void setPitchAngle(float pitch)
Sets pitch angle in degrees.
QDomElement writeXml(QDomDocument &doc) const
Writes configuration to a new DOM element and returns it.
void setCenterPoint(const QgsVector3D &point)
Sets center point (towards which point the camera is looking)
void readXml(const QDomElement &elem)
Reads configuration from a DOM element previously written using writeXml()
void setDistanceFromCenterPoint(float distance)
Sets distance of the camera from the center point.
void updateCamera(Qt3DRender::QCamera *camera)
Update Qt3D camera view matrix based on the pose.
Class for storage of 3D vectors similar to QVector3D, with the difference that it uses double precisi...
double y() const
Returns Y coordinate.
double z() const
