A method includes generating a depth map of a real environment as seen from a viewpoint that comprises pixels having corresponding depth values of one or more physical objects. A first two-dimensional occlusion surface is generated representing at least a visible portion of the one or more physical objects located within a first predetermined depth range defined relative to the viewpoint. A second two-dimensional occlusion surface is generated such that a minimum depth of a second predetermined depth range is greater than a maximum depth of the first predetermined depth range. The first and second occlusion surfaces are posed in a three-dimensional coordinate system. The visibility of a virtual object is determined relative to the one or more physical objects by comparing a model of the virtual object with the first and second occlusion surfaces, and an output image is generated based on the visibility of the virtual object.

A method includes generating a depth map of a real environment as seen from a viewpoint that comprises pixels having corresponding depth values of one or more physical objects. Based on the depth map a two-dimensional occlusion surface is generated representing at least a visible portion of the one or more physical objects that are located within a predetermined depth range defined relative to the viewpoint. The two-dimensional occlusion surface is posed in a three-dimensional coordinate system such that the two-dimensional occlusion surface is located at a predetermined distance from the viewpoint.

Disclosed herein is a modular computing device that provides a user options to upgrade an existing computing device as improved expansion units become available without rendering the underlying base unit obsolete. The base unit of the modular computing device receives high-voltage AC power and one or more power supplies within the base unit converts the AC power to low-voltage DC power that is consumed within the base unit. An AC power transfer unit transfers AC power from the base unit to an expansion unit installed within an expansion dock of the base unit. One or more power supplies within the expansion unit convert the received AC power to low-voltage DC power that is consumed within the expansion unit.

Systems, methods, and software are disclosed herein for compressing audio data. In an implementation, sampled values of an audio signal have a dynamic range. A division of the dynamic range, into at least a lower range and an upper range, is identified based on a fixed mapping of a lower portion of the sampled values to a subset of quanta in a set of quanta having a depth less than a depth of the sampled values. Then an adaptive mapping of an upper portion of the sampled values to a remaining subset of quanta in the set of quanta is also identified, based at least on a dimension of the upper range. The fixed mapping is used to encode the lower portion of the sampled values based, while the adaptive mapping is used to encode the upper portion of the sampled values based on the adaptive mapping.
