Constructor & Destructor Documentation

QuadtreeRectangleAvailability()

CesiumGeometry::QuadtreeRectangleAvailability::QuadtreeRectangleAvailability ( const QuadtreeTilingScheme &  tilingScheme, uint32_t  maximumLevel  )

noexcept

Creates a new instance.

Parameters

tilingScheme	The QuadtreeTilingScheme.
maximumLevel	The maximum level (height of the tree) for which the availability should be tracked.

Member Function Documentation

addAvailableTileRange()

void CesiumGeometry::QuadtreeRectangleAvailability::addAvailableTileRange ( const QuadtreeTileRectangularRange &  range )

noexcept

Adds the specified range to the set of available tiles.

Parameters

range

The QuadtreeTileRectangularRange that describes the range of available tiles.

computeMaximumLevelAtPosition()

uint32_t CesiumGeometry::QuadtreeRectangleAvailability::computeMaximumLevelAtPosition ( const glm::dvec2 &  position ) const

noexcept

Computes the maximum level for the given 2D position.

This will compute the maximum level of any available tile for the given position. The position refers to the 2D space that is covered by the nodes of the quadtree.

Parameters

position

The 2D position.

Returns

The maximum level at the given position. This may be 0 if the position is not covered by the quadtree at all.

isTileAvailable()

uint8_t CesiumGeometry::QuadtreeRectangleAvailability::isTileAvailable ( const QuadtreeTileID &  id ) const

noexcept

Returns whether a certain tile is available.

This checks the availability of the tile that is described by the given QuadtreeTileID, which consists of the level and the x- and y- coordinates of the queried tile.

Parameters

id	The quadtree tile ID.

Returns

The CesiumGeometry::TileAvailabilityFlags for this tile, encoded into an uint8_t.
