ATR-42 04-15-08 03:01 PM

Some of these were taking at work while flying, the others were taken at sea, about 100 east of NJ while fishing.

Also note, the seas, for those that say the ocean cant be smooth as glass heres proof ;) these shots were taken from the deep Atlantic canyons (6000+ feet deep)

They arent the nicest or prettiest pictures, but they give a good idea as to the "size" of the sun...

Wow, nice!

i like the moon and sun smaller

on a side note, can anyone help me with this problem?
after noticing this i upgraded to the latest drivers and it didn't help. i have TMO, RSRD, and PE, but it happens no matter what mods i have installed:
Radeon HD 2600 PRO

That's a stock scene.dat issue, if memory serves. Happened with the ATi 2xxx series. Should have been eliminated in the scene.dat PE uses :hmm:

The sun and moon do NOT get bigger, it is just an illusion due to proximity of scale objects they lack higher in the sky.



I realize they do not actually get bigger, that is why I used the term "appear to get bigger". The point being, when the sun hits the horizon (on the water) it takes only minutes to disappear. You can witness movement. As someone stated earlier, "I timed it and it took seven minutes". It's certainly not a big issue, just an observation.

ATR-42 04-16-08 10:22 AM

in game it seems to take between 10 and 15 minutes to fully set... i think?
the rate isnt much of an issue, heck gives us a few more seconds to enjoy krillers work, but the physical size of the sun i think should be looked at...

the current size is dramatic, which i embrace its coolness, it is after all a sim ;)

Just

Soundman 04-16-08 12:08 PM

Well, I screwed that up ! I was trying to post a pic here. To make my point about how sometimes the setting sun can look huge, check out this pic. I saw many a sunset like this when I lived in Key West. Sorry about the goof, how do you put a pic in here anyway? I could not find an answer through the forum search, but here is a link.

There's no "should" to it, that's exactly what they do!

There is some effect from atmospheric refraction that makes this period difficult to exactly judge if you want to actually time it with a stopwatch. Basically it smears the image horizontally along the horizon. I haven't checked to see if this is reproduced in the game.

I tend to believe at times there must be some type of effect or refraction going on. See the how big the sun is using the link in my post above for a perfect example of what I'm speaking of.

tater 04-16-08 04:58 PM

There is refraction, 35 minutes of arc. It is pretty much equal though, so this simply delays sunset by ~1 diameter.

I said SHOULD because it should in the sim (but doesn't) ;) Not because I think it should in RL.

PE didn't fix it, neither did any other environmental mod... :(

any way you can tell me what i need to do to fix this? mebbe i'll just make my own thread

Good idea... That way this thread can stay on topic...:up:

Carotio 04-17-08 07:06 AM

I think it's the same as for the moon. Once they're close to the horisont they appear larger than when they're high up in the sky.

Anyway, as I see the poll so far, it seems that a single seperate download would seem the most popular, so I'll pack it later and release it...

DeepIron 04-17-08 08:40 AM

The "apparent" increase in the size of the moon and sun near the horizon is caused by and atmospheric "lensing" effect. It makes them look "bigger" than they actually are. I think this would be hard to simulate in the SH4 engine...

tater 04-17-08 08:56 AM

With all due respect, deepiron, that is not true. There is no lensing effect that makes them bigger. As measured, they simply do not appreciably increase or decrease in size at the horizon. Any "lensing" would none the less be measurable... caliper the moon or sun, and compare to zenith. This is entirely psychological. It is because when the sun or moon is at the horizon you can compare it to the objects also on the horizon. In the case of the sun, you can actually look right at it, which in itself is an issue since you really cannot dwell on the size at zenith.

The refraction that does occur bends the path of the light such that the sun/moon appear above the horizon longer, and the setting is actually a couple minutes after they are under the horizon. It doesn't grossly change the geometry. At low altitudes in particular, you can see some distortion, but the size is largely unchanged (perhaps measurable, but were talking arc seconds here, not, "wow, that's HUGE!"). The distortion is actually a flattening in the vertical due to the atmosphere acting as a prism. So in one dimension it is actually smaller, not larger.

ATR, that image looks big because it's taken with a telephoto lens (or cropped), no more.

The sun and moon are not bigger at the horizon, period.

In fact, they are farther away at sun/moon rise or set by one earth radius.

I think it's a question of how do you see the sun when looking at sunsets? and most people would say it seems bigger incuding me, so that's what I am aiming for in PE 2.1 , are the sun on this picure to big ? (It's resized to 1/3 of PE2 and 1/2 of stock SH4)

DeepIron 04-17-08 09:12 AM

Absolutely true.... I stand corrected... I was mistakenly thinking of the "mirage" effect http://www.islandnet.com/~see/weathe...ts/supmrge.htm which I've seen numerous times in Alaska, especially in very cold winters, and mostly across large bodies of water. It both shifts and increases the apparent size of the observed object...:oops:
