Detailed Description

concrete dataset representing a path defined by Bezier curves.

vtkPath provides a container for paths composed of line segments, 2nd-order (quadratic) and 3rd-order (cubic) Bezier curves.

Tests:

vtkPath (Tests)

Member Typedef Documentation

typedef vtkPointSet vtkPath::Superclass

Definition at line 40 of file vtkPath.h.

Member Enumeration Documentation

enum vtkPath::ControlPointType

Enumeration of recognized control point types:

• MOVE_TO: Point defining the origin of a new segment, not connected to the previous point.
• LINE_TO: Draw a line from the previous point to the current one
• CONIC_CURVE: 2nd order (conic/quadratic) point. Must appear in sets of 2, e.g. (0,0) MOVE_TO (0,1) CONIC_CURVE (1,2) CONIC_CURVE defines a quadratic Bezier curve that passes through (0,0) and (1,2) using (0,1) as a control (off) point.
• CUBIC_CURVE: 3rd order (cubic) control point. Must appear in sets of 3, e.g. (0,0) MOVE_TO (0,1) CUBIC_CURVE (1,2) CUBIC_CURVE (4,0) CUBIC_CURVE defines a cubic Bezier curve that passes through (0,0) and (4,0), using (0,1) and (1,2) as control (off) points.
