[accordion autoclose=”true” tag=”h6″ clicktoclose=”true” class=”acc”] [accordion-item id=”item-2″ title=”Introduction to Qt 3D”]

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 introduced 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 or 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

Why learn Qt 3D?

Integrating 3D content in applications is becoming a clear trend in many fields and is likely to become even more important in the future with the growth of Virtual Reality and Augmented Reality. Qt has always allowed you to integrate with OpenGL fairly easily, but managing the rendering code itself was still a very challenging task, often limited to a few specialized team members. With Qt 3D, you can bypass that challenge as the heavy lifting has already been done.

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 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 several rendering effects and algorithms. You will also learn how to write custom QtQuick2 items using the OpenGL and scene graph APIs.

Why learn Modern OpenGL?

OpenGL is the industry standard for high performance graphics and computation on desktop, mobile and embedded platforms. Whether the requirement is visualizing large data sets, creating engaging user interfaces or breathtaking real-time visuals, getting the topics covered in this course is essential. [/accordion-item] [accordion-item id=”item-7″ title=”Introduction to Multithreading with Qt”]Target Audience: Qt Developers interested in multithreaded development. Prerequisite: Existing Qt knowledge. Basic understanding of multithreaded programming is also an advantage.

With more and more cores in computers, multithreaded programming is becoming increasingly important for developers.

Qt offers several mechanisms for multithreading, however, it is up to you to decide which to use when so that you steer clear of common pitfalls. This course offers guidance on how to choose.

Why learn about Multithreading with Qt?

This training will introduce you to multithreading concepts in general, tell you about the different mechanism in Qt, and discuss best practices and common pitfalls. [/accordion-item] [accordion-item id=”item-8″ title=”Introduction to Model/View Programming with Qt”]Target Audience: Qt developers interested in model/view either from QML or from Qt Widgets. Prerequisite: Existing Qt knowledge.

A key ingredient in successful software development is the separation of presentation and business logic. Everyone knows that. A larger part of most applications is a list of things, and for those, Qt offers such separation using a model/view framework.

This presentation will introduce this framework and tell you how to develop models independent of whether they are to be displayed in a C++/Qt application or in a Qt Quick application.

The training dives into subjects such as:

  • The API to implement for use in a 1-dimensional list, a 2-dimensional table and a tree view
  • What model indexes are all about
  • How to successfully implement a proxy model
  • How to debug your models
  • How to implement models in C++ that are displayed in Qt Quick

Why learn Model/View Programming?

Model/View Programming teaches efficient displaying and manipulation of data sets of unknown sizes and independent of data source. It allows applications to work with hundreds of thousands of records, from in-memory data, databases or servers.

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.

Why learn CMake?

CMake has broad functionality that covers many real-world problems. Learning CMake enables you to solve advanced build requirements. This includes cross-platform builds, feature detection based on platform or available libraries, build-time configurable feature switches and custom build steps.[/accordion-item] [accordion-item id=”item-11″ title=”Advanced QML”]Target audience: Experienced QML developers targeting embedded and/or mobile platforms. Prerequisite: A functional knowledge of QML is needed. Developers with more than one year of Qt/QML experience will also benefit from this course which is regularly updated.

This course is designed to take programmers who already know QML to a deeper level of functional understanding.

Why learn Advanced OpenGL?

In this course, we introduce some of the most widely used and generally applicable rendering techniques, as well as explaining the costs of different graphic operations to get the best from available hardware resources. You will learn how to effectively increase your hardware performance with OpenGL.[/accordion-item] [accordion-item id=”item-13″ title=”What’s new in C++14 and C++17?”]Target Audience: C++ developers who want to know more about the new features introduced in C++14 and C++17. Prerequisite: Knowing the basics of C++11 is a requirement, though more advanced topics will be explained as needed.

Starting with C++11 released in 2011, the C++ language and standard library have steadily evolved. At the end of this year, the new C++17 standard, already supported by major compilers, is going to be released, adding a sizable amount of useful new features.

In this training, the most useful of the new features introduced in C++17 and its predecessor, C++14, will be presented. In cases for which these features depend on features introduced in C++11, these will be refreshed as well.

New library features being presented include the new types std::any, std::optional and std::variant, the new parallel algorithms and std::string_view. The new language features range from ways to improve template code with fold expressions, constexpr if and class template deduction over improvements of lambdas to structured bindings and initializers in if and switch statements.

Why learn what’s new in C++14 and C++17?

C++ is the language that powers most applications written with Qt. To make the most out of the language, developers need to know its capabilities and pitfalls, and keep up with the incremental changes done in new releases. Doing so rewards them with ways to write easier, faster, cleaner and safer code[/accordion-item] [/accordion]
