shader languages

Shader languages are specialized programming languages used to create visual effects and textures on digital images, especially in video games and graphics applications. They allow developers to control how surfaces look—like adding shadows, reflections, or colors—by giving detailed instructions to graphics hardware. Think of them as scripts that tell a computer how to render realistic or artistic visuals efficiently. Common shader languages include GLSL and HLSL, which work within graphics APIs to produce lifelike scenes and effects in real-time.
