What is Linear Workflow?
Linear Workflow is a term used in 3D computer graphics to describe a pipeline where the colors are managed from start to finish in an linear fashion. By linear, we mean that each color component is stored as a float value between 0 and 1. This includes the Red, Green, and Blue (RGB) color channels as well as the Alpha channel.
The advantage of using Linear Workflow is that it allows for more accurate color representation throughout the entire 3D visualization process. Colors can be accurately represented at each stage, from modeling to lighting to rendering. This results in final images that are closer to what our eyes actually see.
