I want to change Project Parameters like 'FogColor' , 'DisplaySun' , 'DisplayMoon' etc.
I am using the following commands in SGAPI :
 
1. ITerraExplorer51.set_ProjectParam("DisplaySun",true);
 
2. ITerraExplorer51.ProjectParam("DisplaySun")=true;
 
3. teCoClass = new TerraExplorerClass();
terraExplorer = teCoClass as ITerraExplorer51;
terraExplorer.set_ProjectParam("DisplaySun", true);
 
After implementing the above codes i am unable to get any result.
Similarly using "FogColor"  option i am unable to change the Fog color.
 
Please explain how it works??
and will "DisplaySun" show a virtual sun or not? just like a virtual moon which is visible in TerraExplorer Pro. 
and how can we change the location of this virtual moon/sun wrt any location on globe??

Hi,
The following SGAPI code turns the sun off  and set's the fog color to green:
 


<html>
    <head>
        <title>Project param test</title>
        <script src="http://www.skylineglobe.com/SGAPI/v2.0/sgapi.js"></script>
        <script language="jscript">
        
        var globe = null;
        
        function Init()
        {
             globe = new SGWorld();


  ITE51 = globe.innerTEObj.Interface("ITerraExplorer51");
  ITE51.ProjectParam("DisplaySun")= false;//Turn sun display off
  ITE51.ProjectParam("FogColor")= 65280;//Set fog color to decimal value of green (0xFF00)
        }
        
        </script>
    </head>
    <body onload="Init();">
    </body>
</html>
 
The sun is positioned in the sky based on the current TerraExplorer Time.
You can see more information in the programmer's guide chapters for IDateTime5 interface. Changing the time, will change the sun to the correct position in the sky based on the paramters.
 
Hope this helps...
Eylon
