Ok, I see that I can specify CloudNormalMap command in the ssc file but, still not sure about SRTM and Bathymetry. Any help here would be appreciated.

Hi All Is it possible to use more than one Normal Map on a given model. For example i would like to see what earth looks like with the SRTM data, the Gebco Bathymetry data and a normal map i created with the photoshop dds plugin for some clouds. But i would like to see them all at once instead of cr...

Thank you Gentleman!

It's amazing how 1 pixel can make such a huge difference!

Hi all I just downloaded the Earth Bathymetry map found here: http://snowy.arsc.alaska.edu/nasa/topography/gebco_bathy.21601x10801.bin.gz I followed step by step the directions according to this post using Fridgers code: http://www.shatters.net/forum/viewtopic.php?t=10071&start=15 And this is th...

Thanks again Spaceman Spiff. A very clever fix. Here are a couple before and after shots.

Hi Fridger The home of my nmtools package is our CelestialMatters site (click on the CM icon below). There you also find my detailed step-by-step tutorial. The nmtools are made for people to obtain huge scientific grade normalmaps with normal home computers. Hence the input is for 16 bit binary elev...

I've searched the forum and haven't found an answer to my question. Do the nmtools ONLY work for binary height maps or will they work with say, Bump Maps, or Embossed images? I know they do not work for RGB images but so far I have only been able to use them with the SRTM .bin files for Earth. :? :?

fsgregs, Post Posted: Tue Aug 07, 2007 9:23 am Post subject: Ozark: WOW, I've never run across a 3 Gigabyte single image file before. It's a bit too large for use in Celestia Wink . Does anyone have a more user friendly night texture that is recent? The ones on the motherlode are good, but I'm just ...

Thanks for the tip Spaceman Spiff, I'll give it a try. BTW you are quite right about the night lights!

Does anyone out there Know of maybe a bash script or an exe program to resize an image while retaining image proportions? For example I'm coming across a lot of files that are saved in different sizes such as 43201x15601 but when converting them to say, 32768x16384 the image proportions turn out mor...

Nip2 worked Great! Didn't Know anything about nip2 so i didn't try it. I've since started playing around with it more and getting to know the program a bit more. Anyway, vt'd both 16k version and 32k version. You guys were right 16k version was better. I kinda of figured that but wanted to try for m...

Hi fsgregs,

It's not Johns Map but its about as real as you can get!

For a realistic view from Earth as far as "color" goes, google sattelite images, and then color the maps accordingly.

I am fairly new to the Celestia forums, I have asked my share of "newbie" questions and may ask more in the future. But I love the challenge of figuring out on my own how to use all the features Celestia has to offer. I am no programmer am not familiar with anything non-windows (sorry Fridger, I kno...

I haven't tried nip2 yet. Ill try that before i scale it down and see what the results are. Actually i planned on making a 32k map as well as 16k so i could see for myself the differences. Thanks

I downloaded a mars jpeg image with 23040x11520 dimensions and resized it to 32768x16384 tif. But i do not know how to convert it to Png or Jpg to vt it. I've tried imagemagick, irfanview, Photoshop, vips, but none seem to be capable. :( when i resized it in Photoshop, i was only able to save it as ...

:D :D :D Success!! Thank you john! :D The problem i was having (and perhaps i wasn't doing it correctly )but whereyou said: cd C:\\Path to test and hit enter then type sh vipsvt.sh *.png 512 png and hit enter and see what happens for some reason typing vipsvt.sh was causing my problems. When i typed...
