16 | // .NAME vtkRpAxisActor - Create an axis with tick marks and labels |
---|
17 | // .SECTION Description |
---|
18 | // vtkRpAxisActor creates an axis with tick marks, labels, and/or a title, |
---|
19 | // depending on the particular instance variable settings. It is assumed that |
---|
20 | // the axes is part of a bounding box and is orthoganal to one of the |
---|
21 | // coordinate axes. To use this class, you typically specify two points |
---|
22 | // defining the start and end points of the line (xyz definition using |
---|
23 | // vtkCoordinate class), the axis type (X, Y or Z), the axis location in |
---|
24 | // relation to the bounding box, the bounding box, the number of labels, and |
---|
25 | // the data range (min,max). You can also control what parts of the axis are |
---|
26 | // visible including the line, the tick marks, the labels, and the title. It |
---|
27 | // is also possible to control gridlines, and specifiy on which 'side' the |
---|
28 | // tickmarks are drawn (again with respect to the underlying assumed |
---|
29 | // bounding box). You can also specify the label format (a printf style format). |
---|
30 | // |
---|
31 | // This class decides how to locate the labels, and how to create reasonable |
---|
32 | // tick marks and labels. |
---|
33 | // |
---|
34 | // Labels follow the camera so as to be legible from any viewpoint. |
---|
35 | // |
---|
36 | // The instance variables Point1 and Point2 are instances of vtkCoordinate. |
---|
37 | // All calculations and references are in World Coordinates. |
