GLSL ES

GLSL ES (OpenGL Shading Language for Embedded Systems) is a specialized programming language used to write shaders—small programs that run on Graphics Processing Units (GPUs) in devices like smartphones and tablets. These shaders control how graphics are rendered, creating effects such as lighting, textures, and colors in real-time. GLSL ES is optimized for performance on resource-limited devices, allowing developers to produce rich, visually compelling graphics while maintaining smooth performance. Essentially, it’s a tool that helps make complex visual effects possible efficiently on embedded hardware.
