[Algorithms] 3D mesh transmittion

[Yuan-chung L. <yz...@CC...>]

Hello:

    I have a question about the 3D mesh transmission across the network.
A 3D mesh will be transmitted from a server to a client for display. If the
position of the camera is fixed for that mesh, we can first transmit the
visible polygons to shorten the latency of network transmission. 

    The method to determine those visible polygons is to pre-render the 3D mesh
and assign each polygon a different color with flat shading. Then we have the
index of visible polygons in frame buffer. This can be done off line.

    After transmitting the visible polygons, we can go on to transmit the rest
polygons to prevent from cracks in moving the camera.

    Does the method have any problem ? Have any paper discussed this before?
