[1.187.209] raycasts detect planet when raycasting away from it over larger distances

Hello when playing around with the Mod and Ingame Programming API I tested a bit with the IMyCameraBlock.Raycast(double, float, float) Method.

I will demonstrate the issue with ingame Scripting (I know its experimental but its able to show it pretty easily).

I built a camera on my ship as well as a Programmable block and enabled the Raycasting function. And I looked in a random direction. (See Screenshot: 20180930154458_1.jpg)

When I perform a Raycast of 10km I get the information that Nothing was Detected as I expected. (See Screenshot: 20180930155338_1.jpg)

But if I do a raycast of 100km I get the information that I hit planet earth exactly 100km away from me. (See Screenshot: 20180930155440_1.jpg)

This is not what I was expecting since there is still nothing, so there should not be any planet detected. Especially not at a hit position far away from the planet itself.

However I assume this has something to do with performance, but It should be possible to determine if I am actually scanning towards a planet or away from it to reduce wrong data reports.

To verify this bug here is the test-script I created:

IMyCameraBlock camera = null;  
 
Program() { 
    init(); 
} 
 
void init() { 
     
    camera = GridTerminalSystem.GetBlockWithName("Camera") as IMyCameraBlock;     
      
    if(camera != null)  
        camera.EnableRaycast = true;  
} 
 
void Main(string argument) { 
 
    if(camera == null) 
        init(); 
 
    if(camera == null) { 
 
        Echo("Camera not found!");   
        	Me.CustomName = "GPS:Target:NA";     
 
        return; 
    } 
 
    float maxDistance = 10000f; 
 
    if(argument != null && argument.Length > 0) { 
 
        if(argument.Equals("update")) { 
            printScanRange(camera); 
            return; 
        } 
          
        if (!float.TryParse(argument, out maxDistance))    
            maxDistance = 10000f;    
    } 
 
    if(camera.CanScan(maxDistance)) { 
 
        MyDetectedEntityInfo info = camera.Raycast(maxDistance, 0,0);       
         
        MyDetectedEntityType type = info.Type;  
        if(type != MyDetectedEntityType.None) {  
 
            Vector3D offsetTarget = (Vector3D) info.HitPosition;  
 
            Echo("Target: "+VectorToString(offsetTarget, 4, ", ")); 
            Echo("Center: "+VectorToString(info.BoundingBox.Center, 4, ", ")); 
            Echo("Name: "+info.Name);             
            Echo("Relationship: "+info.Relationship); 
            Echo("Velocity: "+info.Velocity); 
  
            	Me.CustomName = "GPS:Target:"+VectorToString(offsetTarget, 4, ":")+":";     
 
            printScanRange(camera); 
 
        } else { 
             
            Echo("Nothing found!");  
            printScanRange(camera); 
            	Me.CustomName = "GPS:Target:NA";     
        } 
 
    } else { 
 
        Echo("Scan not Possible!"); 
        printScanRange(camera); 
        	Me.CustomName = "GPS:Target:NA";     
    } 
}  
 
void printScanRange(IMyCameraBlock camera) { 
    Echo("Scan range: "+camera.AvailableScanRange.ToString("N0")+" m");     
} 
 
string VectorToString(Vector3D vector, int decimals, string delimiter)      
{      
    return Math.Round(vector.GetDim(0), decimals) + delimiter + Math.Round(vector.GetDim(1), decimals) + delimiter + Math.Round(vector.GetDim(2), decimals);      
}
