Hi, I just did some tests on OpenSG and OpenSceneGraph to find out which better suits my needs (Performance) So I wrote some little testing programs, loaded a VRML or an OBJ file (OpenSceneGraph doesn't seem to support VRML) and measured the framerates.
You can find the results here: http://www.uni-koblenz.de/~schmecko/Seite.htm As a basic file I used the tie.wrl that comes with OpenSG. To create larger scenes I simply multiplied the number of the tie-fighters in the scene (up to 729= 9*9*9). Since OpenSceneGraph doesn't seem to support VRML I converted the files into the .obj-format. I tested both (wrl and obj) with OpenSG. Some things were pretty strange. First of all OpenSceneGraph was sometimes twice as fast as OpenSG (tie243.wrl), which I did not expect. I tried to match the setups as closely as possible given the short time I had. But even if there was a slight advantage for OpenSceneGraph, the results seem odd to me. Secondly, OpenSG 1.8 seems to be slower than OpenSG 1.6. But this I cannot really say, because with OpenSG 1.6 I only built my code myself, and used the precompiled binaries from the web. With OpenSG 1.8 I compiled everything myself, inlcuding the OpenSG libraries, with the VS 8.0 compiler. I would be glad to get some comments on the tests. Maybe some improvements on the procedure? If you want I will gladly upload some sceenshots and more info about the testing procedure.
