Detailed Description

Tile - A tile in a 3D Tiles tileset.

Member Function Documentation

addChild()

void Maria3D::Tiles3D::Tile::addChild ( const std::shared_ptr< Tile > &  tile )

inline

An array of objects that define child tiles. Each child tile content is fully enclosed by its parent tile's bounding volume and, generally, has a geometricError less than its parent tile's geometricError. For leaf tiles, the length of this array is zero, and children may not be defined.

getChildren()

const std::vector< std::shared_ptr< Tile > > & Maria3D::Tiles3D::Tile::getChildren ( ) const

inline

An array of objects that define child tiles. Each child tile content is fully enclosed by its parent tile's bounding volume and, generally, has a geometricError less than its parent tile's geometricError. For leaf tiles, the length of this array is zero, and children may not be defined.

getGeometricError()

double Maria3D::Tiles3D::Tile::getGeometricError ( ) const

inline

The error, in meters, introduced if this tile is rendered and its children are not. At runtime, the geometric error is used to compute screen space error (SSE), i.e., the error measured in pixels.

getRefine()

Refine Maria3D::Tiles3D::Tile::getRefine ( ) const

inline

Specifies if additive or replacement refinement is used when traversing the tileset for rendering. This property is required for the root tile of a tileset; it is optional for all other tiles. The default is to inherit from the parent tile.

getTransform()

const STK::Matrix4x4f & Maria3D::Tiles3D::Tile::getTransform ( ) const

inline

Tile transform. This 4x4 affine matrix transforms the tile's content content–i.e., its features as well as content.boundingVolume, boundingVolume, and viewerRequestVolume – from the tile's local coordinate system to the parent tile's coordinate system, or, in the case of a root tile, from the tile's local coordinate system to the tileset's coordinate system.

The transform does not apply to geometricError, nor does it apply any volume property when the volume is a region, defined in EPSG:4979 coordinates.

getViewerRequestVolume()

const std::shared_ptr< BoundingVolume > & Maria3D::Tiles3D::Tile::getViewerRequestVolume ( ) const

inline

A bounding volume that encloses a tile or its content. This volume can be used to trigger rendering of the tile and its children. The tile should only be active when the viewer is inside this volume.

setGeometricError()

void Maria3D::Tiles3D::Tile::setGeometricError ( double  geometricError )

inline

The error, in meters, introduced if this tile is rendered and its children are not. At runtime, the geometric error is used to compute screen space error (SSE), i.e., the error measured in pixels.

setRefine()

void Maria3D::Tiles3D::Tile::setRefine ( const Refine &  refine )

inline

Specifies if additive or replacement refinement is used when traversing the tileset for rendering. This property is required for the root tile of a tileset; it is optional for all other tiles. The default is to inherit from the parent tile.

setTransform()

void Maria3D::Tiles3D::Tile::setTransform ( const STK::Matrix4x4f &  transform )

inline

Tile transform. This 4x4 affine matrix transforms the tile's content content–i.e., its features as well as content.boundingVolume, boundingVolume, and viewerRequestVolume – from the tile's local coordinate system to the parent tile's coordinate system, or, in the case of a root tile, from the tile's local coordinate system to the tileset's coordinate system.

The transform does not apply to geometricError, nor does it apply any volume property when the volume is a region, defined in EPSG:4979 coordinates.

setViewerRequestVolume()

void Maria3D::Tiles3D::Tile::setViewerRequestVolume ( const std::shared_ptr< BoundingVolume > &  viewerRequestVolume )

inline

A bounding volume that encloses a tile or its content. This volume can be used to trigger rendering of the tile and its children. The tile should only be active when the viewer is inside this volume.
