Implementations

impl Occluders

fn new() -> Self

fn push(&mut self, world_rect: WorldIntRect, z_id: ZBufferId)

pub fn is_tile_occluded( &mut self, z_id: ZBufferId, world_rect: WorldRect, ) -> bool

Returns true if a tile with the specified rectangle and z_id is occluded by an opaque surface in front of it.

fn area(&mut self, z_id: ZBufferId, clip_rect: &WorldIntRect) -> i32

Return the total area covered by a set of occluders, accounting for overlapping areas between those rectangles.
