What is the difference between Canvas3D and View3D in Qt Quick?
-
Hi everyone,
I'm currently working on a Qt Quick project that involves 3D rendering, and I'm trying to understand the differences between Canvas3D and View3D.
From what I've gathered so far:
Canvas3D seems to have been used in earlier versions of Qt (possibly based on WebGL-style rendering).
View3D appears to be the newer approach for integrating 3D content, especially in Qt 6, with support for scene graph and high-level QML components.
I'm a bit confused about when and why one should be used over the other. Could someone help clarify:
The core differences between the two?
Which one is recommended for current Qt versions?
Any limitations or use cases where one is preferred over the other?

Qt Canvas3D was deprecated long ago, and has been removed from Qt 6: https://bugreports.qt.io/browse/QTBUG-70510
So, you should use the Qt Quick 3D module (which contains View3D) because it's the one that is actually available and supported in Qt 6. Here is an example: https://doc.qt.io/qt-6/qtquick3d-view3d-example.html
Note: Qt Quick 3D is only available under the GPL and Commercial licenses. It is not available under LGPL.
