Some of the topics are presented with program examples in Java, LWJGL, OpenGL and GLSL.
These tools are also provided for working on the exercises.

The necessary mathematical basics will be introduced if required.

Target Audience

B.Sc.-students in their fifth semester, M.Sc.-students in computer science, mathematics, physics, etc.,
