I’ve got one rendering right now. Everyone, hold onto your pants!
That thing is awesome!!! I just made a render of it, it looks great! How did you keep the rows so neat?
The way I did it is
- spinned a dot to get a ring
- Extruded and scaled slightly; repeat; --to get multiple concentric rings forming a disk
- Ctrl + / Rotate / 1 degree; repeat; --to have the ribbons slightly twisting
- Rotated to a side view and…
Ctrl - / Rotate (between 0.5 and 1.5 degrees) / G to move; repeat.
to have them curve around.
Essentially, it boils down to iterations of Ctrl + or Ctrl - and simple operations. There must be a better way of doing it but I’m lazier to learn new things than I am to do things the hard way
