#ActualSynthetix

Posted 06 February 2013 - 06:56 AM

I have a simple shader that does some image processing on 2D images (textures) and then renders them at video resolutions like 1920x1080. The problem is that the viewport in the UI through which the user views the render is smaller, say a phone size screen. So, although my render is 1920x1080, the viewport is actually much smaller. The result of this is lots of aliasing in the viewport due to the downscaling of the larger render to the smaller viewing area.

What can I do to reduce the aliasing? Is there a standard technique used in this case?
