Structures

DataRanges

#

vertex_start is the starting offset of the mesh data in the vertex_data storage buffer index_start is the starting offset of the index data in the index_data storage buffer

struct DataRanges {
vertex_start: u32,
vertex_end: u32,
index_start: u32,
index_end: u32,
}

Functions

main

#
@compute
Runs custom parallel code on the GPU, not limited to graphics
@workgroup_size(1)
Defines the size of a thread group. One to three numbers: width (x), height (y), and depth (z). Missing values default to 1
fn main (
@builtin(global_invocation_id)
global_id: vec3<u32>
)
