What is OpenGL?

OpenGL is a cross-platform, low-level API for rendering 2D and 3D graphics. It is widely used in the industry and academia for developing applications such as video games, simulations, virtual reality, computer-aided design, and scientific visualization. OpenGL allows you to access the graphics hardware of your computer and control how pixels are drawn on the screen.

OpenGL is not a programming language, but a set of commands that you can use in your program to specify what you want to draw and how. You can use OpenGL with any programming language that supports it, such as C, C++, Java, Python, etc. However, you need to have some basic knowledge of linear algebra and geometry to understand how OpenGL works.

What are the benefits of learning computer graphics through OpenGL?

Learning computer graphics through OpenGL has several benefits:
