Hi there,

i need some hint how i can create segments for a spline object. i already know how to create a spline (with a single segment), and in the help file i can only find commands to get the segment sount and such stuff, but i cannot fine something to create segments.

any help is welcome.

cheers and thanks,
ello

SplineObject::ResizeObject() allows you to change the segment count.
SplineObject::GetSegmentW() return the writeable array of segments to set how many points per segment.

Also have a look at VariableChanged structure and the MSG_SEGMENTS_CHANGED message for a more low-level approach.

here an example which creates a spline with two segments.

  
SplineObject *spline = NULL;  
spline = SplineObject::Alloc(0, Tlinear);  
if (!spline) return FALSE;  
  
spline->ResizeObject(4, 2);  
  
Segment *seg = spline->GetSegmentW();  
seg[0].cnt = 2;  
seg[1].cnt = 2;  
  
Vector *points = spline->GetPointW();  
  
points[0] = Vector(0,0,0);  
points[1] = Vector(0,100,0);  
points[2] = Vector(0,200,0);  
points[3] = Vector(0,300,0);

cheers,
Matthias
