Test Quick3D app outside dev environement

  • I want to show a quick3D qml with qmlviewer in a laptop for a presentation.

    How can I do that without installing dev environnement on this laptop?

    (I copy all needed dll, however in qmlviewer I get module qt3D is not installed)

  • See my answer to the question "Qt dll deployment on windows": And you have to start qmlviewer with the option -opengl.

  • On windows, you should create a folder with the contents:
    ./Qt3D - folder from QTDIR/imports
    ./main.qml - Your presentation
    ./and other depends

    If you want to load .3ds scene, then add the folder:
    ./sceneformats - folder from QTDIR/plugins

    For example, main.qml:
    @import QtQuick 1.1
    import Qt3D 1.0
    import Qt3D.Shapes 1.0

    Viewport {
    width: 480; height: 320

    Teapot {
        effect: Effect {
            color: "gold"


    Now run Your presentation:

    qmlviewer -opengl main.qml

    Good luck!
