Constructor & Destructor Documentation

◆ QQuick3DParticleModelParticle()

QT_BEGIN_NAMESPACE QQuick3DParticleModelParticle::QQuick3DParticleModelParticle ( QQuick3DNode * parent = nullptr )

\qmltype ModelParticle3D \inherits Particle3D \inqmlmodule QtQuick3D.Particles3D

Particle using a Qt Quick 3D Model.

Since: 6.2

The ModelParticle3D is a logical particle element that creates particles from a Qt Quick 3D \l Model component.

Member Function Documentation

◆ componentComplete()

void QQuick3DParticleModelParticle::componentComplete ( )

overrideprotectedvirtual

Invoked after the root component that caused this instantiation has completed construction.

At this point all static values and binding values have been assigned to the class.

Reimplemented from QQuick3DParticle.

Definition at line 278 of file qquick3dparticlemodelparticle.cpp.

References QQuick3DParticle::componentComplete(), QQuick3DParticle::setSystem(), and QQuick3DParticle::system().

Here is the call graph for this function:

◆ delegate()

QQmlComponent * QQuick3DParticleModelParticle::delegate ( ) const

\qmlproperty Component ModelParticle3D::delegate

The delegate provides a template defining each object instantiated by the particle.

For example, to allocate 200 red cube particles:

\qml Component { id: particleComponent Model { source: "#Cube" scale: Qt.vector3d(0.2, 0.2, 0.2) materials: DefaultMaterial { } } }

ModelParticle3D { id: particleRed delegate: particleComponent maxAmount: 200 color: "#ff0000" } \endqml

Here is the caller graph for this function:

◆ instanceTable()

QQuick3DInstancing * QQuick3DParticleModelParticle::instanceTable ( ) const

\qmlproperty Instancing ModelParticle3D::instanceTable

The instanceTable provides access to the \l Instancing table of the model particle. ModelParticle3D uses an internal instance table to implement efficient rendering. This table can be applied to the \l{Model::instancing}{instancing} property of models that are not part of the particle system.

It is also possible to use this feature to provide an instancing table without showing any particles. This is done by omitting the \l delegate property. For example:

\qml ParticleSystem3D { id: psystem ModelParticle3D { id: particleRed maxAmount: 200 color: "#ff0000" colorVariation: Qt.vector4d(0.5,0.5,0.5,0.5) }

ParticleEmitter3D { particle: particleRed velocity: VectorDirection3D { direction: Qt.vector3d(-20, 200, 0) directionVariation: Qt.vector3d(20, 20, 20) } particleScale: 0.2 emitRate: 20 lifeSpan: 2000 } }

Model { source: "#Sphere" instancing: particleRed.instanceTable materials: PrincipledMaterial { baseColor: "yellow" } } \endqml
