Constructor & Destructor Documentation

◆ ON_CurveTreeBezier() [1/2]

ON_CurveTreeBezier::ON_CurveTreeBezier ( )

C++ defaults for destruction, copy construction, and operator= work fine.

◆ ON_CurveTreeBezier() [2/2]

ON_CurveTreeBezier::ON_CurveTreeBezier ( const ON_BezierCurve bezier_curve)

Description: Copy constructs the bezier_curve and then sets the leaf box.

Member Function Documentation

◆ IsFartherThan() [1/3]

bool ON_CurveTreeBezier::IsFartherThan ( double  d,
const class ON_BoundingBox box 
) const

◆ IsFartherThan() [2/3]

bool ON_CurveTreeBezier::IsFartherThan ( double  d,
const class ON_CurveTreeBezier other 
) const

Description: Quickly determine if the shortest distance from the bezier surface to this bezier curve is greater than d. Parameters: d - [in] distance (> 0.0) other - [in] Returns: True if the shortest distance from the other bezier to this bezier curve is greater than d. It is not the case that false means that the shortest distance is less than or equal to d.

◆ IsFartherThan() [3/3]

bool ON_CurveTreeBezier::IsFartherThan ( double  d,
const class ON_SurfaceTreeBezier other 
) const

◆ MaximumDistanceTo() [1/2]

double ON_CurveTreeBezier::MaximumDistanceTo ( const ON_CurveTreeBezier other) const

Description: Quickly find an upper bound on the distance between the two bezier curves. Parameters: other - [in] another bezier curve Returns: A distance that is greater than or equal to the longest distance from this curve to the other curve. Put another way, if Q is any point on this bezier curve and P is any point on the other bezier curve, then then P.DistanceTo(Q) <= MaximumDistanceTo(other).

◆ MaximumDistanceTo() [2/2]

double ON_CurveTreeBezier::MaximumDistanceTo ( const ON_SurfaceTreeBezier other) const

◆ MinimumDistanceTo() [1/2]

double ON_CurveTreeBezier::MinimumDistanceTo ( const ON_CurveTreeBezier other) const

Description: Quickly find a lower bound on the distance between the two bezier curves. Parameters: other - [in] another bezier curve Returns: A distance that is less than or equal to the shortest distance from this curve to the other curve. Put another way, if Q is any point on this bezier curve and P is any point on the other bezier curve, then then P.DistanceTo(Q) >= MinimumDistanceTo(other).

◆ MinimumDistanceTo() [2/2]

double ON_CurveTreeBezier::MinimumDistanceTo ( const ON_SurfaceTreeBezier other) const

◆ SetBezier()

bool ON_CurveTreeBezier::SetBezier ( const ON_BezierCurve bezier_curve)

Description: Sets the bezier curve and its leaf box. Parameters: bezier_curve - [in] Returns: True if bezier_curve is valid. See Also: ON_CurveTreeBezier::SetLeafBox

◆ SetLeafBox()

bool ON_CurveTreeBezier::SetLeafBox ( )

Description: Sets m_leafbox to be the smallest curve leaf box that contains this bezier curve. Returns: True if this bezier is valid and the leaf box is set.
