The correlated feature keypoints can be used to create 3D feature coordinates for the associated features of the object. A 3D skeleton can be generated using the 3D feature coordinates. One or more 3D models can be mapped to the 3D skeleton and rendered. The rendered one or more 3D models can be displayed on one or more display devices.

A method for rendering a view from a lightfield includes identifying a ray associated with a portion of the view and selecting a set of camera views from a plurality of camera views representing the lightfield based on an intersection point of the ray with a plane. Each camera view has an associated contribution region disposed on the plane. The associated contribution region overlaps contribution regions associated with other camera views of the set of camera views at the intersection point. The method also includes determining a characteristic of the ray based on a contribution factor for each camera view of the set of camera views. The contribution factor is determined based on the relative position of the intersection point within the associated contribution region.

Systems and processes are described below relating to evaluating a dependency graph to render three-dimensional (3D) graphics using constraints. Two virtual 3D objects are accessed in a virtual 3D space. A constraint relationship request is received, which identifies the first object as a parent and the second object as a child. The technique verifies whether the graphs of the objects are compatible for being constrained to one another. The first object is evaluated to determine its translation, rotation, and scale. The second object is similarly evaluated based on the translation, rotation, and scale of the first object. An image is rendered depicting at least a portion of the first virtual 3D object and at least a portion of the second virtual 3D object.

Embodiments can generate content (e.g., a feature film, virtual reality experience) in a virtual environment (e.g., a VR environment). Specifically, they allow fast prototyping and development of a virtual reality experience by allowing virtual assets to be quickly imported into a virtual environment. The virtual assets can be used to help visualize or “storyboard” an item of content during early stages of development. In doing so, the content can be rapidly iterated upon without requiring use of more substantial assets, which can be time consuming and resource intensive.

Near-to-eye displays within head mounted devices offer both users with and without visual impairments enhanced visual experiences either by improving or augmenting their visual perception. Unless the user directly views the display without intermediate optical elements then the designer must consider chromatic as well as other aberrations. Within the prior art the optical train is either complex through additional corrective elements adding to weight, cost, and size or through image processing. However, real time applications with mobile users require low latency to avoid physical side effects. Accordingly, it would be beneficial to provide near-to-eye displays mitigating these distortions and chromatic aberrations through pre-distortion based electronic processing techniques in conjunction with design optimization of the optical train with low weight, low volume, low complexity, and low cost. Further, it would be beneficial to exploit consumer grade low cost graphics processing units rather than application specific circuits.

Embodiments relate to converting spatial features to a map projection. Initially, a map request that specifies the map projection for a geographic area is obtained. A spatial feature is identified for projecting into the map projection. Until a bisect threshold is satisfied for each line segment in the spatial feature, a bisect is determined for each of the line segments; each line segment is projected into the map projection; and if the bisect threshold is not satisfied for a line segment, the line segment is divided into subsegments, where the bisect threshold specifies an error distance for the line segment after projection. The modified spatial feature is projected into the map projection to obtain a projected spatial feature, and a polar coordinate system that corresponds to the map projection is used to render the projected spatial feature in a spatial map.
