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. 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. 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 two-dimensional occlusion surface, and an output image is generated based on the visibility of the virtual object.
