OpenGL (Open Graphics Library) is a cross-platform, open-source graphics API (Application Programming Interface) that allows developers to create 2D and 3D graphics. Initially developed by Silicon Graphics Inc. (SGI) in the early 1990s, It is used for various applications, including computer-aided design (CAD), video games, scientific visualization, virtual reality, and flight simulation. OpenGL has since become a standard in the graphics industry. It provides a robust framework for rendering vector graphics, enabling the development of high-performance visual applications. In this post, we’ll explore the significance of OpenGL in CAD application development, its benefits, and how it enhances the capabilities of these critical tools.
