Celestia Forums

Very nice! How did you convert it? What was the source version? I used the 2019 NASA version, but it is very hard to convert.

The 3ds format is basically dead. In my opinion the obj format is useable, but we need either a direct Collada support in Celestia or a perfect obj/dae to cmod converter utility. Currently the obj->cmod conversion is not very good, the end result textures are very different from the original ones. Y...

You can use MeshLab to convert to 3ds format. Obj format can be imported into cmodview, but it is not perfect:

Celestia should use the COLLADA dae format.

Png and jpg textures caused constant crashes on Celestia 1.6.1, so I had to convert them into dds. The crashes disappeared. Now I mostly use 8192x8192 pixels dds tiles and it is flawless. But then again I have a PC and I use Win64 + Celestia 1.6.2 with 40GBs of add-ons.

Every video card likes DDS textures. It loads way faster.

I think we should collect 3D models links relevant to Celestia. First links: https://3d-asteroids.space/ https://solarsystem.nasa.gov/resources/2377/asteroid-itokawa-3d-model/ https://www.eso.org/public/products/models3d/oumuamua/ https://nasa3d.arc.nasa.gov/models

It is based on a NASA map. I think they are bigger, mainly "optical" concentrations of bright stars.

I cannot use the tool, because I don't understand the math. Someone should explain it with this data set and with this problem...

I know this is the problem: https://en.wikipedia.org/wiki/Axis%E2%80%93angle_representation

Method number 2: 1.) Convert the mesh into .obj format 2.) Open the .obj format with cmodview 3.) Save the opened mesh using the cmod format 4.) Open the cmod mesh with the 3ds to cmod convert and fix utility and use the "Fix" function with the "Output as Ascii" option to create ...

Steps: 1.) find the object's model and download it (if it's legally possible). It can be virtually any type of 3d mesh 2.) if Blender can import it, then import it into Blender 3.) use MeshLab to open the 3D mesh if Blender can't import it and save it as an .obj mesh 4.) import it into Blender and u...

This data (Axis [-0.679381 0.221716 -0.699488] Angle 196.475) places the mesh in the target galaxy (Milky Way), but the mesh has a wrong orientation. So the end result is perpendicular to the Milky Way plane. I want to rotate the mesh 90 degrees to be on the plane of the Milky Way. This is the mesh ...

Help!

How can I rotate a dsc nebula mesh a "normal" 90 degrees?

This data -> Axis [-0.679381 0.221716 -0.699488] Angle 196.475 is perpendicular.

It is very easy to make, I will make a tutorial.
