Functions

QUALITY

#

#define QUALITY(q) ((q) < 5 ? 1.0 : ((q) > 5 ? ((q) < 10 ? 2.0 : ((q) < 11 ? 4.0 : 8.0)) : 1.5))

fn QUALITY (
q: i32
) -> f32

rgb2luma

#
fn rgb2luma (
rgb: vec3<f32>
) -> f32

fragment

#
@fragment
Calculates the final color of each pixel on the screen

Performs FXAA post-process anti-aliasing as described in the Nvidia FXAA white paper and the associated shader code.

fn fragment (
in: FullscreenVertexOutput
) ->
