NO… man… trust me… u heard of steven stahlberg? he is a god at 3d… and he states that ANYthing has a smooth edge. look at walls… are they sharp? no… curved at a radius of about a millimeter… THAT detail makes all teh difference. tank? straight? NO… it has edges made out of rough metal plating which is really hard to form and takes some beating up to get final positioned. the edges are rounded … not on purpose but as any draftsman as myself knows… when creating a mold for a product you must LEAVE some faces rough and rounded and those that really matter are shaved off… BUT those parts are always inside, engine wise usually.
so… MOST things do not have sharp edges… SOME do… but as i said… it doesnt look good because in real life everythign is smooth. if you think of it as an inch is small then u are in the wrong business =] 3d is down to the smallest possible increment. just tryin to help… but here… lookie at these.
notice the edges are almost ALL rounded.
now if i made those with sharp edges they woudl look like sh1t. instead i rounded most everythign using fillets. it creates more realistic ligting effects. ever look over a window sill and see teh sun’s rays casting through it kinda? thats because of imperfections in the surface and its almsot NEVER smooth surfaced and sharp edged. =] this is all in real life… you cna make things with sharp edges ie, knives etc… but those objects that are sharp are almost NEVER seen. when you walk into your kitchen… 98 percent of what you see is rounded… mostly for safety but also for look. countertops… EVEN if you just have a simple countertop the edges are bevelled and shaven off before finishing the kitchen. well thats about it… little lesson in realism…
here is my referrence for my statements so i dont sound like a babbling fool =]
more thoughts… here look at this image… www.optidigit.com/stevens/badguy.jpg
it shows a dood standing up and he has a weird lookin belt thingy… notice the edges… look sharp? nah… they are smoothed to the finest possible increment… its just a detail thing… if u want shabby work make sharp [god knwos it takes hours less time to NOT fillet and chamfer all the edges in a scene] but those who do make the big bucks =]
this one is harder to see but u kinda can
that girl is fake =] but still… look at her gun … edges are filleted extremely small… if this was not done then when renderred even teh most complicated meshes or nurbs turn bumpy and look like total crap. even with modern day raytracers and full screen A/A its not perfect.
and here: DONT STARE… look at the bolts and such on teh MECHANICAL part =]
all smoothed slightly.
well thats pretty much it… dont get me wrong… you can have a tight as$ scene with sharp edges but making them all SLIGHTLY rounded makes it millions of times better.
