Detailed Description

concrete dataset representing a path defined by Bezier curves.

vtkPath provides a container for paths composed of line segment and 2nd/3rd order Bezier curves.

Member Typedef Documentation

typedef vtkPointSet vtkPath::Superclass

Definition at line 39 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.

Reimplemented from vtkDataSet.

int vtkPath::GetDataObjectType ( )

inlinevirtual

Return what type of dataset this is.

Reimplemented from vtkDataSet.
