[Celestia-developers] New cel functions

[Christophe T. <ch...@te...>]

Welcome back Chris, I hope you had a great time in New Zealand.

The attached patch adds a cel script function and overloads four existing 
functions.

Is it ok to commit before 1.3.1? Are we nearing 1.3.1?

New function: 
** seturl 
Arg: url (string)
Takes you to the location of the cel:// url.
Example:
seturl { url 
"cel://Follow/Sol/2002-09-01T16:58:51.32378?x=AAAAAMCrktOdILb5/////w&y=CkxgAADEXts7E7HX/////w&z=VcpQAAAAAAAAAMIy/////w&ow=0.090610&ox=-0.494683&oy=0.860207&oz=-0.084397&select=Sol&fov=49.499992&ts=1.000000&ltd=0&rf=6043&lm=0"} 

Overloaded functions:
** time
Arg: utc (string)
Sets the time according to the UTC date string in YYYY-MM-DDTHH:MM:SS.SSSSS 
format.
Example:
time { utc "2002-09-01T16:58:51.32378" }

** setposition
Arg: x, y, z (string)
Sets the observer's position to the x, y, z coordinates encoded in Base64.
Example:
setposition { 
       x "AAAAAMCrktOdILb5/////w" 
       y "CkxgAADEXts7E7HX/////w" 
       z "VcpQAAAAAAAAAMIy/////w" 
}

** setorientation
Arg: ow, ox, oy, oz (number)
Sets the observer's orientation to (ow, ox, oy, oz).
Example:
setorientation { 
       ow 0.090610 
       ox -0.494683 
       oy 0.860207 
       oz -0.084397 
}

** gotoloc
Arg: time (number), x, y, z (string), ow, ox, oy, oz (number)
Travels to the coodinates (x, y, z) encoded in Base64 and sets the orientation 
to (ow, ox, oy, oz) over time seconds.
Example:
gotoloc { 
       time 2 
       x "AAAAAMCrktOdILb5/////w" 
       y "CkxgAADEXts7E7HX/////w" 
       z "VcpQAAAAAAAAAMIy/////w" 
       ow 0.090610 
       ox -0.494683 
       oy 0.860207 
       oz -0.084397 
}
