Constructor & Destructor Documentation

decCurveBezier() [1/2]

decCurveBezier::decCurveBezier

(

)

Create a new bezier curve.

decCurveBezier() [2/2]

decCurveBezier::decCurveBezier

(

const decCurveBezier &

curve

)

Create copy of bezier curve.

~decCurveBezier()

decCurveBezier::~decCurveBezier

(

)

Clean up the bezier curve.

Member Function Documentation

AddPoint()

int decCurveBezier::AddPoint

(

const decCurveBezierPoint &

point

)

Add point returning the index where it has been added.

FindPointPriorTo()

int decCurveBezier::FindPointPriorTo

(

float

coordinate

)

const

Index of the point with matching x coordinates or the point 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.

GetInterpolationMode()

eInterpolationModes decCurveBezier::GetInterpolationMode ( ) const

inline

Interpolation mode.

GetPointAt()

const decCurveBezierPoint& decCurveBezier::GetPointAt

(

int

position

)

const

Point at position.

Exceptions

deeInvalidParam	position is less than 0.
deeInvalidParam	position is larger or equal to GetPointCount()-1.

GetPointCount()

int decCurveBezier::GetPointCount ( ) const

inline

Number of points.

operator!=()

bool decCurveBezier::operator!=

(

const decCurveBezier &

curve

)

const

Curves are not equal.

operator=()

decCurveBezier& decCurveBezier::operator=

(

const decCurveBezier &

curve

)

Copy another curve to this curve.

operator==()

bool decCurveBezier::operator==

(

const decCurveBezier &

curve

)

const

Curves are equal.

RemoveAllPoints()

void decCurveBezier::RemoveAllPoints

(

)

Remove all points.

RemovePointFrom()

void decCurveBezier::RemovePointFrom

(

int

position

)

Remove point from the given position.

Exceptions

deeInvalidParam	position is less than 0.
deeInvalidParam	position is larger or equal to GetPointCount()-1.

SetDefaultBezier()

void decCurveBezier::SetDefaultBezier

(

)

Set curve to default bezier curve from (0,0) to (1,1).

SetDefaultLinear()

void decCurveBezier::SetDefaultLinear

(

)

Set curve to linear mapping from (0,0) to (1,1).

SetInterpolationMode()

void decCurveBezier::SetInterpolationMode

(

eInterpolationModes

mode

)

Set interpolation mode.

Exceptions

deeInvalidParam

mode is not a member of decCurveBezier::eInterpolationModes.
