In one implementation, a method involves tessellating a surface of a 3D object by identifying vertices having 3D positions. The method transforms the 3D positions into positions for a first sphere-based projection for a left eye viewpoint and positions for a second sphere-based projection for a right eye viewpoint. Transforming the 3D positions of the vertices involves transforming the vertices based on a user orientation (i.e., camera position) and differences left and right eye viewpoints (e.g., based on interaxial distance and convergence angle). The method further renders a stereoscopic 360 rendering of the 3D object based on the first sphere-based projection for the left eye viewpoint and the second sphere-based projection for the right eye viewpoint. For example, an equirectangular representation of the first sphere-based projection can be combined with an equirectangular representation of the second sphere-based projection to provide a file defining a stereoscopic 360 image.

Example implementations described herein are directed to systems and methods for providing a panoramic video connection between one location and another, or between one location and a number of distributed remote viewers, which provides reciprocity in terms of awareness of who is viewing and what they are looking at. In example implementations described herein, radial displays present panoramic video from remote locations, or synthesized views of face shots positioned to indicate the viewing direction of remote viewers.

A projection system includes a visible light projector, a camera and an image processor. The visible light projector projects an image with visible light onto the object. The camera captures an image of the object and has an optical axis not coinciding with an optical axis of the visible light projector.

The corrector corrects a deviation between a projection image and the object. The corrector is configured to calculate a projection region on the object onto which an image is projected by the visible light projector. The image generator is configured to generate image data to project the image to be projected onto the object onto the projection region.
