Continuing our blog post series about the rewrite of Qt3D. One of the biggest driving factors behind the design of Qt3D 2.0 is the ability to configure the renderer in order to accommodate custom rendering techniques. In this blog post I will explain how to render a scene in Qt3D with shadows.

Overview of Qt3D 2.0 – Part 2
An Example of Rendering with Qt3D In the previous article we learned about the requirements and high-level architecture of Qt3D 2.0. In order to put some of this into context and to give you a concrete example of how it looks to draw something in Qt3D using the QML API, we will now briefly show […]
Overview of Qt 3D 2.0 – Part 1
by Sean Harmer of KDAB Back in the days when Qt was owned by Nokia, a development team in Brisbane had the idea of making it easy to incorporate 3D content into Qt applications. This happened around the time of the introduction of the QML language and technology stack, and so it was only natural […]

Introduction Back in the days when Qt was owned by Nokia, a development team in Brisbane had the idea of making it easy to incorporate 3D content into Qt applications. This happened around the time of the introduction of the QML language and technology stack, and so it was only natural that Qt3D should also […]
SlideViewer and the Display Window
Introduction Following on from the previous articles on SlideViewer, we shall now investigate another piece of the puzzle towards making SlideViewer usable in practise. Namely, getting the content rendered from our domain specific language and on to the screen or projector for the audience to marvel at. Those of you that have ever presented at […]
OpenGL in Qt 5.1 – Part 5
This article concludes our series on what is new in Qt 5.1 with respect to OpenGL. Earlier articles in this series are available at: Part 1 Part 2 Part 3 Part 4 More shader stages In Qt 5.0 the QOpenGLShader and QOpenGLShaderProgram classes only had support for Vertex and Fragment shaders. Qt 5.1 will include […]
OpenGL in Qt 5.1 – Part 4
This article continues our series on what is new in Qt 5.1 with respect to OpenGL. Earlier articles in this series are available at: Part 1 Part 2 Part 3 OpenGL Debug Output The traditional way to debug OpenGL is to call glGetError() after every GL function call. This is tedious, clutters up our code, […]
OpenGL in Qt 5.1 – Part 3
This article continues our series on what is new in Qt 5.1 with respect to OpenGL. If you haven’t already seen them, you may be interested in reading Part 1 and Part 2. Timer Queries OpenGL on the desktop exposes a very useful tool in the shape of timer query objects. These can be used […]
OpenGL in Qt 5.1 – Part 2
Qt has QOpenGLBuffer to manage OpenGL buffer objects like per-vertex attribute data and element index buffers. OpenGL also has a container type call Vertex Array Objects managing vertex buffer objects.
OpenGL in Qt 5.1 – Part 1
Firtst in a blog series that shows how to use OpenGL with Qt 5. We shall take a quick look at Qt’s historical support for OpenGL and then describe the first batch of new features in Qt 5.1 that enhance Qt’s OpenGL
