OpenGL ES Programming

Students learn with interactive and hands-on sessions about graphics hardware, shading, data management, all through the modern OpenGL ES API. The course covers OpenGL ES 2.0 and the OpenGL ES Shading Language as well as the similarities and differences between OpenGL ES and desktop OpenGL 3.x/4.x. Topics include both the core languages and extensions such as those for double precision and interfacing with OpenGL 3D graphics buffers.

Student Requirements:

• Students are required to bring a laptop configured with their environment and the OpenGL ES development environment (iOS or Android)
