C# Class burningmime.curves.SplineBuilder

Wraps a CurveBuilder and Spline together. Allows you to add data points as they come in and generate a smooth spline from them without doing unnecessary computation.

Public Methods

Method	Description
Add ( System.Windows.Vector p ) : bool	Adds a data point.
Clear ( ) : void	Clears the SplineBuilder.
Sample ( System.Double u ) : System.Windows.Vector	Gets the position of a point on the spline that's close to the desired point along the spline. For example, if u = 0.5, then a point that's about halfway through the spline will be returned. The returned point will lie exactly on one of the curves that make up the spline.
SplineBuilder ( System.Double pointDistance, System.Double error, int samplesPerCurve ) : System.Diagnostics
Tangent ( System.Double u ) : System.Windows.Vector	Gets the tangent of a point on the spline that's close to the desired point along the spline. For example, if u = 0.5, then the direction vector that's about halfway through the spline will be returned. The returned value will be a normalized direction vector.

Method Details

Add() public method

Adds a data point.

public Add ( System.Windows.Vector p ) : bool
p	System.Windows.Vector	Data point to add.
return	bool

Clear() public method

Clears the SplineBuilder.

public Clear ( ) : void
return	void

Sample() public method

Gets the position of a point on the spline that's close to the desired point along the spline. For example, if u = 0.5, then a point that's about halfway through the spline will be returned. The returned point will lie exactly on one of the curves that make up the spline.

public Sample ( System.Double u ) : System.Windows.Vector
u	System.Double	How far along the spline to sample (for example, 0.5 will be halfway along the length of the spline). Should be between 0 and 1.
return	System.Windows.Vector

SplineBuilder() public method

public SplineBuilder ( System.Double pointDistance, System.Double error, int samplesPerCurve ) : System.Diagnostics
pointDistance	System.Double
error	System.Double
samplesPerCurve	int
return	System.Diagnostics

Tangent() public method

Gets the tangent of a point on the spline that's close to the desired point along the spline. For example, if u = 0.5, then the direction vector that's about halfway through the spline will be returned. The returned value will be a normalized direction vector.

public Tangent ( System.Double u ) : System.Windows.Vector
u	System.Double	How far along the spline to sample (for example, 0.5 will be halfway along the length of the spline). Should be between 0 and 1.
return	System.Windows.Vector
