Advanced search tips: use spaces to require multiple terms (AND), | for alternatives (OR), wrap phrases in quotes (="a b"), =term for exact match, 'term to include, !term to exclude, ^term to match prefix, !^term to exclude prefix, .ext$ to match suffix, and !.ext$ to exclude suffix.

Structures

KeyValuePair

#

Key-value pair for sorting, with optional second sort key.

struct KeyValuePair {
key: u32 ,
key2: u32 ,
value: u32 ,
}

SortBuffer

#
struct SortBuffer {
count: atomic<i32> ,
pairs: array<KeyValuePair> ,
}

RawParticleBuffer

#

Particle buffer as an array of u32. This prevents having to specialize this shader for every single particle layout.

struct RawParticleBuffer {
data: array<u32> ,
}

Functions

main

#
@compute
Runs custom parallel code on the GPU, not limited to graphics
@workgroup_size(64)
Defines the size of a thread group. One to three numbers: width (x), height (y), and depth (z). Missing values default to 1

Fill the sorting key-value pair buffer with data to prepare for actual sorting.

fn main (
@builtin(global_invocation_id)
global_invocation_id: vec3<u32>
)
