be deformed.

Geometry tracking

Among other aspects, on computer-implemented method includes: receiving at least one command in a computer system from a handheld device; positioning a virtual camera and controlling a virtual scene according to the command; and in response to the command, generating an output to the handheld device for displaying a view of the virtual scene as controlled on a display of the handheld device, the view captured by the virtual camera as positioned.

Controlling a virtual camera

In one aspect, a computer implemented method of motion capture, the method includes tracking the motion of a dynamic object bearing a pattern configured such that a first portion of the patterns is tracked at a first resolution and a second portion of the pattern is tracked at a second resolution. The method further includes causing data representing the motion to be stored to a computer readable medium.

Scale independent tracking pattern

A system includes a visual data collector for collecting visual information from an image of one or more features of an object. The system also includes a physical data collector for collecting sensor information provided by at one or more sensors attached to the object. The system also includes a computer system that includes a motion data combiner for combining the visual information the sensor information. The motion data combiner is configured to determine the position of a representation of one or more of the feature in a virtual representation of the object from the combined visual information and sensor information. Various types of virtual representations may be provided from the combined information, for example, one or more poses (e.g., position and orientation) of the object may be represented.

Visual and physical motion sensing for three-dimensional motion capture

A virtual director's viewfinder includes: a housing with a form factor of a director's viewfinder; at least one mechanical viewfinder control connected to the housing, the virtual director's viewfinder encoding a setting of the mechanical viewfinder control into digital setting information; at least one communication device for communication of the digital setting information to a computer system, and for receiving from the computer system an image generated using the digital setting information; and a display device that presents at least the image received from the computer system.
