Re: .CEL "Planetarium Mode" Statements

Yes, Selden. You are correct. I specifically asked about .CEL scripting - NOT LUA scripting. Thank you! And you answered my question - these "planetarium mode" related functions do not currently exist in Celestia. It would be nice to see them implemented in Celestia version 1.7.0. They see...

.CEL "Planetarium Mode" Statements

Hello, Am I correct in my understanding that there are no .CEL statements equivalent to any, or all, the following three interactive functions (for the purpose of scripting a "planetarium mode"): 1) GoTo ground. 2) Set Alt-Azimuth mode. 3) Point camera to a specified azimuth (and possibly ...

Re: Celestia 1.6.1 Windows Install Files

Re: Celestia 1.6.1 Windows Install Files

Thank you, John.

But are all the Celestia 1.61 for Windows 64-bit (Original Shatters.net; Celstia.space; and Sourceforge) the same? If not, how do they differ?

Thanks!

Celestia 1.6.1 Windows Install Files

Hello, I have a basic question. I've been away from Celestia for a few years, but plan on installing it on my new Notebook. I still have the original Celestia 1.6.1 Windows install file from the old Shatters.net site. Is there any difference between that install file, and the one found here on Celes...

Planetographic Grid lines do not show for Titan

When "Reference Marks" > "Show Planetographic Grids" for Saturn's Titan are enabled, the grid lines do not appear. The latitude and longitude values appear, but the grid lines themselves do not. At first I thought Titan's light surface color background was the problem, but the sa...

Thanks jogad, but I already know that. I'm looking for the CEL script "set AmbientLightLevel" equivalent values for "Low" and "Medium." Thanks!

Re: SSC Location File Coding

Thanks bdfd and John. That's exactly what I was looking for! The only thing not explained is why the directive "Importance" is expressed as a two-decimal place value in all of the examples I've seen (such as "150.71"). Is it just to provide increased granularity? Or is there some...

SSC Location File Coding

I apologize in advance for asking a question about something that, I am sure, must be documented somewhere - but I just spent a couple of hours searching documents and this forum, and I'll be darned if I can find it anywhere! I would like to find the documentation for coding the SSC Location File pa...

Re: Show a line indicating geographic position

Keep in mind, however, that the Earth is not a sphere, but is a somewhat flattened oblate spheroid - and that geographic latitude, as is used in celestial navigation, is not measured as the central angle at the Earth's center. It is measured from the line that is normal to the Earth's surface at the...

What "set AmbientLightLevel" values are equivalent to the manual "Low" and "Medium" ambient light levels? Obviously the value of 0.0 is equivalent to "None." Thanks...

What does the "partialtrajectories" parameter of the CEL "renderflags" statement do? I can't seem to find it anywhere. Thanks.
