Hi, I'm in the process of investigatin OpenSG to display OpenMesh meshes. I will have ~200 meshes with a total of ~2millions triangles (of course, I can use OpenMesh to decimate the meshes to lower resoltion, but I want first to try without decimating)
My application will be a CAD-like viewer but displaying a building with a very fine triangulation, splitted in different parts where each part has a different color. Some points (~500) will also be displayed on the "skin" of the building and the user will have to do a matching point-building part by picking a point (there are displayed as pyramids) and the colored building parts to associate to the point. I will need some OK performance to be able to manipulate the 3d display quite smooth (I think ~20fps should be fine). Do you think OpenSG is fast enough to handle that much information on screen ? I browsed the mailing list archives and it seems that the VBO can be used in OpenSG. Is that true ? in 1.8 or in the 2.0 trunk ? Is the trunk stable enough to be used ? Or is it better to use 1.8 ? What about antialiasing / multisampling ? Is that included ? If it's not, maybe I can use something like http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=46 to set the good pixelformat before the OpenSG init ?
