Re: Textures on models

Krisci,if you copy the 3ds files into the same folder as the textures and then import to 3ds Max it should then load the texture links into Max.To get them to show on the model,you need to use the Material editor to instance all the materials (in the editor) and then click the button for each textur...

OK,mate here's a shot from close to the rings

I think the ring particles may only be included in the hires version as it runs pretty slow on my PC.Jestr

Re: Planet Rings

Hi Andrew,as part of my Stargate-Bane addon on the Motherlode,I have made a gas giant planet called Repsilon,which has a ring system which has thousands of little ice rocks making up the rings,it wouldnt match exactly with Saturn though as the rings are a little different to Saturn's.You can downloa...

Re: Comet Tempel I shape model

I have been trying this shape model out in Celestia,but I can't get it oriented correctly for the impact,because I think we need more accurate orbit data-specifically RotationPeriod and RotationOffset-any ideas (Grant?)
Cheers,Jestr

Re: SPICE

Great news Chris,How does it work in practise.looking at the bsp files for Cassini,for example.Do we need all of the bsp files for each time period (and specify a start and end time,for each, for Cassini in the ssc file),or can they be stitched together into one file?Jestr

Re: Eros

If you were to make 3ds versions out of these models,they would need to be chopped up into many pieces.As far as I know the limit for a 3ds object is 65535 faces,whereas the 1440 mesh has over 2000000 faces and the 720 mesh has nearly 517000 faces.Splitting them up will mean many nasty seams unless ...

Re: How up to date is Cassini's trajectory in Celestia?

PS. Jestr, I just followed Huygens trajectory down to Titan in your new addon, and I really enjoyed it. Excellent attention to detail with all the transitions, deployment of parachutes etc!! You should consider writing a script to best show it off to newbies who may not know how to track it, etc. C...

Re: How up to date is Cassini's trajectory in Celestia?

Actually,I tend to agree with bdm,the problem is a rendering one,the positions of Cassini,Mimas and Saturn all look reasonably accurate to me (though of course,I'm no expert).I just think there isn't enough light reflected off Mimas,but we've had this discussion many times on the forum,and our monit...

Re: How up to date is Cassini's trajectory in Celestia?

Hi Chuft,only eight of the nine planets use VSOP87 (not Pluto),most of the moons have their own hard coded Customorbits,but I dont know how these are worked out.Jestr

Re: How up to date is Cassini's trajectory in Celestia?

The xyz file I made for the addon linked to above is called jestr_cassinigrandtour0505.xyz If I remember correctly,Runar updated this file for me on the Motherlode. If you have this file already and Cassini still flies through Titan,let me know when this happens and I will correct it,I'm pretty sure...

Re: How up to date is Cassini's trajectory in Celestia?

Hello again Chuft.The position of Cassini looks to be about right though,dont forget that the position of the moons themselves may be slightly out,Mimas has a customorbit definition,but I remember when I was compiling the Cassini xyz orbits and checking it against the planned flybys,several times I ...

Re: How up to date is Cassini's trajectory in Celestia?

Hi Chuft,I don't know of any recent changes in the orbit of Cassini.I have just looked on the JPL Horizons computer and the latest ephemeris they have are from March 23rd 2005,I updated the xyz orbit for Cassini using these ephemeris in May 2005,and this is available on the Motherlode in this addon ...

Hi Selden,this isnt the case when opened in Photoshop.In Photoshop it only shows the sea parts in layer0,and has no alpha channel.Obviously it opens OK in other image software.Jestr

hi stargate,there used to be a lot of star trek models,on a site called startrekaustralia,but I cant seem to find it now,there is scifi3d also,and another site called http://www.trekmeshes.ch which have a daedalus class model,but it looks quite simple,hope this helps,Jestr

OK Hungry,I think the answer lies in adapting the XYZ Builder.celx file (you can open it with notepad or wordpad) and change the line gHELIOFRAME = celestia:newframe("Planetographic", celestia:find("Sol"), 2451545.0) entering the name of your fictional star "Kalad...
