edit v.0.6   Shader Fundamentals and Rendering Pipeline Shaders are small programs (with a “.shader” extension in Unity, and .usf/.ush in Unreal) that determine how surfaces interact with light . They perform mathematical calculations and execute a set of instructions (commands) to compute the color of every pixel covering an object . In essence, a shader tells the GPU—whose thousands of small, efficient cores are optimized for parallel processing—how to render objects based

Compute Shaders are specialized tools that enable massively parallel computations on the GPU, bypassing the traditional rendering pipeline. They’re ideal for tasks like real-time texture generation, physics simulations, and complex data processing.
