Ilyes- In this case where the contents of the L & R are already rendered with the parallax inherent in the rendered images, the SetStereoDepth() function is not required. You can either set it to 0 or not call it at all (default is 0). The API is available in your scenario so that you can add additional depth to the layer contents (e.g. to make it appear in front/behind another layer that also has parallax). The API also exists so that a L/R mono layer that has a single buffer can be made to appear in front/behind the display screen.

The application can render its own L/R buffers straight to the primary surface (OpenGL content or already rendered buffers from a file, such as JPEG stereo). All that rendering is performed using a local and specific settings, such as for OpenGL the (virtual) L/R camera positions, projection and model view matrices (which doesn't necessarily reflect/match the viewer's viewing setup) and an already kind of "hard-coded" horizontal parallax for the JPEG stereo buffers. I'd like to ask what would be the usefulness of the IDirectFBDisplayLayer::SetStereoDepth() in this use-case? Would it be required so that to let the user to adjust the depth appreciation and viewing experience? -Ilyes _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
