pub struct TerrainRaycastSystem;

System for batched terrain raycasts.

Implementations

impl TerrainRaycastSystem

pub fn batch_raycast( hm: &HeightMap, chunk_size: f32, height_scale: f32, rays: &[(Vec3, Vec3)], max_dist: f32, ) -> Vec<Option<(f32, Vec3)>>

Cast multiple rays against a heightmap. Returns vec of (hit_dist, hit_pos) or None per ray.

pub fn first_hit( hm: &HeightMap, chunk_size: f32, height_scale: f32, rays: &[(Vec3, Vec3)], max_dist: f32, ) -> Option<(usize, f32, Vec3)>

Find the first ray that hits terrain. Returns index and hit info.
