Function three_d::renderer::ray_intersect

pub fn ray_intersect<S: Shadable>(
    context: &Context, 
    position: Vec3, 
    direction: Vec3, 
    max_depth: f32, 
    geometries: &[S]
) -> ThreeDResult<Option<Vec3>>

Finds the closest intersection between a ray starting at the given position in the given direction and the given geometries. Returns None if no geometry was hit before the given maximum depth.
