object nodes in the set of visible and undefined object nodes from the server to the client, the
graphical client renders the scene from the object nodes.
Claim 1 is illustrative of the claimed invention and reads as follows:
1. A computer-implemented method for synchronizing data between a graphical
client and a server, comprising:
(a) downloading one or more root object nodes of a scene from the server to the
graphical client, wherein the scene is a collection of parameter values for rendering a model;
(b) intersecting bounding volumes for the object nodes with a view frustum in the
graphical client to determine a set of visible and undefined object nodes, wherein the view
frustum is the part of the model between cutting planes defined by the scene; and
(c) downloading the object nodes in the set of visible and undefined object nodes
from the server to the graphical client, wherein the graphical client renders the scene from
the object nodes.
