Scene3d | standalone scene3d graph for libgdx .. use | Game Engine library

I want to rotate the object in the window screen. I am using Qt/QML/Qt3D.

I write some code here to add a button in the object window display screen. With the help of this button I could rotate the object in the display screen about (90 and 180) degrees.

QML source code:

I have a 3D globe that when you click on a country, returns an overlay of users.

I've previously had everything working just a file of randomised, mock user data in a local file. However I've now received the actual database (a AWS one) and I can't seem to get the fetch to return what I need. It should accept a signal from country click then return a list of users from this and show them in the pop up.

I've taken out the actual database for now (confidential) but this is working correctly on postman and a simplified fetch request I created. It doesn't seem to work within the wider context of this app.

At this stage, it doesn't break but it just returns an empty array in the console.

console.log output for this.state... this is the state {overlay: true, users: Array(0), country: "Nigeria"}

I am attempting to render a QML component on the face of a cuboid or plane in a Scene3D scene. I have followed the example in documentation with success, but I am trying to convert this over to the C++ API as there's more I need to do with it and only C++ will suffice. This is the ctor for my class, which sets up the Entity and its components, based off the example code. I am only including the ctor for brevity. There isn't anything else in the class that should effect this.

I've created a script in python that is using PyQt5. Now everything works when I'm launching the file from my editor - Studio Code in this case.

I'm having a problem when I try to deploy an exe using PyInstaller or py2exe it gives me error on missing dll's when it's building. It still finishes building anyway, but when I try to run the exe file the cmd window just flashes for a brief moment and nothing more happens.

I suppose this is due to missing dll's and if not than I have to sort this out first anyway.

I've tried searching for the dll's I'm missing on my computer and some I couldn't find at all e.g. Qt53DInput and one I could find in what I suppose is application made in Qt - Qt5Multimedia .

I'm currently using python 3.7.4 which I've already tried reinstalling. I think I didn't try to reinstall PyQt5, should I try doing that?

I am loading a QML 3D scene from PyQT5 within an ApplicationWindow. however, I am not able to pan and rotate my custom model with the mouse.

I have a react website up and running on the web host, I am trying to add react router to it, so I installed react-router-dom using npm, but I get this error without further explanation about the error message or anything.

I tried changing react-router-dom to react-router which is the old version but I got different errors so I returned to react-router-dom.

I draw some 2d text entities in a Qt3D QML scene but some of the texts always render opaque, i.e hide the contents behind them. When looking at the scene from behind ( changing the position of the camera to Qt.vector3d(0,0,-40) ) all texts render OK.

The following image shows the wrong behaviour, I would expect the text "AAARGH" not to be rendered on a white background, but the green text shining through.

Platform is Windows 64-bit, Qt5.13.0, and Visual Studio 2019.

See the following small example that demonstrates the issue:

BrokenEntity.qml

I am trying to create a customizable Qt3D component by merging three ConeMeshes into a single entity. The user must be able to interact with the custom entity, so I have added an ObjectPicker to the file. Normally, I would use a predefined scaled .obj file, but my manager wants the objects to be drawn directly by Qt.

The two meshes I want to combine are defined in a seperate qml file, so I can call it within my Scene3D.

I think I've read all available solutions about problems with 3D under JFx on RPi and none of the following suits my needs. I had no problems with 2D applications. But when I try to run 3D program, all the 3D elements are gone. After this command:
