Implementations§
source§impl DirtyRegion
impl DirtyRegion
sourcepub fn new(spatial_node_index: SpatialNodeIndex) -> Self
pub fn new(spatial_node_index: SpatialNodeIndex) -> Self
Construct a new dirty region tracker.
sourcepub fn reset(&mut self, spatial_node_index: SpatialNodeIndex)
pub fn reset(&mut self, spatial_node_index: SpatialNodeIndex)
Reset the dirty regions back to empty
sourcepub fn add_dirty_region(
&mut self,
rect_in_pic_space: PictureRect,
spatial_tree: &SpatialTree
)
pub fn add_dirty_region( &mut self, rect_in_pic_space: PictureRect, spatial_tree: &SpatialTree )
Add a dirty region to the tracker. Returns the visibility mask that corresponds to this region in the tracker.
