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

A method may include causing first content to be displayed on a display device; causing second content to be rendered irrespective of a location of a mobile device relative to the display device; and causing the second content to be displayed on the mobile device such that the second content is layered over the first content. When the second content has moved a predetermined distance from the screen, The method may also include causing the second content to be rendered based on the location of the mobile device relative to the display device; and causing the second content to be displayed on the mobile device such that the second content is layered over the first content.

Content presentation and layering across multiple devices

A method may include capturing a first image of a physical environment using a mobile device. The mobile device may include a physical camera and a display. The method may also include receiving a second image from a content provider system. The second image may be generated by the content provider system by rendering a view from a virtual camera in a virtual environment. The virtual environment may represent at least a portion of the physical environment. A location of the virtual camera in the virtual environment may correspond to a location of the physical camera in the physical environment. The second image may include a view of a computer-generated object. The method may additionally include generating a third image by compositing the first image and the second image, and causing the third image to be displayed on the display of the mobile device.

Compositing images for augmented reality

A method may include causing first content to be displayed on a display device. The method may also include determining a location of a mobile device relative to the display device. In some embodiments, the mobile device may be positioned such that the first content is visible to a viewer of the mobile device. The method may additionally include causing second content to be displayed on the mobile device such that the second content is layered over the first content.

A method may include rendering a first view of a three-dimensional (3-D) virtual scene comprising a view of first content being displayed on a virtual display device from a location in the 3-D virtual scene. The method may also include rendering a second view comprising one or more content objects. The second view may be rendered from the location in the 3-D virtual scene, and the second scene may include a view of the display device as would be seen through a pair of augmented-reality glasses that display the one or more content objects. The method may additionally include generating a composite view by combing the first view and the second view. The method may further include causing the composite view to be displayed on a virtual-reality headset.

Augmented reality simulation

Methods, systems and computer program products pertaining to simulating liquid bodies are presented. The subject matter of this document can be embodied in a method that includes obtaining one or more data arrays representing low frequency spatial features of a simulated volume of liquid, and up-sampling the one or more data arrays to produce corresponding high resolution data arrays. The method also includes obtaining procedural data representing high frequency spatial features of a simulated liquid surface, and modifying the one or more high resolution data arrays using the procedural data to produce corresponding modified data arrays that reflect both the high frequency and the low frequency spatial features of the simulated volume of liquid.

High resolution simulation of liquids

A method may include presenting a scene from linear content on one or more display devices in an immersive environment, and receiving, from a user within the immersive environment, input to change an aspect of the scene. The method may also include accessing 3-D virtual scene information previously used to render the scene, and changing the 3-D virtual scene information according to the changed aspect of the scene. The method may additionally include rending the 3-D virtual scene to incorporate the changed aspect, and presenting the rendered scene in real time in the immersive user environment.

Real-time content immersion system

Methods are disclosed for the computer generation of data for images that include hair, fur, or other strand-like material. A volume for the hair is specified, having a plurality of surfaces. A fluid flow simulation is performed within the volume, with a first surface of the volume being a source area through which fluid is simulated to enter the volume, and a second surface being an exit surface through which fluid is simulated as exiting the volume. The fluid flow simulation may be used to produce fluid flow lines, such as from a velocity vector field for the fluid. Fluid flow lines are selected, and image data of hairs that follow the fluid flow lines are generated. Other embodiments include generating animation sequences by generating images wherein the volume and surfaces vary between frames.

Styling of computer graphics hair through volumetric flow dynamics

A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes defining a simulated fluid object that includes a first portion and a second portion being represented by a signed distance function. The method also includes applying at least one constraint to the first portion of the simulated fluid object to match a velocity of a target. The method also includes applying a collection of calculated forces to the second portion of the simulated fluid object. Also, the method includes rendering the first portion applied with the at least one constraint and the second portion applied with the collection of calculated forces to present the simulated fluid object.

Simulating fluid structures

A computer-implemented method for simulating a granular material includes removing, from a layer of granular material in a virtual domain defined by a data structure stored in a computer readable storage medium, a portion of the granular material in a closed region where the portion and a part of an object impacting the granular material are defined as occupying a same space. The method includes determining a value for a size aspect of the portion based on applying a numerical solver along an entirety of a boundary of the closed region. The method includes placing additional granular material along the boundary to create a shape resulting from the impact of the object. The method includes generating an image using the data structure, the image reflecting the impact of the object on the granular material in the virtual domain.

Simulating granular material

The movement of elements through a region of three dimensional (3D) space is simulated by utilizing a number of two dimensional (2D) grids to define the region of 3D space. Movement information is associated with each grid point of each 2D grid, and changed over a time period. For each element in 3D space, movement information is interpolated from the grid points of a pair of 2D grids that lie on opposite sides of the element. The interpolated movement information is used to advect the elements through the region of 3D space.
