Learning to create 3D applications can be an overwhelming task even for seasoned developers because of all the new terminology, visual concepts, and advanced math. To simplify the job, many developers use a framework like Qt 3D, which KDAB developed and contributed to Qt. In this paper, the first of 3 whitepapers, you will learn about the structure of a Qt 3D program – the nature of entities, components, and aspects, and how those are incorporated into the scene graph and frame graph. The Qt 3D Basics series is intended to help developers create highly polished Qt 3D applications, including descriptions of the technology components, the rationale behind their designs, and straightforward examples.

This paper outlines the sticking points migrating from OpenGL ES to OpenGL SC, with a summary of the code affected, the rationale for each change, and workarounds.

The C++ programming language is used for operating systems, web browsers, games, embedded software, autonomous cars, medical technology, and many other applications. In 2020, major companies such as Facebook, Google, Amazon, and many others relied on C++ to run their data centers, and likely they still do. Since its inception over four decades ago, C++ has expanded many times with performance, efficiency, and flexibility of use as its main design highlights. When C++20 became generally available in December 2020, we talked to a panel of C++ experts, evangelists, and devotees from both sides of the pond to understand a little more about C++ – its current position in the development community, its history, and its future. Much of what we learnt then is still relevant today.

New releases of the C++ language maintain incredibly strong backwards compatibility, making it easy to keep older C++ code working properly as standards march forward. C++11, C++14, and C++17 have transformed the C++ language making it as programmer-friendly as more recent languages but with many essential benefits that continue to make it the best choice for the most demanding software-engineering projects. Modernizing your C++ may be the best way to both improve your team’s efficiency as well as future-proof your software investment.

Vulkan 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, much like Direct3D 12 and Metal. This whitepaper, written in 2016 by Dr Sean Harmer, offers a fascinating quick-start primer on the nine things you need to know about this shiny new API.

This whitepaper is the first in KDAB's Software Development Best Practices series and covers the basics. Many of the tips will not surprise most professional software engineers, but if you’re just getting started, it can be a handy reminder. If you’re not already doing everything here, you should be.

Parts One and Two of our three part Qt 3D series focused on drawing a 3D model and accepting user input, which are necessary building blocks of 3D applications. For the last part, we’ll look at how to use Qt 3D and frame graphs to create some really sophisticated looking graphics, including how to implement multi-pass rendering.

Deciding on the various software components in your stack is a crucial step when creating your first embedded Linux device. You want to build a stack that meets your objectives now and brings continued value in the future. However, there are so many tools you can combine to build and maintain a successful product it can be challenging to know where to start. This whitepaper examines your choices for the entire software stack, from the OS to the application, and gives you things to consider at every step.

As we move towards ubiquitous computing, embedded software is becoming integral to everything from airplanes to toasters. This paper addresses the implications of this rapid expansion, highlighting important issues that need discussion and resolution within the industry. Explore the future of embedded software and its pervasive role in our daily lives!
