Hi Yang, first read the README file, there you can find the info, why the screen is black: ---------- Examples do load .ppu and .glsl files out of the Data directory, which can be found in the main direcotry of osgPPU. In order that this files are found you have to setup the OSG_FILE_PATH environment variable accordingly. Hence on Unix systems do following: export OSG_FILE_PATH=$OSG_FILE_PATH:/path/were/osgPPU/is/installed/ ----------
The viewer has to be activated with a .ppu parameter. for example: ./viewer Data/motionblur.ppu However you have to specify the environment variable before. cheers, art P.S. I saw there were a bug in the viewer. Please update the code from svn again, because viewer has to be run in single threaded mode (i cahnged it now). Multithreading isn't working properly now ;( --- yang zhiyuan <[EMAIL PROTECTED]> schrieb am Sa, 4.10.2008: > Von: yang zhiyuan <[EMAIL PROTECTED]> > Betreff: [osg-users] OSGPPU > An: [email protected] > Datum: Samstag, 4.
