Detailed Description

A description of the selection state of a Tile during the Tileset::updateViewGroup process.

Instances of this class are stored in a TilesetViewGroup for each visited Tile, and are used to track the state of the tile during the process of selecting tiles for rendering. The Tileset updates this state while traversing the tile hierarchy, tracking whether a tile was rendered, culled, or refined in the last frame.

Member Enumeration Documentation

Result

enum class Cesium3DTilesSelection::TileSelectionState::Result

strong

Enumeration of possible results of a TileSelectionState.

Enumerator
None	There was no selection result. This may be the case when the tile wasn't visited last frame.
Culled	This tile was deemed not visible and culled.
Rendered	The tile was selected for rendering.
Refined	This tile did not meet the required screen-space error and was refined.
RenderedAndKicked	This tile was rendered but then removed from the render list. This tile was originally rendered, but it got kicked out of the render list in favor of an ancestor because some tiles in its subtree were not yet renderable.
RefinedAndKicked	This tile was refined but then removed from the render list. This tile was originally refined, but its rendered descendants got kicked out of the render list in favor of an ancestor because some tiles in its subtree were not yet renderable.

Constructor & Destructor Documentation

TileSelectionState() [1/2]

Cesium3DTilesSelection::TileSelectionState::TileSelectionState ( )

inlineconstexprnoexcept

Initializes a new instance with TileSelectionState::Result::None.

Definition at line 71 of file TileSelectionState.h.

TileSelectionState() [2/2]

Cesium3DTilesSelection::TileSelectionState::TileSelectionState ( Result result )

inlineconstexprnoexcept

Initializes a new instance with a given TileSelectionState::Result.

Parameters

result

The result of the selection.

Definition at line 79 of file TileSelectionState.h.

Member Function Documentation

getOriginalResult()

Result Cesium3DTilesSelection::TileSelectionState::getOriginalResult ( ) const

inlineconstexprnoexcept

Gets the original selection result prior to being kicked.

If the tile wasn't kicked, the original value is returned.

Returns

The TileSelectionState::Result prior to being kicked.

Definition at line 111 of file TileSelectionState.h.

getResult()

Result Cesium3DTilesSelection::TileSelectionState::getResult ( ) const

inlineconstexprnoexcept

Gets the result of selection.

Returns

The TileSelectionState::Result

Definition at line 86 of file TileSelectionState.h.

kick()

void Cesium3DTilesSelection::TileSelectionState::kick ( )

inlineconstexprnoexcept

Marks this tile as "kicked".

Definition at line 127 of file TileSelectionState.h.

wasKicked()

bool Cesium3DTilesSelection::TileSelectionState::wasKicked ( ) const

inlineconstexprnoexcept

Determines if this tile or its descendents were kicked from the render list.

In other words, if its last selection result was TileSelectionState::Result::RenderedAndKicked or TileSelectionState::Result::RefinedAndKicked.

Returns

true if the tile was kicked, and false otherwise
