I am new to the world of computer science. I learnt C language last year in my university. I also have a basic knowledge of OOP concepts and C# I want to learn Computer Graphics. I found this book named "Computer Graphics Using OpenGL by F.S. Hill" in the Library. The copyright year of the book is 1990. I was wondering, would the info in this book be too old for today? Also, is OpenGL an old software? Is it still used? What are other platforms for computer graphics apart from OpenGL?
