Abstract
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.
