Detailed Description

The base class for effects in a Qt 3D scene.

The QEffect class combines a set of techniques and parameters used by those techniques to produce a rendering effect for a material.

See also QMaterial, QTechnique, and QParameter.

Member Function Documentation

QEffect::QEffect(Qt3DCore::QNode *parent = nullptr)

Default constructs an instance of QEffect.

[protected] QEffect::QEffect(QEffectPrivate &dd, Qt3DCore::QNode *parent = nullptr)

Copy constructor.


Destroys the instance of QEffect.

void QEffect::addParameter(QParameter *parameter)

Adds parameter to the effect. It sends a QPropertyNodeAddedChange to the backend. The parameter will be used to set a corresponding uniform value in the shader used by this effect.

void QEffect::addTechnique(QTechnique *t)

Adds a new technique t to the effect. It sends a QPropertyNodeAddedChange to the backend.

QVector<QParameter *> QEffect::parameters() const

Returns the list of parameters used by the effect.

void QEffect::removeParameter(QParameter *parameter)

Removes a parameter parameter from the effect.

void QEffect::removeTechnique(QTechnique *t)

Removes a technique t from the effect.

QVector<QTechnique *> QEffect::techniques() const

Returns the list of techniques used by the effect.
