Enum line_drawing::VoxelOrigin

pub enum VoxelOrigin {
    Corner,
    Center,
}

[−] Expand description

Whether the center or corner of a voxel is aligned with the "grid".

If the origin point of your world is at the corner of 8 voxels, use Corner. This is likely the case if you're using [gfx_voxel]. [gfx_voxel]: https://crates.io/crates/piston3d-gfx_voxel

use line_drawing::{VoxelOrigin, WalkVoxels};
 
let a = (-0.1, -0.1, -0.1);
let b = (0.1, 0.1, 0.1);
 
let center_length = WalkVoxels::<f32, i8>::new(a, b, &VoxelOrigin::Center).count();
assert_eq!(center_length, 1);
 
let corner_length = WalkVoxels::<f32, i8>::new(a, b, &VoxelOrigin::Corner).count();
assert_eq!(corner_length, 4);
