Struct CollisionHull

Source

pub struct CollisionHull {
    pub heights: Vec<f32>,
    pub resolution: usize,
    pub chunk_size: f32,
    pub height_scale: f32,
}

Expand description

A simplified collision representation for a terrain chunk.

Uses a low-resolution height grid suitable for physics queries.

Fields§

§heights: Vec<f32>

Low-res height grid (collision_res x collision_res cells).

§resolution: usize§chunk_size: f32

World width/height covered by this hull.

§height_scale: f32

Implementations§

Source §

impl CollisionHull

Source

pub fn generate( heightmap: &HeightMap, chunk_size: f32, height_scale: f32, resolution: usize, ) -> Self

Generate a collision hull from a heightmap.

resolution controls how many cells wide the collision grid is. Typically 8–32 for performance.

Source

pub fn height_at_local(&self, lx: f32, lz: f32) -> f32

Sample height at world-space (x, z) relative to chunk origin.

Source

pub fn triangles(&self) -> Vec<[[f32; 3]; 3]>

Returns a set of triangles for this hull (for physics engine submission).
