Celestia Forums

OK, here's my first novice attempt at contributing to this fantastic project, 3D add-ons for galaxies M83 and NGC4314. They can be downloaded from:

http://celestiamotherlode.net/creators/davemc/M83.zip

http://celestiamotherlode.net/creators/davemc/NGC4314.zip

The directory structure should be preserved within the Zip file so if you extract it to the Celestia\extras folder everything should be set up correctly.

I must give credit where credit is due. The 3D models used were created by (I think) by AstroBoy and Selden for some of their add-ons. I only did some very minor tweaking using Anim8or for these.

I'd appreciate any feedback - good, bad, or ugly.

Thanks!
Dave

Dave,

The pictures and models look great!
There's a problem with the DSC file for M83, though: it isn't oriented correctly when seen from the Earth.

Link to SEDS Web page for M83:

As provided in your Addon:



With adjusted Axis and Angle so it almost matches the SEDS picture:



Generating more accurate values would take more time than I have right now and is left as an exercise for the artist

Hi Selden,

Thanks for the info! I'll add your M83 orientation values and then fine tune it as soon as I can.

Dave

Both add-ons should now have the correct (OK, at least close) orientations.
