Integrating custom OpenGL rendering code, for example to show 3D models, with Qt Quick is a popular topic with Qt users. With the release of Qt 5.0 the standard approach was to use the beforeRendering and afterRendering signals to issue the custom OpenGL commands before or after the rendering of the rest of the scene,

Many Qt users encounter a need to integrate GPU compute solutions into their Qt-based applications. What is more, with the advent of compute API implementations and powerful GPUs on embedded devices, using OpenCL or CUDA on an Embedded Linux device is a reality now. In a previous post we looked at NVIDIA’s Jetson TK1 board

Posted in Compilers, Embedded, Graphics, OpenGL, QPA

NVIDIA’s Jetson TK1 is a powerful development board based on the Tegra K1 chip. It comes with a GPU capable of OpenGL 4.4, OpenGL ES 3.1 and CUDA 6.5. From Qt’s perspective this is a somewhat unorthodox embedded device because its customized Linux system is based on Ubuntu 14.04 and runs the regular X11 environment.

Posted in Embedded, Graphics, OpenGL, QPA

The upcoming Qt 5.5 has received a number of improvements when it comes to running without a windowing system on Linux. While these target mainly Embedded Linux devices, they are also interesting for those wishing to run Qt applications on their desktop machines directly on the Linux console without X11 or Wayland. We will now

With the Qt 5.4 update for Qt for Device Creation it is now possible – on certain embedded systems – to run Qt applications on top of a Wayland compositor by relying only on the provided reference images without any additional modifications. While the stable and supported approach remains eglfs, the lightweight platform plugin that
