Member Function Documentation

int decCurveBezier::AddPoint

(

const decCurveBezierPoint &

point )

Adds a point returning the index where it has been added.

int decCurveBezier::FindPointPriorTo

(

float

coordinate )

const

Retrieves the index of the point with the x coordinates matching the given x coordinate or the point which lies closest on the smaller side.

This method can be used to find the interval a point is located in by returning the most prior point. Retrieves -1 if there are no points satisfying this criteria.

int decCurveBezier::GetInterpolationMode

(

)

const [inline]

Retrieves the interpolation mode.

const decCurveBezierPoint& decCurveBezier::GetPointAt

(

int

position )

const

Retrieves the point at the given position.

int decCurveBezier::GetPointCount

(

)

const [inline]

Retrieves the number of points.

decCurveBezier& decCurveBezier::operator=

(

const decCurveBezier &

curve )

Sets the curve from another curve.

void decCurveBezier::RemoveAllPoints

(

)

Removes all points.

void decCurveBezier::RemovePointFrom

(

int

position )

Removes a point from the given position.

void decCurveBezier::SetInterpolationMode

(

int

mode )

Sets the interpolation mode.
