Abstract
Enables real-time depth modifications to stereo images of a 3D virtual reality environment locally and for example without iterative workflow involving region designers or depth artists that includes re-rendering these images from the original 3D model. Embodiments generate a spherical translation map from the 3D model of the virtual environment; this spherical translation map is a function of the pixel shifts between left and right stereo images for each point of the sphere surrounding the viewer of the virtual environment. Modifications may be made directly to the spherical translation map, and applied directly to the stereo images, without requiring re-rendering of the scene from the complete 3D model. This process enables depth modifications to be viewed in real-time, greatly improving the efficiency of the 3D model creation, review, and update cycle.
