Struct Occluders

Source

pub struct Occluders {
    occluders: Vec<Occluder, FrameAllocator>,
    scratch: OccludersScratchBuffers,
}

Expand description

List of registered occluders.

Also store a couple of vectors for reuse.

Implementations§

Source §

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.

Source

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.
