Hi Guys, So assuming I'm modelling in modo and hit the subd button and want a perfect circle. Should I be using a 6 sided polygon or 8 sided polygon if I want a perfect circle? Thanks
I believe Modo uses a flavor of Catmull–Clark subdivision, which will never give you a perfect circle, but most of the time, I feel like 32, 64, 128 is good enough, depending on the size, scale, and how close it will be to the camera.
Agreed with the above. Smoothing algorithms in use won't give you a mathematically perfect circle, if, for no other reason, than you'll need infinite subdivision levels to get there. I do find that multiples of 4 pointed shapes tend to give good results.
