That's extraordinary, Bjorn.

Earlier today I updated the second version of my normal map (link above), to smooth over a few spots where there are glitches in the source data.

Finally figured out self shadowing terrain that I've been struggling with for a while... a couple of what I THINK are realistic renders, plus one with UBER-EXAGER-TERRAIN and a final one that's exagerated, but only to look a bit more realistic. It seems I have to turn up above and beyond what I'd expect the numbers to require for realistic terrain - perhaps because of the comparatively low level of detail in the terrain models.

And because the resolution isn't that good - a bit of foreshortening to get a look at Eddington for Stu

These Kaguya-derived images are absolutely stunning, great work everyone. This actually feels like a planetary encounter, with new images of a new world for us all to drool over...

And thanks for the Eddington pic Doug, much appreciated. I've some big talks coming up before Christmas and really want to be able to show off that crater, for obvious reasons :-)

I like the exaggerated one. Somehow on a globe it doesn't seem to be terribly out of place. I think it's useful for understanding the terrain and relative elevations and crater depths.

If Occam had heard my theory, things would be very different now.

I wonder when we'll see the first program that accurately renders this topographical data so we can really plan our lunar observations...

Excellent renders, everyone!

For those of you wondering, as I was, which one is Eddington Crater...

I had to look it up as well smile.gif And S_Walker - the answer is about 2hrs, 40 minutes. The post following yours qualifies I think.

Thanks. What about those who don't own an iPhone?

Nah... Google Moon is nice but it doesn't use a topographic map for lighting as far as I remember? And I'm not sure if you can set it to show the view from your backyard.

Can Celestia be set to view the Moon from a position on Earth? At least two of us have already produced normal maps; it's a small step from that to the amazing screenshots that volcanopele was posting.

I imagine what S_Walker really wants is something that does Bjorn- or Doug- type rendering to show the Moon from a location and time on Earth. Don't know about that. But Celestia or Moon Globe would probably be good enough for a lot of purposes.

Similar; I'd like something like Virtual Moon Atlas or RITI Lunar Map Pro so that I can better plot interesting features to observe under favorable librations each month in Chuck Wood's Explore the Moon column in S&T (I edit it each month).

I see. Well as Doug points out, Moon Globe may well be first out the door with those features, for anyone who has an iPhone or iPod Touch. And it's free. I'll be submitting the update using LALT data quite soon. (End promotion.)

I don't own it, but RITI Lunar Map Pro looks like they definitely *should* upgrade to the LALT data for lighting. (Adding: Ironically, the LALT data is actually less sharp than the airbrushed topographic map they seem to be using - I know that because I was using it too. So they may have a problem with that. But even though it's low resolution, the global LALT map we've seen is vastly more accurate.)

Virtual Moon Atlas looks like it doesn't do topopgraphic lighting, so that would be more of a reach.

Celestia can do this, but the UI for doing so isn't as convenient as one would like. The Celestia UI was designed around moving through space, and features for viewing from the Earth's surface have never gotten the attention that they deserve. But, see question #5 here:

http://shatters.net/forum/viewtopic.php?p=118149#p118149

We're in the process of making the Kaguya map the default in Celestia, and a UI overall is coming in the not-too-distant future.

(I've got an iPhone and love the Moon and Mars globe apps, btw. Great work!)
