Abstract: Due
to the problem of Web-based CAD/CAE applications sharing in real time
with which the mechanical product synchronous cooperative design is
facing two difficulties of limited capability of net transmission and
real time rendering rise in the area, thus the application results in
the domain are scarce. The novel tactic of inserting middle layers
comprising of the module of dispersing and module of image cubic-spline
interpolation between the display buffer and net buffer is proposed to
overcome the above difficulties. The module of dispersing is employed to
decrease the charge of net transmission. The module of interpolation is
employed to improve the efficiency of redrawing shared interface.
Because the consuming computing is distributed to respective client ends
to avoid the dissipative computing online, the reconstructed interfaces
with cubicspline interpolation is fast and smooth, the efficiency and
real time capability of synchronous cooperative design are improved
substantially.
