So I see a lot of modelers cleaning up polydisks by eliminating the converging triangles from a center point (middle), to to making new edges that pass back and forth across the disk(left). This only saves a few polys, so i was wondering, is there another reason for doing this? Does a high amount of of polys converging on a single point (far right) cause problems in realtime rendering or something? Or is the center one ok? I kinda like having the center point for reference in lining it up with other objects.
