Objectives

• Why C++ and OpenGL

• - C++ is the dominant language for visual computing and (the core of almost every scientific softwares in general)
• \(\Rightarrow\) You will use (at least - if not develop) library that are coded in C++ underneath.
• • - Maya, 3DStudio, Houdini, Catia, Unreal Engine, etc.

• - OpenGL is the low-level base for real-time CG.
• • You may use higher-level framework later (Unity, Unreal, etc.)
• - However, OpenGL is everywhere underneath (/direct3D on Windows)

• => Give you (remind you) the fundamental low-level concept on which other tools are based
• => Explains origin of keywords, working behavior, you may find in high level libraries
• • shaders, vertex, normals, phong, transform, etc
