I want to make a Torus in Minecraft - I found the formula on the SK Wiki;
//g stone (0.75-sqrt(x^2+y^2))^2+z^2 < 0.25^2
This creates a vertical torus, extending the torus in the y plane.
What I want is a horizontal torus, along the ground. I have tried simply making a Torus as is and Flipping/Rotating it, but I am unable to get it into the horizontal plane this way, and unable to modify the formula myself to give me the shape I need.
