State-of-the-Art OpenGL with Qt

This 5-day, hands-on course provides an introduction to modern OpenGL using programmable shader pipelines. It introduces the use of the Qt framework for infrastructure and support to quickly achieve highly efficient and visually appealing, state-of-the-art, interactive graphics applications. The class covers basic topics such as handling of geometry, graphics pipeline, transformations as well as advanced topics such as vertex, fragment and geometry shaders and their applications. Qt and C++ based Labs are designed to let participants experiment with OpenGL easily in order to deepen the understanding of the material.

Course Availability: On-site, Open Enrollment
Duration: 5 days

Course Prerequisites

  • Working knowledge of C++ programming

  • Basic knowledge of geometry

  • Previous experience with OpenGL and/or Qt is not required

Mandatory computer requirements

Course Outline

This course will be roughly divided into four 90 minute sections and each section will target an even mix of lecture and labs. The goal is to give students plenty of time to experiment with the lab material.

The class uses Qt-5.9.1 and is based on Qt's OpenGL integration classes QOpenGLWidget and QOpenGLWindow. 
Course material is divided into four 90 minute sections per day and each section will target an even mix of lecture and labs. The goal is to give students plenty of time to experiment with the lab material.
