programmable shaders

Programmable shaders are customizable programs used in graphics processing units (GPUs) to control how images and effects are rendered on a screen. Unlike fixed-function hardware that has limited, predefined functions, shaders can be written and adjusted to create specific visual effects such as lighting, textures, and shadows. This flexibility allows developers to design detailed, realistic graphics and animations tailored to their needs, enhancing the visual quality and performance of video games, simulations, and other graphics-intensive applications.
