Detailed Description

Uniquely identifies a node in a quadtree.

This is one form of a Cesium3DTilesSelection::TileID.

The identifier is composed of the level (with 0 being the level of the root tile), the x- and y-coordinate of the tile, referring to a grid coordinate system at the respective level.

Member Function Documentation

computeInvertedY()

uint32_t CesiumGeometry::QuadtreeTileID::computeInvertedY ( const QuadtreeTilingScheme & tilingScheme ) const

noexcept

Computes the inverse y-coordinate of this tile ID.

This will compute the inverse y-coordinate of this tile ID, based on the given tiling scheme, which provides the number of tiles in y-direction for the level of this tile ID.

Parameters

tilingScheme

The QuadtreeTilingScheme.

Returns

The inverted y-coordinate.

getParent()

QuadtreeTileID CesiumGeometry::QuadtreeTileID::getParent ( ) const

inlineconstexprnoexcept

Gets the ID of the parent of the tile with this ID.

If this method is called on a level zero tile, it returns itself.

Returns

The ID of the parent tile.

Definition at line 67 of file QuadtreeTileID.h.

operator!=()

bool CesiumGeometry::QuadtreeTileID::operator!= ( const QuadtreeTileID & other ) const

inlineconstexprnoexcept

Returns true if two identifiers are not equal.

Definition at line 43 of file QuadtreeTileID.h.

operator==()

bool CesiumGeometry::QuadtreeTileID::operator== ( const QuadtreeTileID & other ) const

inlineconstexprnoexcept

Returns true if two identifiers are equal.
