1. A method of stereoscopic panoramic image capture of a virtual environment implemented by one or more processing devices, comprising the steps of: pausing a state of a virtual environment being implemented by an application; and for each of a plurality of positions in the virtual environment: rendering in turn plural images collectively encompassing a panoramic view, capturing in turn each of the plural rendered images, capturing distance data describing a distance between a respective position in the virtual environment and surfaces in the virtual environment visible at that respective position, and saving the captured images and distance data as a captured stereoscopic panoramic image data set; wherein the plurality of positions in the virtual environment form vertices of a bounding space within which to form left and right viewpoints of a stereoscopic image using pixel information from the captured images.
