Thanks! the example was very helpful. Now I render depth buffer to the osg::Image, but there are not real depth values in the depth buffer image, Depth values are projected between [0.0, 1.0]. I projected the values of the texture, between max and min values of pixels in the whole texture, and got nice gray picture of depth buffer.
How can I get real depth values? Is there any factors, which camera use to compute depth buffer? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marcus Fritzen Sent: Friday, September 14, 2007 8:52 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Depth Buffer max and min values?
