I have a GeForce 7800GTX (driver 9742 beta) under linux and I am trying to render to texture with FSAA. I am wondering if anyone has experience with that.
FSAA does not work with CameraNode FRAME_BUFFER_OBJECT but I was hoping it could work using FRAME_BUFFER target implementation instead. Using that, if I set __GL_FSAA_MODE=4 (4x Bilinear Multisampling), I get anti-aliasing with both a standard rendering or using the CameraNode and render to quad. The renderings are identical. However if I set __GL_FSAA_MODE=7 (4x Bilinear Multisampling by 4x Supersampling), I do get some anti-aliasing but the renderings are not identical, and I am under the impression that the supersampling only works with the standard rendering... Does anyone have any idea why that may be and if it is possible to have both multisampling and supersampling with a RTT CameraNode ? thanks in advance, guillaume
