WebJul 19, 2024 · One of the vertices in an output primitive is designated the "provoking vertex". This vertex has special meanings for the primitive. For example, when using flat-shading on output variables, only outputs from the provoking vertex are used; every fragment generated by that primitive gets it's input from the output of the provoking vertex.
