Function bevy_mod_raycast::ray_mesh_intersection

pub fn ray_mesh_intersection(
    mesh_transform: &Mat4,
    vertex_positions: &[[f32; 3]],
    vertex_normals: Option<&[[f32; 3]]>,
    ray: &Ray3d,
    indices: Option<&Vec<impl IntoUsize>>,
    backface_culling: Backfaces
) -> Option<IntersectionData>

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