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.

void vtkPath::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDataSet.

int vtkPath::GetDataObjectType ( )

inlinevirtual

Return what type of dataset this is.

Reimplemented from vtkDataSet.

Definition at line 43 of file vtkPath.h.
