Implementing set palette defined from gnuplot in FragmentShader
up vote

I want to reproduce the "set palette defined" command from gnuplot for a fragment shader (glsl) in order to color my shaders. I found this very useful site https://github.com/kbinani/colormap-shaders where there are many glsl codes implemented for matlab and gnuplot examples but they implemented just the rgbformulae from gnuplot.
I would like to render something that in gnuplot would be like "set palette defined ( 0 "orange", 1 "white", 2 "blue") ". I don't understand at all how this "palette defined" works, so I cannot extract any mathematical formula like kbinani is using. Is there any place where I can find that kind of fragment?
