Getting rid of "herringbone" pattern
-
I was getting ready to post this model, and as I was taking some screenshots of it I noticed a very ugly herringbone pattern on the rim around the dish. Also in parts of the fence, and the siding on the towers looks all funky
the rim is comprised of a series of ribs
the fence is just a fence
and the siding is just normal siding
Any way to get rid of this effect? Or at least minimize it?
thanks in advanceSteve

that's a phenomenon known as 'moire' and it's problematic with most digital imaging processes (digital photography etc)
basically, your options are: (other than using a different viewpoint or different/wider spacing of the objects)
• print it- printers have very fine resolution and in many cases, the print will not be riddled with the effect.
• selectively blur it out in an image editor.. it will lose detail in those areas, obviously, but it's often better than including the eye-catching pattern.
edit- • rendering the model, in certain circumstances, may help eliminate it as well..

It's why back in the old days you didn't want to wear stripes on TV.

Thanks. None of those options are appealing to me so guess I'll just have to live with it

yeah, I remember when that was a big deal, especially on the news shows. I think they called it a herringbone pattern back then.

yeah.. probably the best bet.
chances are, you look at pictures on screen which show this effect much more often than you may think.. our minds tend to filter some of it out for us.. but when you're scrutinizing your own work, it pops out more readily

Hey, it was worth a shot. And you never know till you ask, right?

Mind boggling modelling. Complexity like that'd be nice rendered like Tchernikov. -

right. of course.
and the only reason i know some stuff about it is because i did the same thing in the past.
but maybe find some comfort in realizing it's not a sketchup problem, or software problem, and it's only sort of a hardware/technology problem.. (current technology makes it more prevalent in cases.. but it's not the cause).. it's a natural 'problem'.
we see these patterns with our own eyes on real world objects.. often on window screens and certain fabrics.

Thanks. I'll render it just as soon as I learn how (I figure about the second Tuesday of next week

Interesting. But my model still looks like crap

haha

WHAT!...I'm still staring at the thing

You can also export it at a higher resolution (with anti-aliasing turned off), then use Photoshop or similar to downscale the image. Different scaling algorithms will help mitigate the moire. I think the default bicubic resize works pretty well to do that.
-
It looks superb!! I cant even see the moire effect on my monitor at all.
-
I can cope alright with the Moire, it's that greasy thumbprint on the manual brake handle of the right hand roller mechanism of the eastern stanchion that is driving me nuts.
-
You sure make SketchUp output look good. IDK how...
-
+1 on Peter's remark
Your untouchable for raw SU output.

You noticed that, too? I didn't want to be picky, but, you're right, it is annoying on an otherwise fairly decent model

WHAT!...I'm still staring at the thingThanks, but I only got it about 70% finished before threw in the towel.
If you want to see a seriously amazing model of it, check it out here http://www.foundation3d.com/forums/showthread.php?t=9381%26amp;page=8 starting around page 8 or so.
His work makes mine look like a tinkertoy. Incredible detail! In fact, I used some of his photos as reference for mine.@andybot said:

Hmmm... I've never used the export tool, just captured screen shots.
Ok, I gave it a try, but could not see any options as far as choosing an export resolution.@cadmunkey said:

Thanks. Can I buy your monitor?

Hey, it took hours to get that greasy thumbprint to look just right!

Just mess around with the shadows is all I do (much easier now with 2015)

Much appreciated, but like I said, I don't do anything special, just try to use the shadows to my advantage.

Alright, I'll delete the greasy thumbprint before I post the dang thing!

When you select the Export --> 2D graphic, in the bottom right corner is the "options" button. This allows you to set resolution when you uncheck "use view size". The AA checkbox is there too.
