A kind of variable, used by a fragment shader, that interpolates values across a primitive, so as to produce gradient effects etc.
"The fragment shader utilizes varying coordinates to smoothly blend colors across the triangle and create a realistic lighting effect."
"The varying opinions in the room made reaching a decision difficult."
Usage: In computer graphics programming, use the noun varying specifically when referring to data passed from vertex shaders and interpolated automatically across triangle surfaces in fragment shaders. Do not confuse this technical term with general synonyms like "variable" or "fluctuation," as it describes a specific memory scope within the GPU rendering pipeline rather than any changing value.
present participle of vary
