Detailed Description
The ModelParticle3D is a logical particle element that creates particles from a Qt Quick 3D Model component.
Property Documentation
delegate : Component |
The delegate provides a template defining each object instantiated by the particle.
For example, to allocate 200 red cube particles:
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" }
instanceTable : Instancing |
The instanceTable provides access to the Instancing table of the model particle. ModelParticle3D uses an internal instance table to implement efficient rendering. This table can be applied to the 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 delegate property. For example:
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" } }
