how to draw a torus with grid? I want to model a torus with grid, i.e torus code in topology quantum computation, just like followin, but I do not know how to draw grid.
Maybe using texture might be helpful, but are there any other ways?
Did you try using a wireframe node or modifier. You may be able to duplicate the torus and then apply the wireframe to the outer torus if you want it to look more 3D. But you can also try the wireframe node.
