Physics Based Rendering (PBR) is the latest and greatest trend in real-time rendering yielding much more visually believable images than the traditional Phong or ad-hoc lighting models. The underlying concept is that the shaders should use physical principles in the encoded models – chief of which are conservation of energy and the Fresnel effect. PBR […]
Hello! This is a small wrap-up fromQtCon, the biggest Qt event in Europe in 2016, that happened at the beginning of September. At QtCon the Qt community joined forces with the KDE, FSFE and VideoLAN communities, to create an exciting event in the spirit of open collaboration and participation amongst projects. During QtCon many KDAB […]
Hello, and welcome to the usual appointment with a new release of Qt! Qt 5.7 has just been released, and once more, KDAB has been a huge part of it (we are shown in red on the graph): In this blog post I will show some of the outstanding contributions by KDAB engineers to the […]
Some of you may know that Qt 3D is going strong almost entirely due to the work of the KDAB team, led by Dr. Sean Harmer and Paul Lemire. You can read all about its near demise and ultimate rescue here – it’s quite a story, and started with the release of Qt 4. Now […]
If you happened to be at the NVIDIA GTC conference last week, you may have seen a Qt demo we developed showing a Dodge Viper in the Toradex booth. If that Viper looked especially cool, that’s partially because it was displayed using Physically Based Rendering (PBR). Alright… what exactly is PBR, and can I use it in my […]
Qt 5.6 has just been released! Packed with incredible new features, 5.6 is also the first long term support release of Qt: it will be supported for the next 3 years, giving developers a solid foundation for their current and upcoming projects. Once more, KDAB is confirmed to be the largest independent contributor to Qt, […]
Demonstrates the use of Qt 3D using the QML API to create a high quality, animated 3D visualisation application. The demo shows Qt 3D’s ability to use custom shaders that implement a metal-roughness physics based rendering (PBR) pipeline. The PBR shaders coupled with specially crafted material textures and environment maps gives a very realistic simulation […]
No, this isn’t about Star Trek. If you’ve accidentally stumbled onto this blog to learn about the language of Spock’s homeland, try here instead. Vulkan (spelled with a “k”, not a “c”) is a powerful new 3D graphics API from the Khronos Group, the same consortium that developed its spiritual predecessor, OpenGL, and other related […]
Back in November, Apple released the latest generation of it’s Apple TV product. Besides the slightly improved hardware, the true new feature is the OS which is now officially based on iOS and comes with the dedicated SDK and App Store! So we started investigating what it would take to port Qt to tvOS and […]
In the last blog post we gave a very high level introduction to the Qt Quick 2 renderer. We also showed how various signals are emitted by the renderer during the synchronization and rendering steps. In this blog post we’re going to discuss those signals and show how they can be used to implement overlays […]
