Shader

A shader is a small program that runs on a computer's graphics processing unit (GPU) to calculate and define the visual appearance of 2D or 3D objects in computer graphics. Shaders are crucial in the tech community as they enable developers to create realistic lighting, textures, and effects in various applications, including video games, simulations, and visual effects for film and television, making them a fundamental tool for game developers, graphics designers, and visual effects artists.
