Raymarching SDFs (Signed Distance Fields) is slowly getting popular, because it's a simple, elegant and powerful way to represent 3D objects and even render 3D scenes. But the technique has been around for a long time. The first paper I found describing implicit functions and performing boolean operations by combining them with the min() and max() operators is from 1972 by A.Ricci and by B.Wyvill

Intro Here you will find the distance functions for basic primitives, plus the formulas for combining them together for building more complex shapes, as well as some distortion functions that you can use to shape your objects. Hopefully this will be useful for those rendering scenes with raymarching. You can see some of the results you can get by using these techniques in the raymarching distance
