Hi,
I need help to create a spline object. I tried to create a spline as follows:
var splobj = new(SplineObject);
var ptarr = new(array,3); // Points for my spline path
ptarr[0] = vector(0,0,0);
ptarr[1] = vector(100,100,100);
ptarr[2] = vector(200,200,200);
splobj->SetPoints(ptarr);
doc->InsertObject(splobj,NULL,NULL);
GeEventAdd(REDRAW_ALL);

But I cannot see any points as I specified. What is the problem?

It´s for polygonobjects but the same procedure

Is there any tutorial for handling spline object? I feel difficult to handle.
What is the difference between SetSegments() and SetTangents(). What is the difference between Segment Array and Tangent Array.

Segments are for multi-segmented splines, tangents are for Bezier splines. The format of these arrays are in the documentation. The update messages are completely analogous to the polygon object example (e.g. MSG_SEGMENTS_CHANGED). There's no MSG_TANGENTS_CHANGED since they are 1:1 to the points.

Still I couln't succeed in spline creation. _ _ I feel any sample code will be more useful. Can anybody help me? First time I am working with spline creation so confused bit.

Here's the simplest possible example:

    
    
    NewSplineObject(pointCount)  
    {  
      if (pointCount < 0) return FALSE;  
        
      var newObject = new(SplineObject);  
        
      var pointArray = new(array, pointCount);
    
    
    
    
      var i;  
      for (i = 0; i < pointCount; ++i)  
      {  
        pointArray[i] = vector(0.0);  
      }
    
    
    
    
      newObject->SetPoints(pointArray);  
        
      var variableChanged = new(VariableChanged);  
      var backupTags = new(BackupTags);  
        
      backupTags->Init(newObject);  
      variableChanged->Init(0, pointCount);  
      if (!newObject->Message(MSG_POINTS_CHANGED, variableChanged))  
      {  
        backupTags->Restore();  
        return FALSE;  
      }  
        
      newObject->Message(MSG_UPDATE);  
      return newObject;  
    }
    
    
    
    
      
    main()  
    {  
      var doc = GetActiveDocument();  
      doc->InsertObject(NewSplineObject(16), NULL, NULL);  
    }

And how to initialize the position of the points during this process (for example, taking the points of another spline).
