I’m a graphics programmer and I use a physical one fairly often while debugging shaders With rendering code I find a lot of the time you have to draw it out on paper to understand what it is doing/how it works Typically simple calculations involving trig/vectors I find it easier to have a physical one rather than flipping back and forth between paper/computer
