    Abstract: Techniques are disclosed for a three-dimensional (3D) graphical rendering system, comprising: obtaining a first 3D graphical object, wherein the first 3D graphical object is associated with at least a first semi-transparent material, wherein the first material is associated with an adjustable density value and comprises at least a first plane (or 3D volume) with an adjustable position within a virtual environment; determining a transparency value based, at least in part, on the adjustable density value and a distance between the first plane and the first 3D graphical object (or a density of the 3D volume); and rendering, from a first viewpoint and using a first shader, at least a portion of the first 3D graphical object by applying the determined transparency value to the first material. Rendering the first 3D graphical object may further comprise blending between the first material and a second material according to the determined transparency value.

    Abstract: In one aspect, an example method includes (i) obtaining video that depicts an area across multiple frames of the video, wherein the area is part of a scene of the video, and wherein the area is suitable for having an object inserted therein; (ii) detecting the area within the obtained video and determining area characteristic data associated with the detected area; (iii) determining scene attribute data associated with the scene; (iv) using at least the determined area characteristic data and the determined scene attribute data as a basis to select an object from among a set of multiple candidate objects; (v) inserting into the detected area the selected object to generate video that is a modified version of the obtained video; and (vi) outputting for presentation the generated video.

    Abstract: The present technology pertains to systems and methods for creating and mapping three-dimensional spaces to provide an interactive experience with physical spaces and objects. Preferred embodiments of the method include generating a geometric layout by scanning a physical space; overlaying the geometric layout onto a virtual three-dimensional map of the physical space, the three-dimensional map supported by a content management system; defining an anchor in the three-dimensional map; associating a content with the anchor; receiving, from a device in within the physical space, the device's physical location and orientation; determining, by the content management system, a device location within the three-dimensional map; and outputting to the device, when the device is near and orientated with the anchor, the content associated with the anchor or an indication of the content associated with the anchor.
