Struct TerrainLayer

pub struct TerrainLayer {
    pub name: String,
    pub noise: SeededNoise,
    pub options: NoiseOptions,
    pub height_bias_spline: SplineMap,
    pub height_offset_spline: SplineMap,
}

A layer to the terrain. Consists of two spline graphs: height bias and height offset graphs. Height bias is how much terrain should be compressed as y-coordinate increases, and height offset is by how much should the entire terrain shift up and down.

Fields

name: String

noise: SeededNoise

options: NoiseOptions

height_bias_spline: SplineMap

height_offset_spline: SplineMap

Implementations

impl TerrainLayer

pub fn new(name: &str, options: &NoiseOptions) -> Self

Create a new terrain layer from a specific noise configuration. The noise options are used for this layer to be mapped to the height bias and height offset spline graphs.

pub fn add_bias_point(self, point: [f64; 2]) -> Self

Add a point to the bias spline graph.

pub fn add_bias_points(self, points: &[[f64; 2]]) -> Self

Add a set of points to the bias spline graph.

pub fn add_offset_point(self, point: [f64; 2]) -> Self

Add a point to the height offset spline graph.

pub fn add_offset_points(self, points: &[[f64; 2]]) -> Self

Add a set of points to the height offset spline graph.

pub fn sample_bias(&self, x: f64) -> f64

Sample the bias at a certain x-value.

pub fn sample_offset(&self, x: f64) -> f64

Sample the offset at a certain x-value.

pub fn set_seed(&mut self, seed: u32)

Set the seed of the noise generator.

pub fn normalize(&mut self)

Normalize the spline graphs.
