Antialiasing with Transparency This sample demonstrates the GeForce 7 Series per-primitive super-sample and multi-sample modes for antialiasing primitives with transparent fragments. The problem with using alphatest to virtually simulate geometry is a hard edge that is produced where the test occurs. The conventional solution for dealing with this problem is to use alpha blending. Using a GeForce 7 Series GPU, you can enable super-sampling or multi-sampling per-primitive, yielding much higher image quality along the alpha tested edges. |
