Functions

fragment

#
@fragment
Calculates the final color of each pixel on the screen
fn fragment (
in: FullscreenVertexOutput
) ->
@location(0)
vec4<f32>

reset_indices

#

Resets all indices to 0. This means we don’t have to clear the entire layers buffer

fn reset_indices (
screen_index: i32
)

sort

#
fn sort (
screen_index: i32
, 
buffer_size: i32
, 
opaque_depth: f32
) -> SortResult

blend

#

OVER operator using premultiplied alpha see: https://en.wikipedia.org/wiki/Alpha_compositing

fn blend (
color_a: vec4<f32>
, 
color_b: vec4<f32>
) -> vec4<f32>
