Re: [Interest] Picking in Quick3D custom models and mapFrom3DScene() question
Hi
As stated above, explicit setting the camera in View3D will make mapTo3DScene()
work, but it will break the View3D display content. I have created a bug report
[QTBUG-94539] mapTo3DScene() will fail when a camera is not explicit assigned -

Hi
After checking the qt source code, I found that I have to explicit set the
camera in View3D:
camera: OrthographicCamera{ id: mainCamera z: 300 }
Now it works

Hi
I'm trying to pick a custom model in quick3D, the model is QQuick3DGeometry
based with 4 vertexs with primitive TriangleStrip (basically I'm simulating a
line with width).
Picking works with regular Models (Sphere, Cube, ...) but fails with my custom
model.
IIRC picking is still not implemented in custom models ? Does anyone know
current status of picking, if it is planned for Qt 6.2 ?
For now I will implement my own picking for custom models wich leads to my
second question:
I'm getting an error trying to use View3D.mapToScene( ), my code is something
like:
View3D { id: view ... OrthographicCamera{ id:
mainCamera z: 300 } ...}
MouseArea { id: ma anchors.fill: view
onMouseXChanged: { var pos3D = view.mapTo3DScene(Qt.vector3d(mouseX,
mouseY, 0)) console.log("pos3D: "+pos3D) }}
The error:QML View3D: Cannot resolve scene position without a camera assigned!
Am I misunderstanding how to use mapTo3DScene, is this a bug, or what am I
missing ?
Thank youJoão
