ON_SurfaceTreeBezier::ON_SurfaceTreeBezier ( const ON_BezierSurface bezier_surface)

Member Function Documentation

◆ IsFartherThan() [1/4]

bool ON_SurfaceTreeBezier::IsFartherThan ( double  d,
const ON_3dPoint P

Description: Quickly determine if the shortest distance from the point P to this bezier curve is greater than d. Parameters: d - [in] distance (> 0.0) P - [in] Returns: True if the shortest distance from the point P 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() [2/4]

bool ON_SurfaceTreeBezier::IsFartherThan ( double  d,
const ON_BoundingBox bbox 
) const

Description: Quickly determine if the shortest distance from the bounding box to this bezier curve is greater than d. Parameters: d - [in] distance (> 0.0) bbox - [in] Returns: True if the shortest distance from the bounding box 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() [3/4]

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

Description: Quickly determine if the shortest distance from the other bezier 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() [4/4]

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

Description: Quickly determine if the shortest distance from the other bezier 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.

◆ MaximumDistanceTo() [1/4]

double ON_SurfaceTreeBezier::MaximumDistanceTo ( const class ON_SurfaceTreeBezier stbez) const

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

◆ MaximumDistanceTo() [2/4]

double ON_SurfaceTreeBezier::MaximumDistanceTo ( const ON_CurveTreeBezier other) const

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

◆ MaximumDistanceTo() [3/4]

double ON_SurfaceTreeBezier::MaximumDistanceTo ( ON_3dPoint  P) const

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

◆ MaximumDistanceTo() [4/4]

Description: Quickly find an upper bound on the distance between the bezier surface and a bounding box. Parameters: bbox - [in] Returns: A distance that is greater than or equal to the longest distance from this surface to the bounding box.

Description: Quickly find a lower bound on the distance between this surface and a bezier curve. Parameters: other - [in] a bezier curve Returns: A distance that is less than or equal to the shortest distance from this surface to the curve.
