Bringing software into a safety critical environment can be tricky, especially when using the complex APIs needed for modern 3D graphics. That’s what makes OpenGL SC (Safety Critical) so important: it bridges the gap between beautiful displays and functional safety, while trying to remain as close to existing embedded standards that we all know and love. OpenGL SC will only become more prevalent in embedded graphics work as industries increasingly try to merge safety conscious methodologies with user-friendly interfaces.…

Writing Code That Won’t Kill A Functional Safety Source Book
Functional Safety is the term used for systems designed to minimize risk to human health. But there’s a dilemma in today’s tech-driven world.
We are more reliant than ever on software to control our planes, trains, cars, and boats, to operate our medical equipment, to process our food, to clean our water, and to power our homes. If these systems don’t function properly, they have the ability to injure, or even kill us. Meanwhile software complexity continues to increase exponentially …
Physically Based Rendering (PBR) in 10 minutes A guide for Qt developers
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 projects?
In a sentence, PBR replaces common shortcuts for rendering surfaces with methodologies rooted in the physical world. Sound intriguing? Download our …
Nine Steps to Vulkan Literacy
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 standards. Like OpenGL, Vulkan targets high-performance real-time 3D graphics applications such as games and interactive media, but offers higher performance and lower CPU usage, …
C and Its Offspring: OpenGL and OpenCL – Parts 1 & 2 OpenGL Speeds High-End Graphics for On-Chip GPUs - by Sean Harmer
An in-depth look at improving the visual quality and computational throughput of systems with OpenGL, from a KDAB expert and the maintainer of Qt 3D, writing for the USA’s premium magazine for embedded computing: RTC magazine.…
Embedded’s Gone Cute by Rafael Roquetto
KDAB’s Rafael Roquetto lays it all out as to how and why Qt is the way to go for modern user interfaces in the embedded world in RTC magazine’s May digital issue, just published on-line.
With a potted history of the User Interface to date and a clear descriptions of Qt’s wide range of APIs and functionality (including examples), this is a must for anyone interested in Qt on embedded. You can check it out here:
