OpenGL Extensions

OpenGL extensions are additional features or capabilities that go beyond the core graphics standard. They allow developers to access new or specialized graphics functions tailored to specific hardware or needs, enabling more advanced or optimized rendering. Think of extensions as optional upgrades or add-ons that enhance what OpenGL can do, often providing access to the latest graphics technology without waiting for a full version update. They ensure flexibility and future-proofing, allowing software to leverage new hardware improvements and unique features offered by different graphics cards and devices.
