Hi Robert, Thanks, I've checked that, it is a quite extensive documentation.
I also have two question about the basic types. Consider that we have a point cloud (a set of points). As far as I understood, in openGL when we add the pointcloud by a sequence of glVertex calls, openGL makes a copy of the coordinate values. Now when we have OSG we add the points by a osg::Geometry object. Q1: Is that right that we have 2 places in memory for each coordinate (one for openGL and one for OSG)? Since I have another layer of geometric processing I have to keep the points somewhere else too (I'm restricted to use my own point objects). So.. Q2: Is there any approach that I can use a custom point/vec3 (my own type) instead of osg::Vec3 in osg::Geometry? By that I mean having shared point objects for both OSG and my application. Of course I don't want to do it just for less memory occupation but to get easer access between the two data sets (e.g. when I do interactive selection I can select the points by OSG but I have to select them in the other data set too). Thanks for your suggestions, Cheers, Soheil __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
