Constructor & Destructor Documentation

Qgs3DMapScene::Qgs3DMapScene	(	const Qgs3DMapSettings &	map,

Member Function Documentation

QgsCameraController* Qgs3DMapScene::cameraController ( )

inline

Returns camera controller.

Definition at line 61 of file qgs3dmapscene.h.

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 186 of file qgs3dmapscene.cpp.

SceneState Qgs3DMapScene::sceneState ( ) const

inline

Returns the current state of the scene.

Definition at line 79 of file qgs3dmapscene.h.

void Qgs3DMapScene::sceneStateChanged ( )

signal

Emitted when the scene's state has changed.

QgsTerrainEntity* Qgs3DMapScene::terrainEntity ( )

inline

Returns terrain entity (may be temporarily null)

Definition at line 63 of file qgs3dmapscene.h.

void Qgs3DMapScene::terrainEntityChanged ( )

signal

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

int Qgs3DMapScene::terrainPendingJobsCount

(

)

const

Returns number of pending jobs of the terrain entity.

Definition at line 181 of file qgs3dmapscene.cpp.

void Qgs3DMapScene::terrainPendingJobsCountChanged ( )

signal

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

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 202 of file qgs3dmapscene.cpp.

void Qgs3DMapScene::viewZoomFull

(

)

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

Definition at line 174 of file qgs3dmapscene.cpp.

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.
