Mars Like Planet

Well, the only thing I really don't like about this one is the polar cap. It just doesn't seem natural, too white (or perhaps, too sharp). I'll keep working on it and probably come up with some kind if scene composition. C & C welcome.

Wow.

If I were you, I'd put a copyright on your images. <-- Me being serious.

I like the ice cap actually. Looks more realistic than the real Martian ice caps

amazingly WOW!!

Nice job, all i would add is some craters, possible? and some huge canyons and peaks. A low density mirky white cloud layer for sand storms. Overall it looks great.

Sethern, could you even see all of that from this "distance"? I'm not sure how high up we're supposed to be, but my greatest challenge with these shots is how much would actually be visible.

This is as about as realistic as I've seen, which begs what I know. Never been at this distance before. So...

Yep, I'm already planning on trying to add just those things after I finish a current render. And calico, check out this image I'm using as a reference. http://www.windows.ucar.edu/mars/images/mars1.gif If I could, I would like to get something like this.

Pretty flippin' close.

There's very little impression of atmosphere here in terms of its effect on the perception of terrain details. I know a Mars-like planet would not have much atmosphere anyway, but things do seem a bit too sharp and clear, especially around the polar cap, but also in many of the other rough areas of the planet. I'm not sure whether softening the actual texturing, or just increasing atmosphere would be the preferable approach. Otherwise it looks very good though.

Btw your Mars reference image has a lot of artificial noise due to dithering because it's in a 256 color GIF format. This is probably a better reference: http://www.urania.be/sterrenkunde/images/mars-groot.jpg Notice how there are a few sharp details, but for the most part everything is a bit softer. And this is what Hubble sees: http://www.esa.int/images/2003_hubble_mars_l.jpg
Another good one: http://wanderingspace.net/wp-content/uploads/2007/03/mars-portrait.jpg
Note the subtle effect of the atmosphere here: http://www.astro.uio.no/ita/nyheter/rosetta_0204/images/MarsNACTwoColor_H,0.JPG
And finally, the real polar cap: http://wanderingspace.net/wp-content/uploads/2007/08/mars-polar.jpg (Matt is right

Nice mate, I agree with what Oshyan said above.

zionner · December 19, 2007, 03:47:28 PM

Nice!

I love the details in this planet (Whether others think otherwise or not.)

I wish i could do planets like this, but I dont understand Image Mapping well:/

rcallicotte · December 19, 2007, 03:54:36 PM

I don't think this was image mapping. Was it?

Ah..lol

nvseal · December 19, 2007, 04:30:46 PM

Nope, no image mapping.

And Oshyan, yes, I have some of those images. I will admit that I'm taking some liberty away from the real thing but hey, I'm not done yet.

Although it's not image mapping, and it's looking great, here are high res 5.7k textures of Mars which could be useful for reference, including an elevation map: http://www.buining.com/
