qt3d | Qt3D - Qt5 is a rapidly changing bleeding edge environment | Development Tools library

I've been trying to build Qt 6.2.2 from source. I downloaded the sources package from the online installer but it fails each time, each time with a different error. I've tried a variety of configurations such as:

The following CMake's action will delete executable if RPATH is not the same.

I developed an application using Qml and Python. This application uses the Qt3D module of Qml for the 3D rendering of .stl files. This application works fine when running in python But the problem is that when I create an executable file by using Pyinstaller it shows the following error after running the created .exe file:

I created some entities using qt3d in QML. For example, this code shows a Scene3D element that declares RootEntity which is another QML element that contains the scene graph:

How can I disable ilumination and shadowing effects and just use global ilumination in all the Qt3D scene? I've only found this at the documentation: https://doc.qt.io/qt3dstudio/lights.html and it seems like there are three types of lightning: points, directional and area, but not a way of just drawing items using his default color.

Using Qt Quick 3D QML and without having additional C++, how could I multiply two quaternions?

I have a fixed rotation value given in quaternion (Qt.quaternion(a,b,c)), to which I would like to add a variable part.

Documentation is very scarce about that (I only found quaternion and Transform) and apparently there is no "times()" property similar to the one from vector. On the C++ side, I can multiply and normalize quaternions (QQuaternion)

I am trying to build Qt3D as it seems to not ship by default with Qt6 anymore.

I just finished installation on ubuntu, without major issue (it would have helped if the install instruction could have mentioned that the vulkan sdk is required, which was not obvious, but after installing the SDK the compilation finished successfully). I used the Qt Creator to build the library.

I am trying to do the same on windows, I installed both perl and vulkan as per install instructions above. After opening the qt3d.pro project and attempting to build it in Release mode, I am getting stuck where vulkan is requires

I have a program the takes keyboard input in the mainwindow and does some stuff with it, so it is already getting handled there. As context: The mainwindow has a Qt3DWindow widget next to a bunch of input displays that change when keyboard buttons are pressed.

The program works as expected and keyEvents are being processed in the mainwindow until the user goes to interact with the Qt3DWindow and move it around with their mouse(I have an OrbitCameraController there so you can look around). Once this happens, the window seems to take MouseEvents AND KeyEvents with it. So if a key is pressed after the Qt3DWindow is clicked, then mainwindow doesnt detect the event and does nothing. Everything goes back to normal if you just click outside of the Qt3DWindow widget

TLDR:

What I expect: I expect that even if the user interacts with the Qt3DWindow with the mouse and looks around, they can still use the keyboard and the input displays will still work outside the Qt3DWindow widget.

What happens: KeyEvents are no longer passed into the mainwindow and input displays do not work until mainwindow is clicked again.

What I have tried: Here is the code the for context, as this is where the final widget is made then added to a layout on the application. Figure I modify the widget here before its added so it doesn't take keyEvents.

I'm having a lot of issues to have a simple working app that load a light mesh in Qt3D, nothing shows up on screen.

Here's some code I put together to have a have striped down to show.

You'll notice that it's a shorter version of this Qt example

• You won't see it in this example but in my actual project I already tried loading it with
  • qrc and
  • localfile QUrl
• Qt3DExtras::QTorusMesh work without an issue.
• I tried to watch the loading status of the mesh, on my actual project it does go from None though Loading to Loaded
• Also, I have no trouble loading the file su.obj using a Qt QML example, so it's not the file that is corrupted. The file being a simple Suzanne from Blender, exported.
• I used Qt5 and 6.
• Finally, I know the question has been asked a few times, but nothing helped.
