Expand description
A helper that maps a range of values to and from the normalized
range [0.0, 1.0]
using various gradients, useful for DSP applications.
(currently in beta)
§Installation
Add normal_map
as a dependency in your Cargo.toml
:
normal_map = 0.2
§Example
// Import normal mappers that use internal f32 values.
// (f64 is available as well)
use normal_map::f32::*;
// Linear mapper
let lin_map = LinearMap::new(-50.0, 50.0, Unit::Generic);
assert!((lin_map.normalize(25.0) - 0.75).abs() <= 0.0001);
assert!((lin_map.denormalize(0.25) - (-25.0)).abs() <= 0.0001);
// Efficiently map an array/slice of values.
let in_normals = [0.0f32, 1.0, 0.25, -0.25];
let mut out_values = [0.0f32; 4];
lin_map.denormalize_array(&in_normals, &mut out_values);
// Generic type for any mapper
let normal_map = NormalMap::discrete::<isize>(-5, 5);
assert!((normal_map.normalize(3 as f32) - 0.8).abs() <= 0.0001);
