Hi all, I have a problem with creating geometry and setting transformations form a thread in my application. What i basically try to do is: - Load a model (a large model imported from CAD-tools) -Then animate the model (set some Transformations inside of the loaded model) and create additional geometry in a second thread -Draw the model from the main application thread The problem seems to be that the changes don't get synchronized to the main thread's aspect.
My implementation generally corresponds to the 13multithreading2-example found in the OpenSG2-Sources. Also the 13multithreading2-example works when left unchanged. But when I try to change geometry in the thread this also does not seem to work. I have attached the changed sources of the 13multithreading2-example to this mail. Can somebody help me with this? I also have some questions about threads and aspects: 1. If i load a model and then call OSG::commitChangesAndClear() in the main thread after loading it, can i still make changes to the model in a thread using another aspect when i start the thread after calling OSG::commitChangesAndClear() in the main thread? Or do I have to keep the changelists in the application thread and call applicationThread->getChangeList()->applyAndClear() from the second thread so the second thread creates the necessary copies of the data in its aspect? 2. Are only the field containers which are changed by the second thread duplicated or is the whole scene duplicated? My scene has about 900MB when loaded, so duplicating the whole thing in the second aspect is not really an option...
