Celestia Forums

although not fully realistic i think i can make ya a good texture, want it to look like a giant diamond, or a blue tinted rocky terrestrial? Apologies for the late reply. I wasn't expecting to get an offer to make a texture after this long since I first uploaded this addon. Nevertheless, I am very ...

For those who have been trying to download the addon and couldn't because of the broken link, the link has been updated and should work now.

Best,

I'm using one of Alexell's x64 1.7.0 builds modified by Janus to use QT 5.6.3 & VS2013.

cartrite , I've found that there are two primary ways to make a model with intrinsically-defined textures and/or normal maps work in Celestia. Either you must tell it to use the model in its initial definition (for Mars this would be in the solarsys.ssc file) or to write a new definition in a diffe...

I sent him a link to a more detailed model of Spitzer some time ago; perhaps he could work with that.

So it appears you have a good idea of the steps that must be taken to produce this high-definition model of Mars. While you work on rewriting your script, I'll try subdividing the plane many more times in Blender to see if I can get it to be displaced properly. Also, thank you for the help you've gi...

Unfortunately, not all the topics are archived; I tried to go to two different topics, and neither are saved.

I attempted to process the mars heightmap using the script and the instructions you linked to above, however two problems arise: 1. The "Noise" button doesn't displace the mesh. 2. The script errors with the following message: Traceback (most recent call last): File "<string>", l...

So this is a script written for an older Blender version. Can this be used to transform a heightmap into a spherical mesh? What Blender version does this work for?

I am not very good with Blender, so I don't know how to put this script into action, if that's your plan.

What build environment are you using? I was using MINGW64. Attempting to compile with tools enabled caused a multitude of errors that I don't quite remember. I am attempting to run cmodsphere on a txt file of the mars file. I found that isis2ascii was needed? So far I have not succeeded. I have the...

So, should I first reduce the size of the .cub heightmap to 32k using the reduce program before cropping it? Or is the cropping supposed to precede the reduction in size? Based on your instructions, I am assuming the former is the case. So I'll need four crops, one from sample 1 to 16384 and line 1 ...

I wouldn't recommend getting that file. I would use the ISIS cub. Out of curiosity, why? What is the difference between the .tif file and the ISIS .cub file, apart from the apparent 180-degree offset? Also, after searching, I found that the program in question was indeed cmodsphere. I am attempting...

cartrite wrote:There is also a program that I think is part of Celestia that will change a topo map into a cmod. Chris Laurel wrote it along with Fridger Schemp. I think it's part of the tools folder.

What is this program called, and do you happen to have a build of it available?

Is this situation made any less difficult by the fact that I found a large Mars height map (46080x23040 px) on the USGS website?

Ok, so I successfully got a Ubuntu VM working on my laptop, and was able to install ISIS3 via Anaconda in the VM. I downloaded the base data (including the molaMarsPlanetaryRadius0005.cub file) and installed GDAL (also in the VM) in order to work with the .cub file. Now, what do I need to do? What c...

When I get the .cub file, what do I do with it? How to I get from the .cub file to a usable model that can be textured?

Thanks! I apologize, because upon reading your post more, you did use the model and texture from this thread, so your post is more relevant than I thought.

This was my 1st year on here ever and I wanted to discuss those who were interested in such topic and many were wondering how the star Stephenson 2-18 would be rendered and I did my best to render it with the best coordinates and magnitude. If you wanted to do that, you could've made a new topic in...
