HIGH QUALITY EMBEDDED GRAPHICS FOR REMOTE VISUALIZATION

摘要

Apparatuses and methods for rendering and compositing two-dimensional images for remote visualization using a multi-pass rendering technique are provided. A server computer renders a three-dimensional volume separately from one or more three-dimensional graphical objects to be embedded in the rendered image of the volume. The server compresses and transmits the separately rendered images to a client computer. The client computer decompresses the rendered images and generates a composite image using the rendered images. If a user manipulates, adds or deletes an embedded object, the client computer generates a new composite image using the previously rendered volume image. In the case of a new or manipulated embedded graphical object, the server only renders the manipulated or new object.

主权项

1. A method for rendering embedded graphics for remote visualization, the method comprising:
rendering, by a server, a two-dimensional volume rendered image from three-dimensional data captured for a volume; rendering, by the server, a two-dimensional graphic rendered image to be embedded in the two-dimensional volume rendered image from three-dimensional data for a graphic; compressing, by the server, the volume rendered image and the graphic rendered image; and transmitting, to a workstation over a network, the compressed volume rendered image and the compressed graphic rendered image.
