Abstract
Objects can be rendered in three-dimensions and viewed and manipulated in an augmented reality environment. For example, contour information for an object represented in image data for a plurality of viewpoints can be obtained. A region of space that includes the object can be partitioned into a plurality of sub regions. A position of each sub region can be identified in the image data for each viewpoint. A value can be determined for each sub region indicating whether that sub region as projected in the image data is within the contour of the object. Once the total values for each sub region are determined, a visual hull technique can be used to generate a visual hull of the object based on the values. Thereafter, the visual hull can be used to generate a three-dimensional representation of the object for a number of different viewpoints.
