LLC501: Programming with OpenGL

This course is tailor made for the wannabe 3D graphics enthusiast. The course initiates a person with 3D programming using OpenGL and provides a foundation of OpenGL concepts using which you can begin exploring the capabilities of OpenGL and write 3D enabled applications. At the end of the course you would be able to create 3D scenes, orient objects in the scene, place lights in the scene, apply texture and use transparent objects in the scene. The course has a hands on approach to teaching OpenGL in that the participants will take part in designing and implementing a C++ library on top of OpenGL to help create simple 3D scenes.

Sound knowledge of C and C++. Knowledge of Qt, (LLC105) would be a plus point. Basic knowledge of Trigonometry, Matrices and Algebra and other related math domains.

Target Audience
The course is targeted at developers who have not worked or worked little on 3D programming libraries. This course is a must for developers interested in learning about OpenGL and getting started with 3D Programming.

Duration: 3 days (Full-time)
