## Summary
The OpenGL ES Shading Language (GLSL ES) is a programming language designed for writing shaders in embedded systems, particularly mobile and low-power devices. It is a subset of the OpenGL Shading Language (GLSL), optimized for efficiency and compatibility with OpenGL ES. Developed by the Khronos Group, it enables developers to create visual effects for applications like games and graphical interfaces on platforms such as smartphones and tablets.
