Detailed Description

Representation of a light source in 3D space.

Q3DLight represents a monochrome light source in 3D space.

Note: Default light has isAutoPosition() true.

Property Documentation

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)
