Hi guys, I am writing a wrapper for screen capturing logic. I used osgscreencapture example as a start, and it works.
However, I am experiencing strange bugs: 1. if you order the viewer to change the background color viewer.getCamera()->setClearColor(::osg::Vec4(1.0f, 0.0f, 0.0f, 1.0f); and then call viewer.frame() ther is a chance (not 100%!) that the screenshot will still have the old color. After you call viewer.frame() again, the screenshot has the new color. 2. If you first call viewer.setSceneData(NULL); and then viewer.setSceneData(pNode); where pNode is a valid pointer to OSG scene, you sometimes (again, not 100%!) still get an empty image (with no scene) if you call viewer.frame(). I suspect these bugs are related and show a more generic bug with threading. My guess would be that although .frame() call goes after the change to viewer's setting, somehow the frame() call uses old values. I built up a small example which shows when these bugs appear by me. Thank you!
