Abstract: A cloud-centric platform is used for generating virtual three-dimensional (3D) content, that allows users to collaborate online and that can be connected to different software tools (applications). Using the platform, virtual environments (e.g., scenes, worlds, universes) can be created, accessed, and interacted with simultaneously by multiple collaborative content creators using varying content creation or development applications.

Abstract: Approaches presented herein provide for the management of owned digital assets. An entity may obtain ownership of (or other rights to) a unique digital asset, and information regarding this ownership can be stored to a trusted registry, such as a blockchain. The only true copy of this digital asset is stored to a secure environment, with no identical copy of this digital being available outside this secure environment. A party may be able to obtain a copy, version, or view of this digital asset that will differ in at least some way from the true asset. For a 3D model asset, this may include providing only a 2D image of that 3D model that was rendered in a secure environment. In this way, a true reconstruction of the 3D model will be unable to be generated outside of the secure environment. If the asset was obtained through procedural generation, information about the generation (and ownership of one or more aspects of that generation) may be stored to the registry as well.

Abstract: A content management system may maintain a scene description that represents a 3D virtual environment and a publish/subscribe model in which clients subscribe to content items that correspond to respective portions of the shared scene description. When changes are made to content, the changes may be served to subscribing clients. Rather than transferring entire descriptions of assets to propagate changes, differences between versions of content may be exchanged, which may be used construct updated versions of the content. Portions of scene description may reference other content items and clients may determine whether to request and load these content items for lazy loading. Content items may be identified by Uniform Resource Identifiers (URIs) used to reference the content items. The content management system may maintain states for client connections including for authentication, for the set of subscriptions in the publish/subscribe model, and for their corresponding version identifiers.

Abstract: Approaches presented herein provide for automatic generation of representative two-dimensional (2D) images for three-dimensional (3D) objects or assets. In generating these 2D images, a set of options is determined such as may relate to viewpoint or other parameters of a virtual camera. A set of sample points is determined from which to generate 2D images of a 3D model, for example, with 2D images being processed using a classifier to determine which of these images generates a classification with highest confidence or probability, individually or with respect to other classifications. The sample point for this selected image can then be used to select nearby sample points as part of a refinement or optimization process, where 2D images can again be generated and processed using a classifier to identify a 2D image with highest classification probability or confidence, which can be selected as representative of the 3D object or asset.

Abstract: A content management system may maintain a scene description that represents a 3D world using hierarchical relationships between elements in a scene graph. Clients may exchange delta information between versions of content being edited and/or shared amongst the clients. Each set of delta information may be assigned a value in a sequence of values which defines an order to apply the sets of delta information to produce synchronized versions of the scene graph. Clients may follow conflict resolution rules to consistently resolve conflicts between sets of delta information. Changes to structural elements of content may be represented procedurally to preserve structural consistency across clients while changes to non-structural elements may be represented declaratively to reduce data size. To store and manage the content, structural elements may be referenced using node identifiers, and non-structural elements may be assigned to the node identifiers as field-value pairs.

Abstract: An augmented reality system and method of operating the same is provided. An end user is allowed to visualize direct light from a three-dimensional scene in an ambient environment, generating virtual image data from the point of the view of the end user. A region of spatial overlap between a real object in the three-dimensional scene and a virtual object in the virtual image data is determined. Color characteristics of the real object in the overlap region are determined. A perceived contrast between the real object and the virtual object in the overlap region is decreased based on the determined color characteristics of the real object in the overlap region. The virtual image data is displayed as a virtual image after the perceived contrast between the real object and the virtual object has been decreased that, along with the visualized direct light, creates a three-dimensional augmented scene.

Abstract: User interface display layouts are provided that draw a user's attention to a specific element or elements by de-emphasizing the surrounding content, but without removing the de-emphasized content from the interface. This ability to maintain the whole presentable layout with visibility layers and without layout changes provides a useful navigation experience for the user as it is clear where the user's attention should go and yet the surrounding content is still subtly there, constantly reminding the user of the other available content. De-emphasis of certain content items is achieved by modifying display characteristics of those content items relative to a base display level, for example by lowering saturation, lowering opacity, and/or de-focusing (as if the user is looking through a camera) and modification can be done variably. Driven by a relevancy score, each content item in a display layout can be de-emphasized more or less depending on which content is more meaningful to the user's filtering actions.

Abstract: A virtual image generation system and method of operating same are provided. A left synthetic image and a right synthetic image of a three-dimensional scene are rendered respectively from a first left focal center and a first right focal center relative to a first viewpoint. The first left and first right focal centers are spaced from each other a distance greater than the inter-ocular distance of an end user. The synthetic image and the right synthetic image are warped respectively to a second left focal center and a second right focal center relative to a second viewpoint different from the first viewpoint. The second left and right focal centers are spaced from each other a distance equal to the inter-ocular distance of the end user. A frame is constructed from the left and right warped synthetic images, and displayed to the end user.

Abstract: Described are improved approaches to implement color sequential displays that can mitigate problems with conventional display technologies. Color-breakup is mitigated by modifying the original color channels and adding one or more additional color channels derived from the original ones.
