Hello, I'm a new user of OpenSG. I'm working in the CAD business and like to do some dynamic modifications (highlight, moves,...) on very large models. I have read the book 'Advanced Graphics Programming Using OpenGL' written by T.McReynolds and D.Blythe.
They write on this subject: 'Fast highlighting can be generalized to allow limited manipulation of a selected depth-buffered object (a foreground object) while avoiding full scene redraws as the object is moved. The key idea is that when an object is selected the entire scene is drawn without that object, and copies of the color and depth buffer are created. Each time the foreground object is moved or modified, the color buffer and depth buffer are initialized using the saved copies. The foreground object is drawn normally, depth tested against the saved depth buffer. ...' My question is whether this algorithm can be used with the OpenSG framework? Has this already be done or is it actually a good idea? How would you solve the highlight problem today in the context of the scenegraph metapher? Some recommodation are very appreciated. kind regards Johannes Johannes Brunen DataSolid GmbH JBrunen-at-DataSolid.de www.DataSolid.com ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
