Public Member Functions | |
QgsCameraController (Qt3DCore::QNode *parent=nullptr) | |
Constructs the camera controller with optional parent node that will take ownership. More... | |
void | addTerrainPicker (Qt3DRender::QObjectPicker *picker) |
Connects to object picker attached to terrain entity. More... | |
Qt3DRender::QCamera * | camera () const |
Returns camera that is being controlled. More... | |
void | frameTriggered (float dt) |
Called internally from 3D scene when a new frame is generated. Updates camera according to keyboard/mouse input. More... | |
QgsVector3D | lookingAtPoint () const |
Returns the point in the world coordinates towards which the camera is looking. More... | |
void | readXml (const QDomElement &elem) |
Reads camera configuration from the given DOM element. More... | |
void | resetView (float distance) |
Move camera back to the initial position (looking down towards origin of world's coordinates) More... | |
void | setCamera (Qt3DRender::QCamera *camera) |
Assigns camera that should be controlled by this class. Called internally from 3D scene. More... | |
void | setLookingAtPoint (const QgsVector3D &point) |
Sets the point toward which the camera is looking - this is used when world origin changes (e.g. after terrain generator changes) More... | |
void | setViewFromTop (float worldX, float worldY, float distance, float yaw=0) |
Sets camera to look down towards given point in world coordinate, in given distance from plane with zero elevation. More... | |
void | setViewport (const QRect &viewport) |
Sets viewport rectangle. Called internally from 3D canvas. Allows conversion of mouse coordinates. More... | |
QRect | viewport () const |
Returns viewport rectangle. More... | |
QDomElement | writeXml (QDomDocument &doc) const |
Writes camera configuration to the given DOM element. More... | |
