Member Enumeration Documentation

◆ SceneState

Enumeration of possible states of the 3D scene.

Enumerator
Ready 

The scene is fully loaded/updated.

Updating 

The scene is still being loaded/updated.

Constructor & Destructor Documentation

◆ Qgs3DMapScene()

Qgs3DMapScene::Qgs3DMapScene ( const Qgs3DMapSettings map,
QgsAbstract3DEngine engine 
)

Constructs a 3D scene based on map settings and Qt 3D renderer configuration.

Definition at line 57 of file qgs3dmapscene.cpp.

Member Function Documentation

◆ cameraController()

QgsCameraController* Qgs3DMapScene::cameraController ( )
inline

Returns camera controller.

Definition at line 66 of file qgs3dmapscene.h.

◆ registerPickHandler()

void Qgs3DMapScene::registerPickHandler ( Qgs3DMapScenePickHandler pickHandler)

Registers an object that will get results of pick events on 3D entities. Does not take ownership of the pick handler. Adds object picker components to 3D entities.

Definition at line 188 of file qgs3dmapscene.cpp.

◆ sceneState()

SceneState Qgs3DMapScene::sceneState ( ) const
inline

Returns the current state of the scene.

Definition at line 90 of file qgs3dmapscene.h.

◆ sceneStateChanged

void Qgs3DMapScene::sceneStateChanged ( )
signal

Emitted when the scene's state has changed.

◆ terrainEntity()

QgsTerrainEntity* Qgs3DMapScene::terrainEntity ( )
inline

Returns terrain entity (may be temporarily nullptr)

Definition at line 68 of file qgs3dmapscene.h.

◆ terrainEntityChanged

void Qgs3DMapScene::terrainEntityChanged ( )
signal

Emitted when the current terrain entity is replaced by a new one.

◆ terrainPendingJobsCount()

int Qgs3DMapScene::terrainPendingJobsCount ( ) const

Returns number of pending jobs of the terrain entity.

Definition at line 175 of file qgs3dmapscene.cpp.

◆ terrainPendingJobsCountChanged

void Qgs3DMapScene::terrainPendingJobsCountChanged ( )
signal

Emitted when the number of terrain's pending jobs changes.

◆ totalPendingJobsCount()

int Qgs3DMapScene::totalPendingJobsCount ( ) const

Returns number of pending jobs for all chunked entities.

Since
QGIS 3.12

Definition at line 180 of file qgs3dmapscene.cpp.

◆ totalPendingJobsCountChanged

void Qgs3DMapScene::totalPendingJobsCountChanged ( )
signal

Emitted when the total number of pending jobs changes.

Since
QGIS 3.12

◆ unregisterPickHandler()

void Qgs3DMapScene::unregisterPickHandler ( Qgs3DMapScenePickHandler pickHandler)

Unregisters previously registered pick handler. Pick handler is not deleted. Also removes object picker components from 3D entities.

Definition at line 203 of file qgs3dmapscene.cpp.

◆ viewZoomFull()

void Qgs3DMapScene::viewZoomFull ( )

Resets camera view to show the whole scene (top view)

Definition at line 168 of file qgs3dmapscene.cpp.

◆ worldSpaceError()

float Qgs3DMapScene::worldSpaceError ( float  epsilon,
float  distance 
)

Given screen error (in pixels) and distance from camera (in 3D world coordinates), this function estimates the error in world space.

Takes into account camera's field of view and the screen (3D view) size.
