Introduction to Computer Graphics: Course Overview and Resources

This course offers a comprehensive introduction to Computer Graphics, covering software, hardware, and diverse applications using a top-down approach. Participants will learn through shader-based OpenGL, incorporating OpenGL 3.1, OpenGL ES 2.0, and WebGL. Solid programming skills in C or C++ and knowledge of data structures, including linked lists, arrays, and geometry, are prerequisites. Key resources include the OpenGL Programmer's Guide and various online platforms. The course outlines topics from basic architecture to advanced rendering techniques.
