Function bevy_mod_raycast::ray_mesh_intersection

pub fn ray_mesh_intersection(
    mesh_to_world: &Mat4, 
    vertex_positions: &[[f32; 3]], 
    vertex_normals: Option<&[[f32; 3]]>, 
    pick_ray: &Ray3d, 
    indices: Option<&Vec<impl IntoUsize>>
) -> Option<Intersection>

Checks if a ray intersects a mesh, and returns the nearest intersection if one exists.
