Constructor & Destructor Documentation

◆ QQuick3DParticle() [1/2]

QT_BEGIN_NAMESPACE QQuick3DParticle::QQuick3DParticle ( QQuick3DObject * parent = nullptr)

\qmltype Particle3D \inherits Object3D \inqmlmodule QtQuick3D.Particles3D

Abstract logical particle.

Since
6.2

This element defines the common properties of the logical particles. Particle3D is an abstract base class of particles, use \l ModelParticle3D or \l SpriteParticle3D instead.

Note
Unlike the materials used with the models, particles default to being rendered with assuming semi-transparency, and so with blending enabled. This is the desired behavior most of the time due to particle textures, color (alpha) variations, fadings etc. If you don't need the blending, set the \l hasTransparency to false for possible performance gains.

Member Function Documentation

◆ alignMode()

QQuick3DParticle::AlignMode QQuick3DParticle::alignMode ( ) const

\qmlproperty enumeration Particle3D::AlignMode

Defines the type of the alignment.

\value Particle3D.AlignNone No alignment. Particles rotation can be defined with \l {ParticleEmitter3D::particleRotation}{particleRotation}. \value Particle3D.AlignTowardsTarget Align the particles towards \l alignTargetPosition direction. \value Particle3D.AlignTowardsStartVelocity Align the particles towards their starting \l {ParticleEmitter3D::velocity}{velocity} direction.

\qmlproperty AlignMode Particle3D::alignMode

This property defines the align mode used for the particles. Particle alignment means the direction that particles face.

Note
When the \l SpriteParticle3D \l {SpriteParticle3D::billboard}{billboard} property is set to true, alignMode does not have an effect.

The default value is Particle3D.AlignNone.

◆ colorVariation()

QVector4D QQuick3DParticle::colorVariation ( ) const

\qmlproperty vector4d Particle3D::colorVariation

This property defines the color variation that is used for colorizing the particles. The values are in RGBA order and each value should be between 0.0 (no variation) and 1.0 (full variation).

For example, to create particles which will have translucent red colors between #ff0000 and #e50000, with 40% to 60% opacity:

\qml ModelParticle3D { ... color: "#7fff0000" colorVariation: Qt.vector4d(0.1, 0.0, 0.0, 0.2) } \endqml

The default value is (0, 0, 0, 0) (no variation).

◆ fadeInDuration()

int QQuick3DParticle::fadeInDuration ( ) const

\qmlproperty int Particle3D::fadeInDuration

This property defines the duration in milliseconds for the fading in effect.

Note
The fading durations are part of the particles \l {ParticleEmitter3D::lifeSpan}{lifeSpan}. So e.g. if lifeSpan is 3000, fadeInDuration is 500 and fadeOutDuration is 500, the fully visible time of the particle is 2000ms.

The default value is 250.

bool QQuick3DParticle::hasTransparency ( ) const

\qmlproperty bool Particle3D::hasTransparency

This property defines if the particle has any transparency and should be blended with the background. Usually this should be true, like when the particle color doesn't have full alpha, texture contains semi-transparent pixels or particles opacity is faded in or out. Setting this to false can be an optimization in specific cases.

int QQuick3DParticle::maxAmount ( ) const

\qmlproperty int Particle3D::maxAmount

This property defines the maximum amount of particles that can exist at the same time. You can use \l {ParticleSystem3DLogging::particlesUsed}{particlesUsed} for debugging how efficiently the allocated particles are used. If the maxAmount is too small, particles are reused before they reach the end of their \l {ParticleEmitter3D::lifeSpan}{lifeSpan}. If the maxAmount is too big, unnecessary memory is allocated for the particles.

Note
Changing the maxAmount resets all the particles in the particle system.

The default value is 100.

◆ sortMode()

QQuick3DParticle::SortMode QQuick3DParticle::sortMode ( ) const

\qmlproperty enumeration Particle3D::SortMode

Defines the sorting mode of the particle. The sorting mode determines the order in which the particles are drawn.

\value Particle3D.SortNone No sorting. \value Particle3D.SortNewest Sort based on particle lifetime, newest first. \value Particle3D.SortOldest Sort based on particle lifetime, oldest first. \value Particle3D.SortDistance Sort based on distance to the camera, farthest first.

\qmlproperty SortMode Particle3D::sortMode

This property defines the sort mode used for the particles.

The default value is Particle3D.SortNone.

◆ unifiedColorVariation()

bool QQuick3DParticle::unifiedColorVariation ( ) const

\qmlproperty bool Particle3D::unifiedColorVariation

This property defines if the \l colorVariation should be applied uniformly for all the color channels. This means that all variations are applied with the same random amount.

For example, to create particles which will have yellow colors between #ffff00 and #7f7f00, so that the values of R and G color channels are always the same:

\qml ModelParticle3D { ... color: "#ffff00" colorVariation: Qt.vector4d(0.5, 0.5, 0.0, 0.0) unifiedColorVariation: true } \endqml

The default value is false.
