Questions tagged [fxaa]

FXAA is short for Fast Approximate Anti-Aliasing. This was designed by Timothy Lottes of NVIDIA. It ignores polygons and line edges, and simply analyzes the pixels on the screen. It is a pixel shader program documented in this PDF that runs every frame in a scant millisecond or two. Where it sees pixels that create an artificial edge, it smooths them.

When I'm using PHP's GD image library to draw shapes it always shows hard edges. I've tried to use GD's imageantialias() function but that is for straight lines only. In order to solve the problem, I've searched some anti-aliasing algorithms and…

When I'm creating a Widget, and draw a circle on its canvas, the circle hasn't got a smooth outline. To fix that, I thought an EffectWidget would help me, as it once did with an ImageWidget on it. But enabling FXAAEffect on it after drawing a circle…

FXAA Parameter Confusion
