Applies random wave curves to particles. 更多...
| import 语句： | import QtQuick3D.Particles3D |
| Since: | Qt 6.2 |
| 继承： | Affector3D |
This element applies random wave curves to particles. Curves can combine global values which are the same for all particles and unique values which differ randomly.
|
fadeInDuration : int |
This property defines the duration in milliseconds for fading in the affector. After this duration, the wandering will be in full effect. Setting this can be useful to emit from a specific position or shape, otherwise wander will affect position also at the beginning.
默认值为
0
.
|
fadeOutDuration : int |
This property defines the duration in milliseconds for fading out the affector. Setting this can be useful to reduce the wander when the particle life time ends, for example when combined with Attractor3D so end positions will match the shape .
默认值为
0
.
|
globalAmount : vector3d |
This property defines how long distance each particle moves at the ends of curves. So if the value is for example (100, 10, 0), all particles wander between (100, 10, 0) and (-100, -10, 0).
默认值为
(0.0, 0.0, 0.0)
.
|
globalPace : vector3d |
This property defines the pace (frequency) each particle wanders in curves per second.
默认值为
(0.0, 0.0, 0.0)
.
|
globalPaceStart : vector3d |
This property defines the starting point for the pace (frequency). The meaningful range is between 0 .. 2 * PI. For example, to animate the x-coordinate of the pace start:
PropertyAnimation on globalPaceStart {
loops: Animation.Infinite
duration: 2000
from: Qt.vector3d(0, 0, 0)
to: Qt.vector3d(Math.PI * 2, 0, 0)
}
默认值为
(0.0, 0.0, 0.0)
.
|
uniqueAmount : vector3d |
This property defines how long distance each particle moves at the ends of curves at maximum.
默认值为
(0.0, 0.0, 0.0)
.
|
uniqueAmountVariation : real |
This property defines variation for uniqueAmount between 0.0 and 1.0. When the amount variation is 0.0, every particle reaches maximum amount. When it's 0.5, every particle reaches between 0.5 - 1.5 of the amount. For example if uniqueAmount is (100, 50, 20) and uniqueAmountVariation is 0.1, the particles maximum wave distances are something random between (110, 55, 22) and (90, 45, 18).
默认值为
0.0

uniquePace : vector3d |
This property defines the unique pace (frequency) each particle wanders in curves per second.
默认值为
(0.0, 0.0, 0.0)
.
|
uniquePaceVariation : real |
This property defines the unique pace (frequency) variation for each particle between 0.0 and 1.0. When the variation is 0.0, every particle wander at the same frequency. For example if uniquePace is (1.0, 2.0, 4.0) and uniquePaceVariation is 0.5, the particles wave paces are something random between (2.0, 4.0, 8.0) and (0.5, 1.0, 2.0).
