ronll Posted May 7, 2008 Share Posted May 7, 2008 When you see an image, maybe at small scale on the web, what clues do you look for to tell if its a photo or a virtual image? On exteriors, I usually look for patterns in the concrete sidewalks or streets, or anything that is slightly out of line with perspective rules such as a tilted lightpole. Saw one today that I thought was an image until I looked at the fire hydrant which had its base flange a few inches above grade where it hadn't been backfilled yet. Another clue is stakes holding up newly planted trees. Don't think many of us would put those in a rendering, but maybe . Any others? Link to comment Share on other sites More sharing options...
aaron-cds Posted May 7, 2008 Share Posted May 7, 2008 I think it's easier to tell exterior images are CG vs. interiors. I can only think of a handful of Viz companies doing exterior images where you really can't tell and they're usually doing a 3d model merged into a professional photo. Here's an exterior that's impossible to tell until you see the displaced grass in one of the close-up images - http://www.evermotion.org/vbulletin/showthread.php?t=63778 Link to comment Share on other sites More sharing options...
ronll Posted May 7, 2008 Author Share Posted May 7, 2008 Yup. I've seen those images many times and marveled over their beauty. Unfortunately the one spoiler is in the image with the large tree in the foreground where it looks like the main branches have been glued to the trunk. The bark patterns simply don't work there. But I hasten to add those are incredible images. Link to comment Share on other sites More sharing options...
aaron-cds Posted May 7, 2008 Share Posted May 7, 2008 Yeah, I saw that too. It's like a Monty Python technique In my renderings, I throw in obvious mistakes in each one so people can tell they're not real photos (that's my excuse for mistakes, anyway) Link to comment Share on other sites More sharing options...
ronll Posted May 7, 2008 Author Share Posted May 7, 2008 Wasn't it the Navajo rug weavers that would put in an obvious mistake so as not to anger the gods with perfection? That's my excuse. Don't want any gods angry because I'm trying to compete with them . Link to comment Share on other sites More sharing options...

amer abidi Posted May 7, 2008 Share Posted May 7, 2008 lolllll matt..so true! in interiors i look for constructional detailing.. you know? hinges in cupboards doors, screws in light switches, rubber sealants in windows..and well, it's almost always CG when you see the barcelona chair! as for exteriors, it's the shadows... there is still something not wuite right about CG exterior shadows, no matter how high your FG or GI settings, and no matter how long it takes to render. my 2 pence =) Link to comment Share on other sites More sharing options...

ikinman Posted May 7, 2008 Share Posted May 7, 2008 That nice.ies file gets around , just about as much as this guy. I was using that guy in the mid nineties. He was part of an old Imagecels library. That company used to license their people images as well, so he (and others) ended up in Lightscape Libraries, ArchiCad, etc. It would be fun to know who these people all are, as they have appeared in tens of thousands of architectural renderings over the past decade or two. -Ian Link to comment Share on other sites More sharing options...

Be funny if someone could track him down, kinda like a 'where are they now' for viz nerds. Link to comment Share on other sites More sharing options...
Adrian Bold Posted May 8, 2008 Share Posted May 8, 2008 lolllll matt..so true! as for exteriors, it's the shadows... there is still something not wuite right about CG exterior shadows, no matter how high your FG or GI settings, and no matter how long it takes to render. my 2 pence =) This might have something to do with relying on Vray. -Still haven't seen a good render from it that can balance shadows properly and yet to be proven otherwise... but then again, it's often a request from architects to fudge shadows to be less realistic and vray appears to do this nicely at the expense of believability. the other items, esp the barcelona, shows how online free model downloads or 3Dworld mag cd contents can be abused. I remember awhile back we required one to add to a scene and whilst we modelled it from scratch like most of our library (little support for maya files out there) we'll cringe if we ever have to use it again. Whats this nice.ies and cedfence.jpg your going on about? Link to comment Share on other sites More sharing options...
Nic H Posted May 8, 2008 Share Posted May 8, 2008 Nice.ies is a distinctive ies light pattern that looks quiet 'nice' and CEDFENCE is a timber plank texture that comes with 3Dmax. I used to use nice.ies all the time. Link to comment Share on other sites More sharing options...

Fran Posted May 9, 2008 Share Posted May 9, 2008 On interiors, it's cg if a woman's shoes are left on the livingroom floor. We just don't do that in real life. Not only that, but we will nag our men and children to put their shoes away as well. Link to comment Share on other sites More sharing options...
aaron-cds Posted May 9, 2008 Share Posted May 9, 2008 In addition to the shoes, if you put a half naked polygon woman in your scene looking out a window, uhh, it's cg. Link to comment Share on other sites More sharing options...
Fran Posted May 9, 2008 Share Posted May 9, 2008 Good point Aaron. LOL! I was saying to EBIII the other day that it's funny when there is a cg person in a scene walking full-stride into a wall. Link to comment Share on other sites More sharing options...
