Usage
vtkArcSource is a source object that creates an arc defined
by two endpoints and a center. The number of segments
composing the polyline is controlled by setting the object
resolution.
To create an instance of class vtkArcSource, simply invoke
its constructor as follows
obj = vtkArcSource
Methods
The class vtkArcSource has several methods that can be used.
They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkArcSource class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkArcSource = obj.NewInstance ()
* vtkArcSource = obj.SafeDownCast (vtkObject o)
* obj.SetPoint1 (double , double , double ) - Set position
of first end point.
* obj.SetPoint1 (double a[3]) - Set position of first end
point.
* double = obj. GetPoint1 () - Set position of first end
point.
* obj.SetPoint2 (double , double , double ) - Set position
of other end point.
* obj.SetPoint2 (double a[3]) - Set position of other end
point.
* double = obj. GetPoint2 () - Set position of other end
point.
* obj.SetCenter (double , double , double ) - Set position
of the center of the circle that define the arc. Note: you
can use the function vtkMath::Solve3PointCircle to find
the center from 3 points located on a circle.
* obj.SetCenter (double a[3]) - Set position of the center
of the circle that define the arc. Note: you can use the
function vtkMath::Solve3PointCircle to find the center
from 3 points located on a circle.
* double = obj. GetCenter () - Set position of the center of
the circle that define the arc. Note: you can use the
function vtkMath::Solve3PointCircle to find the center
from 3 points located on a circle.
* obj.SetResolution (int ) - Divide line into resolution
number of pieces. Note: if Resolution is set to 1
(default), the arc is a straight line.
* int = obj.GetResolutionMinValue () - Divide line into
resolution number of pieces. Note: if Resolution is set to
1 (default), the arc is a straight line.
* int = obj.GetResolutionMaxValue () - Divide line into
resolution number of pieces. Note: if Resolution is set to
1 (default), the arc is a straight line.
* int = obj.GetResolution () - Divide line into resolution
number of pieces. Note: if Resolution is set to 1
(default), the arc is a straight line.
* obj.SetNegative (bool ) - Use the angle that is a negative
coterminal of the vectors angle: the longest angle. Note:
false by default.
* bool = obj.GetNegative () - Use the angle that is a
negative coterminal of the vectors angle: the longest
angle. Note: false by default.
* obj.NegativeOn () - Use the angle that is a negative
coterminal of the vectors angle: the longest angle. Note:
false by default.
* obj.NegativeOff () - Use the angle that is a negative
coterminal of the vectors angle: the longest angle. Note:
false by default.
