Your code looks ok and more or less the same to mine.
How do You check the result? If You set the field readBuffer to true only the color textures are copied back to the image. But used in a shader which reads the values You should be able to access the depth values (that are of range 0-1 I suppose) I also had the problem, that debugging the depth values visually is hard, because there may be not much difference in color between different depths if they are far away from the camera. A bit of scaling may help then. -- ------------------------------------------------------- Volker Settgast Computer Graphics tel: +43 316 873-5406 TU Graz fax: +43 316 873-5402 Inffeldgasse 16c eMail: [EMAIL PROTECTED] A-8010 Graz ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Opensg-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/opensg-users
