Hello, I am Hae Chung, and studying multi-display software tools. I would like to ask some questions about the cluster rendering in OpenSG.
In OpenSG cluster, the client node runs the application, updates the scenegraphs based on the scene changes and user's inputs, and distributes the change list of the scenegraphs to server nodes. (I hope this is correct.) I have some questions: Q1. Does every server node hold the exactly same scenegraph? and Is the same change list of the scenegraph distributed to every server node? Q2. In addition to the changelist of scenegraph, does the client send some graphics primitives and texture data to the server? If not, how OpenSG perform the parallel rendering algorithms like Sort-first and sort-last? Basically these algorithms are based on sorting graphics primitives in the rendering pipeline, but I am not sure if the OpenSG still sends these data. Q3. Does Each server node render and display some part of the scenegraph ? I mean the server node renders and displays the whole scenegraph's child nodes located in a tile display? Q4. What is inside the scenegraph change list? I know that it is changes of the scenegraph for a new frame, but I would like to know what is exactly included. Transformation matrix or projection matrix? Q5. In comparison with graphics primitives, what kind of benefits can we get by sending the scenegraph chages over the network? network bandwidth? First of all, I apologize for asking these poor questions, and thank you in advance!
