Shaders

Shaders are small programs that run on a GPU (Graphics Processing Unit) to control the rendering of graphics in real-time applications like video games, simulations, and visual effects. They define how vertices, pixels, or other data are processed to produce colors, lighting, textures, and other visual elements. Shaders are essential for creating complex and realistic graphics in modern computer graphics pipelines.

Also known as: Shader programs, GPU shaders, GLSL shaders, HLSL shaders, Shader code

Why learn Shaders?

Developers should learn shaders when working on graphics-intensive applications, such as game development, 3D modeling, or data visualization, to achieve custom visual effects and optimize performance. They are crucial for tasks like implementing advanced lighting models, post-processing effects, or procedural generation of textures, as they leverage GPU parallelism for high-speed rendering. Knowledge of shaders is also valuable in fields like virtual reality, augmented reality, and scientific simulations where real-time graphics are required.
