Struct Terrain 

pub struct Terrain<M: Material> { /* private fields */ }

A terrain geometry based on a height map and with an applied material.

Implementations

impl<M: Material + Clone> Terrain<M>

pub fn new( context: &Context, material: M, height_map: Arc<dyn Fn(f32, f32) -> f32 + Send + Sync>, side_length: f32, vertex_distance: f32, center: Vec2, ) -> Self

Creates a new Terrain. The height map is a function of the (x, z) coordinates which returns the height of the terrain y.

pub fn height_at(&self, position: Vec2) -> f32

Returns the height at the given position.

pub fn set_lod(&mut self, lod: Arc<dyn Fn(f32) -> Lod + Send + Sync>)

Set the function that specifies when a certain level of detail Lod is uses. The input to the function is the distance from the current camera to the center of a part of the terrain.

pub fn set_center(&mut self, center: Vec2)

Set the center of the terrain. To be able to move the terrain with the camera, thereby simulating infinite terrain.

Trait Implementations

impl<'a, M: Material> IntoIterator for &'a Terrain<M>

type Item = &'a dyn Object

The type of the elements being iterated over.

type IntoIter = IntoIter<&'a dyn Object>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
