hello i'm currently working on the free dog tutorial provided by simplymaya ....and during the tutorial...there are sections of the polygon model where there are extra edges....i'm wondering is there any harm to leaving unessesary edges in the model....is removing them purely for asthetics of the wireframe? or does it serve some purpose...


second question....while working on the polygon part there are times where there are three sided polygons.....just wondering if three sided polygons are bad versus four sided? again is it purely wireframe asthetics or does it serve a purpose such as smoother texture application?


sorry for being a noob...

thanks in advanced for any answers...
