Yep, perlin noise always returns 0 on integer values. If you're feeding it coordinates from an integer grid people usually apply some scale factor (division) to their coordinates to make them not all be whole numbers.
Hi, I'm new to rust and experimenting with perlin noise. With a little test program based on the example I get strange results from perlin noise:
`use noise::{NoiseFn, Perlin, Seedable};
fn main() { let perlin = Perlin::new(1); println!("{}", perlin.get([42.4, 37.7])); // => -0.23845001564978627 println!("{}", perlin.get([0.0, 0.0])); // => 0 println!("{}", perlin.get([1.0, 1.0])); // => 0 println!("{}", perlin.get([10.0, 10.0])); // => 0 println!("{}", perlin.get([0.00001, 0.0])); // => 0.000014142135637872595 }`
Is that the intended behaviour? Am I doing something wrong?
