Abstract
Geometry and view data relating to a image sequences is transmitted from a server to a client computer. Such enables reconstruction of images by a client with reduced bandwidth for the image stream transmission. A previous-image mesh of coordinates and depth values for selected pixels from the array of pixels in a previous-image is generated at the server. The depth values are transmitted to the client. A change-in-view matrix is generated at the server and transmitted to the client. Such represents the change in viewing parameters between the previous-image and a current-image. The change-in-view matrix is applied to the previous-image mesh to create a current-image mesh, independently at both the server and at the client. Such is applied to the previous-image to generate a predicted current-image. The current-image is generated at the server and a difference between the current-image and the predicted current-image is computed. The computed difference is transmitted to the client and applied to the predicted current-image generated at the client to generate the current-image.
