Abstract:
A computer imaging system comprising:a central processing unit (CPU), at least one memory, and a network interface to one or more networks; at least one scene model stored in said at least one memory, each said at least one scene model having at least one first part and at least one second part, each said at least one first part having a first three-dimensional geometric model and each said at least one second part having a second three-dimensional geometric model; means for converting the first and second three-dimensional geometric models into a first and second two-dimensional image with depth information; means for comparing the pixels in the first and second two-dimensional images with depth information to determine if the second three-dimensional geometric model is in front of the first three-dimensional geometric model; means for creating a new partially transparent two-dimensional image with transparent pixels corresponding to where the second three-dimensional geometric model is in front of the first three-dimensional geometric model; means for providing the position of the partially transparent two-dimensional image with respect to the second three-dimensional geometric model; and means for transmitting the second three-dimensional model, the partially transparent two-dimensional image, and the position of the partially transparent two-dimensional image with respect to the second three-dimensional geometric model through the network interfaces to the network.
