Qt + OpenGL Tutorial online

[ghorwin]

Hi all,

just wanted to inform you, that I've just finished a tutorial about Qt and OpenGL (including discussions of QOpenGLWindow, QOpenGLWidget, custom QWindow-based widgets etc.). Basic idea was to get an updated summary of all the tutorials and forum discussions around these approaches. Mind: focus is not on game development, but on CAD/CAM technical applications.

https://ghorwin.github.io/OpenGLWithQt-Tutorial/

The tutorial is in german (I made it for our master/PhD students at TU Dresden), but if there is sufficient demand for it, and google translator just isn't good enough for the job, I'll do an english version.

Github-repo (with all the source codes, BSD licensed) is here:

Cheers,
Andreas

Hi,

update: tutorial contains now discussion of the QOpenGLTexture and QOpenGLFramebuffer classes. Also, I found out that framebuffers with only a depth buffer (shadow map rendering) isn't working with QOpenGLFramebuffer, so you have to fall back to native OpenGL. For my part, the tutorial/feature test is now done.

Btw, anyone worked with Qt and VisualizationLibrary (https://visualizationlibrary.org) , yet?

Thank you for this tutorial.
I need to show tutorial_05 in QML side. I could not manage to do it. i read https://doc.qt.io/qt-5/qtquick-scenegraph-openglunderqml-example.html But it didn't help me.
Can you help?
