Abstracts

1. Introduction to Qt 3D – Dr Sean Harmer

Target Audience: Developers or Managers wishing to get an idea of what Qt 3D is about and learn how to make some attractive applications with 3D content in the process.

Prerequisite: A basic understanding of QML would be useful. No prior OpenGL or 3D experience is required.

Qt 5.7 introduces the powerful new Qt 3D module that can be used to integrate 3D content into your Qt applications using C++ or QML. In fact, Qt 3D provides an extensible framework for soft realtime simulations, of which rendering is just one aspect. This 1 day training will introduce you to Qt 3D’s features and APIs, show what you can achieve with them, and how Qt 3D can be extended by the user and by the Qt 3D authors in the future.

Along the way we will introduce the Qt 3D renderer and input systems and how they are built on top of a flexible, highly threaded, Entity Component System (ECS) architecture that scales very well and is ripe for future additions. You will learn:

  • How to construct a basic Qt 3D application
  • About Transform hierarchies and Entities and Components ot make a scene graph
  • How to display 3D graphical content using geometry, materials, textures
  • How Qt 3D maps onto the graphics pipeline
  • How to extend Qt 3D to use your own custom geometry
  • How to write custom materials and shaders
  • How to completely control the Qt 3D renderer dynamically at runtime using the Frame Graph
  • How to integrate Qt 3D with Qt Quick to provide a 2D user interface
  • How to handle advanced input with Qt 3D
  • Future plans for Qt 3D and how to extend it yourself

2. Basic and modern CMake – Andreas Hartmetz

Target Audience: C and C++ Developers

Prerequisite: Experience with build systems
(well I guess – otherwise trainees will not know what problems even need
solving, so they won’t understand what the solutions are good for)

The best thing a build system can do is not get into the way.

CMake is the de facto standard build system for C and C++ outside of frameworks that require their own. It has earned this place by supporting the situations and special cases that arise in real projects.
CMake even has strong support for building Qt applications, and it’s a good alternative if you hit limitations in qmake.

This course will teach the basics of creating and building projects with CMake. In recent years, CMake has introduced some cleaner and more precise constructs. The course will focus on the new constructs where possible.

About the presenter

Software engineer at KDAB, Andreas Hartmetz has been contributing to KDE base libraries since 2007, when KDE switched to CMake for KDE 4.0. An expert on CMake, Andreas recently took the lead on a project successfully porting to CMake from a sophisticated GNU Make build system. He is the main author of KDAB’s CMake training material. Andreas studied Physics in Heidelberg and Berlin.


3 . Beyond code – Improved Quality through User Centric Development – Björn Balazs

Target Audience: Developer, Development Lead, Product Manager, Manager, Decision Maker interested in learning how users can be involved to boost a products’ success

Prerequisite: Being part of a product development team

Users ultimately decide about the success of your product – at the latest when they are supposed to use it. But, fear not: With this training we provide you with strategies for turning your users into allies early in the development process. These strategies will not only lead to better customer satisfaction, but also help to improve the development process itself.

Wondering how your product can benefit from the ideas behind Usability, User Centered Development, Design Thinking or Interaction Design?

With this introductory training you will not only understand the theory, but you will also take away tools and strategies you can directly introduce to your product development team back home. We will of course put a special focus on the challenges and opportunities that developing with Qt & QtQuick Technologies bring to the process.

Some Topics covered:

  • ISO 9241-210 or What is a User Centered Development Process?
  • Personas: Making Users actionable in the Development Process
  • What do users want? Getting User Feedback right.
  • Usability Testing: Guerilla vs. The Laboratory
  • Prototyping and How Qt can help.

4. Debugging and Profiling Qt development – Milian Wolff

Target audience: Developers who want to find and fix problems

Prerequisite: Knowing the basics of C++, Qt and QML

This training gives an introduction to various tools, which help developers and testers in finding bugs and performance issues.

The tools presented cover a wide range of problems, from general purpose debugging and CPU profiling to Qt specific high-level analyzers. Often, it is relatively simple to run a tool, but interpreting the results, or even just using some of the more advanced tools, requires deep technical knowledge.
The most important tools on all major platforms that Qt supports, i.e. Linux, Windows, Mac OSX, iOS and Android, will be covered:

Debugging:

  • General purpose debuggers: GDB, LLDB, Windows debugging tools
  • Memory error detectors: valgrind’s memcheck, Dr memory, AddressSanitizer
  • OpenGL: apitrace
  • Various Qt built-in features for logging, QML
  • GammaRay to investigate internals of Qt Applications

Profiling:

  • CPU: valgrinds’s callgrind, Linux perf, Intel VTune Amplifier, Instruments, Visual Studio
  • Heap memory: valgrind’s massif, heaptrack, Instruments, Visual Studio
  • OpenGL: apitrace, NVidia nSight, AMD CodeXL, Vivante vProfile

Testing:

  • Qt TestLib: unit tests and benchmarks
  • Static code analysis
  • Code coverage

7. Introduction to Modern OpenGL with Qt
– Giuseppe D’Angelo

Target Audience: Developers interested in learning the basics of OpenGL.

Prerequisite: A basic level of linear algebra will be assumed for this course (multiplying a matrix and a vector). Mathematics will be kept to a bare minimum so as not to get in the way of eye candy!

OpenGL is a central part of QtQuick2 in Qt 5 and also plays a key role in displaying the main content of many widget-based applications.

OpenGL has been around for many years and in recent times has evolved to shed much of its legacy baggage and better expose the underlying hardware. Modern OpenGL allows us to take full advantage of the enormous power and parallel processing power of today’s GPUs. Maximizing performance of OpenGL rendering requires us to understand how GPUs work and how to efficiently feed them with data.

Qt provides a number of classes to make life easier when working with modern OpenGL. This training will show you how to do the basic tasks associated with OpenGL rendering and will go on to show how to use Qt and OpenGL to achieve a number of rendering effects and algorithms. You will also learn how to write custom QtQuick2 items using the OpenGL and scene graph APIs.
