Struct maplibre::render::tile_view_pattern::TileViewPattern

pub struct TileViewPattern<Q, B> {
    in_view: Vec<ViewTile>,
    buffer: BackingBuffer<B>,
    phantom_q: PhantomData<Q>,
}

The tile mask pattern assigns each tile a value which can be used for stencil testing.

Fields

in_view: Vec<ViewTile>

buffer: BackingBuffer<B>

phantom_q: PhantomData<Q>

Implementations

impl<Q: Queue<B>, B> TileViewPattern<Q, B>

pub fn new(buffer: BackingBufferDescriptor<B>) -> Self

pub fn update_pattern(
    &mut self,
    view_region: &ViewRegion,
    buffer_pool: &BufferPool<Queue, Buffer, ShaderVertex, IndexDataType, ShaderLayerMetadata, ShaderFeatureStyle>,
    zoom: Zoom
)

pub fn iter(&self) -> impl Iterator<Item = &ViewTile> + '_

pub fn buffer(&self) -> &B

pub fn upload_pattern(&mut self, queue: &Q, view_proj: &ViewProjection)

pub fn stencil_reference_value_2d(&self, world_coords: &WorldTileCoords) -> u8

2D version of TileViewPattern::stencil_reference_value_3d. This is kept for reference. For the 2D case we do not take into account the Z value, so only 4 cases exist.

pub fn stencil_reference_value_3d(&self, world_coords: &WorldTileCoords) -> u8

Returns unique stencil reference values for WorldTileCoords which are 3D. Tiles from arbitrary z can lie next to each other, because we mix tiles from different levels based on availability.
