Abstract: In some implementations, a computing device can simulate a virtual parallax to create three dimensional effects. For example, the computing device can obtain an image captured at a particular location. The captured two-dimensional image can be applied as texture to a three-dimensional model of the capture location.

Thus, a virtual parallax can be introduced into the generated imagery for the capture location. When presented to the user on a display of the computing device, the generated imagery may have a three-dimensional look and feel even though generated from a single two-dimensional image.

Abstract: A mixed reality (MR) simulation system includes a console and a head mounted device (HMD). The MR system captures stereoscopic images from a real-world environment using outward-facing stereoscopic cameras mounted to the HMD. The MR system preprocesses the stereoscopic images to maximize contrast and then extracts a set of features from those images, including edges or corners, among others. For each feature, the MR system generates one or more two-dimensional (2D) polylines. Then, the MR system triangulates between 2D polylines found in right side images and corresponding 2D polylines found in left side images to generate a set of 3D polylines. The MR system interpolates between 3D vertices included in the 3D polylines or extrapolates additional 3D vertices, thereby generating a geometric reconstruction of the real-world environment. The MR system may map textures derived from the real-world environment onto the geometric representation faster than the geometric reconstruction is updated.
