Detailed Description

Q3DLight represents a monochrome light source in 3D space.

Note: Default light has isAutoPosition() true.

Property Documentation

`[since QtDataVisualization 5.9]` autoPosition : bool

This property holds whether the light position follows the camera automatically.

Note: Has no effect if shadows are enabled. Remember to disable shadows before setting light's position, or it will be overwritten by automatic positioning if isAutoPosition() is false.

This property was introduced in QtDataVisualization 5.9.

Access functions:

bool	isAutoPosition()
void	setAutoPosition(bool enabled)

Notifier signal:

void	autoPositionChanged(bool autoPosition)

Member Function Documentation

`[explicit]` Q3DLight::Q3DLight(QObject **parent* = nullptr)

Constructs a new 3D light located at origin. An optional parent parameter can be given and is then passed to QObject constructor.

`[virtual noexcept]` Q3DLight::~Q3DLight()

Destroys the light object.
