WindLight Water - Cannery Bridge (tilt shift)Suspicion

I suspect WindLight behaves / looks seriously different depending on the graphics card / video card you use. Even when the WindLight settings are 100% the same.

How to proof this?

Comparison shots of the same locating taken with - fixed - noon, evening, midnight and dawn settings with different graphic cards.

Needed

  • An object that makes sure that if an avatar stands on it, the object takes over camera controls so everybody shoots exactly the same scene. (I think I once saw Arahan Claveau use this?)
  • XML settings for noon, evening, midnight and dawn.
  • Residents willing to take those 4 shots and list their type of graphics card. You can upload them on Flickr or e-mail them to me. Let’s say we’ll shoot at 1600×1200px? And, guys and gals, no Photoshopping allowed! ;)

Who will help?

XML Files

Chinese volunteer for helping Vint with the XML WindLight files: Kailie Quinn (Katarina Malthus) (Vint can host them if needed?)

Fixed-view Object

I’m game to be volunteered. My card is a 7900GS. There is one itty bitty problem with this whole test. I have a color calibration device, from GretagMacbeth, but I suspect most other people do not. Which is going to make each image appear differently on each person’s monitor by being uncalibrated.

Another thing that might throw bits off is driver version….

(Why do I have one - it’s for photography - it is actually important to have your monitor calibrated if you are going to do any modicum of serious work with a real image.)

dandellion Kimban wrote a comment on November 23, 2007

Vint Falken wrote a comment on November 23, 2007
MyAvatars 0.2

Quick answer to Veryon, I’ll complete the volunteer list ASAP (yey! thank you!):

V., let’s imagine we shoot your pretty pixelated butt, then calibration does not matter that much (in this case), because it’s a comparison. If the monitor’s calibration is ‘off’ from what you could consider standard, then all pictures viewed on that monitor will be the same amount of ‘off’. So comparison still stands?

I for instance know my monitor is set a bit to dark (losing shaded tones, having more details in the white keys), but else my eyes don’t last for two hours. :)

ps. Google does not have any kind of free - software - calibration tool? ;)

And Tiessa: yay! you’re still alive.
Dandellion: yay! you still read my blog. =d

Thanx for the email, Vint. Incidentally, this is the first time I’ve heard the term, “Chinese volunteer”. :)

I’ve forwarded this to the whole WindLight Team to ask for further insights. It occurs to me that in some cases, “differences” might be not by design and due to bugs, and in other cases, Preferences settings may be varied too — so I would at least suggest making sure those are consistent. Furthermore, there are a number of finer graphics settings which can be found in NVIDIA and ATI driver control panels (like antialiasing) which do make a visual difference…

I think it’s pretty cool you’re doing this initiative, and not to complicate things *too* much, but additional points to consider! =^_^=

Vint Falken wrote a comment on November 26, 2007
MyAvatars 0.2

You never heard of Chinese Volunteers?!! Maybe it’s a Flemish or Dutch terminology, I’m not sure… Chinese Volunteers are volunteers appointed by the government or whomever is running the place. Most frequent Chinese Volunteer jobs: playing ’secretary’ at a meeting, cleaning the toilets on a scouts camp, etc. =d

The preferences should be consistent by using the XML files for Windlight settings and buy advising graphic preferences settings. (If a certain card can not pull those, it’s inherent to the video card and thus relative to the comparison.)

You are right about the card’s own preferences though, I must admit I did not consider those. :( But I mainly want to have an idea how others ’see’ WindLight, so using their defaults will be ok? It’s somewhat like how our humans see the world. We can describe it, but can never be sure that what I call red is what you call red. For instance, I see detail in black where my mother just sees black. (I assume our brains calibrated the eyes differently? =)

I’ve got my fixed camera chair, so I’m ready to set up the XML files & the inworld location. I think. :p *goes to read her checklist again*

Driver settings can make a big difference Vint. After installing a new driver for my graphics card a while ago the jagged edges I got were horrible untill I turned antialiasing on in the driver settings. Seems most games do that themselves … not so SL, it leaves it up to the card’s settings.

@Vint: Being a “Chinese volunteer” doesn’t sound too prestigious haha, but that’s okay, I’ll do my grunt work! ;) (I’m also going to look up the term and learn more…)

And, wanted to let you know WindLight Team gives our big smile to this and they’re eager to see how quickly + effectively it can happen. Resident-run collaboration excites us (and me personally) so much. I’ll of course gladly participate once things get rolling.

We had an internal meeting where we brought this WindLight Comparison Project up, and: minor variances across GPUs are to be affected due to all the many visual settings involved, but if there’s *significant* differences (I believe Steve Linden used the analogy of a “red” apple on one screen looking “blue” on another ;) ), then those are likely bugs which we need to fix… and hopefully these tests can help us uncover them.

On a related note, I’ve also started this:

Torley, eager to see how quickly + effectively it can happen. So am I. You guys have Lindens that could code an automated submission system for the photographs. I do not. I don’t even own a sweatshop to let others do it. *sobs*

As for the settings, yes, of course there will be minor differences, but I’m not hunting for bugs. I’m just ‘darned’ curious about how others see what I now think of as my world. PS. I know of blue eggs and blue ketchup? :D

Is anything happening with this?

I’d be happy to help too, if you’re still looking for more volunteers. I am currently on a laptop with a GeForce 8400M GS, with ForceWare driver version 101.28, and all the nVidia settings left at the defaults (or at least, I haven’t changed them anyway).

A bit confused about why you need XML files for noon, evening, etc though… Couldn’t we just use the defaults? Or would the files be for the WindLight graphics settings in preferences too?

On another note, everything got a lot more jagged for me too back when they implemented the rendering pipeline changes a while ago. No idea if it’s still that way now or not though, as I’m on a different computer and graphics card now anyway, and it was ages ago so I can’t remember what it looked like before :)

Care to comment?
