InstanceList QML Type▲

Inherits:: Instancing
Detailed Description▲
The InstanceList type makes it possible to define an instance table manually in QML.
The following example creates an instance table with two items:
InstanceList {
id
:
manualInstancing
instances
:
[
InstanceListEntry {
position
:
Qt.vector3d(0
, 0
, -
60
)
eulerRotation
:
Qt.vector3d(-
10
, 0
, 30
)
color
:
"red"
}
,
InstanceListEntry {
position
:
Qt.vector3d(50
, 10
, 100
)
eulerRotation
:
Qt.vector3d(0
, 180
, 0
)
color
:
"green"
}
]
}
Each InstanceListEntry is an object that can have property bindings and animations. This gives great flexibility, but also causes memory overhead. Therefore, it is not recommended to use InstanceList for procedurally generated tables containing thousands (or millions) of instances. Also, any property change to an entry will cause the entire instance table to be recalculated and uploaded to the GPU.
