Low Level Graphics & OpenGL
1 like247 views
The document discusses graphics rendering technologies such as DirectX and OpenGL, outlining their functions and features within game development. It explains concepts like rasterization versus vectorization, shaders, and pixel buffering, emphasizing the importance of graphics APIs and game engines. Additionally, it highlights the role of SDL2 as a cross-platform game development library that supports window creation and input handling.
