Struct HeightFieldCollider 

pub struct HeightFieldCollider;

Collision detector for ray-heightfield intersection.

Implementations

impl HeightFieldCollider

pub fn ray_cast( surface: &HeightFieldSurface, origin: Vec3, direction: Vec3, max_distance: f32, step_size: f32, ) -> Option<HeightFieldHit>

Cast a ray against a height field surface using ray marching + binary search refinement.

The ray starts at origin and moves in direction (should be normalized). max_distance limits the search. step_size controls the initial march resolution.

pub fn is_above(surface: &HeightFieldSurface, point: Vec3) -> bool

Test if a point is above or below the terrain.

pub fn distance_to_surface(surface: &HeightFieldSurface, point: Vec3) -> f32

Get the vertical distance from a point to the terrain surface.

pub fn project_onto(surface: &HeightFieldSurface, point: Vec3) -> Vec3

Project a point onto the terrain (snap Y to terrain height).

pub fn sphere_intersects( surface: &HeightFieldSurface, center: Vec3, radius: f32, ) -> bool

Sphere-terrain intersection test. Returns true if a sphere at center with given radius intersects the terrain.
