Qt provides support for integration with OpenGL implementations, giving developers the opportunity to display hardware accelerated 3D graphics alongside a more conventional user interface. These examples demonstrate the basic techniques used to take advantage of OpenGL in Qt applications.

OpenGL Window Example. This example shows how to create a minimal QWindow based application for the purpose of using OpenGL.

This example demonstrates easy, cross-platform usage of OpenGL ES 3.0 functions via QOpenGLExtraFunctions in an application that works identically on desktop platforms with OpenGL 3.3 and mobile/embedded devices with OpenGL ES 3.0.

It shows how to make use of Qt and its OpenGL related classes to create 3D graphics by using OpenGL’s pro-grammable pipeline. The tutorial provides many examples that demonstrate the basic features of OpenGL programming such as rendering, texture mapping, lighting, and so on.

A comprehensive discussion of many Qt Wrapper and convenience classes and functions to assist with OpenGL development. Includes discussion of best-practice approaches for many topics, including input handling and battery-efficient render-on-demand.

The Hello GL2 example demonstrates the basic use of the OpenGL-related classes provided with Qt. Qt provides the QOpenGLWidget class to enable OpenGL graphics to be rendered within a standard application user interface.

Jan 31, 2024 · Many of the simple OpenGL examples with Qt (including the QOpenGLWindow example shipped with Qt) use the old style of OpenGL that shouldn't be used any longer. Here is a tutorial that has updated the QOpenGLWindow example to modern OpenGL (3+).

May 24, 2016 · In this post I am going to share the source code and explain a very simple example project that can be used as a starting point for anyone who wants to begin using OpenGL in Qt. As it is seen in the picture, this program draws a single place on the screen and allows you to rotate it in all directions.
