Constructor & Destructor Documentation

◆ CRhinoStretchSpaceMorph()

CRhinoStretchSpaceMorph::CRhinoStretchSpaceMorph ( )

Member Function Documentation

◆ GetStretchFactor() [1/2]

double CRhinoStretchSpaceMorph::GetStretchFactor ( double  new_length)

Description: Takes a number that represents a new stretch axis length and converts it to a stretch factor value Parameters: double new_length - [in] Returns: A stretch factor, or ON_UNSET_VALUE if m_stretch_axis.Length() is zero.

◆ GetStretchFactor() [2/2]

double CRhinoStretchSpaceMorph::GetStretchFactor ( ON_3dPoint  stretch_point)

Description: Takes a point to stretch to and converts it to a stretch factor value Parameters: ON_3dPoint stretch_point - [in] Returns: A stretch factor if a valid point, otherwise returns ON_UNSET_VALUE

◆ IsIdentity()

bool CRhinoStretchSpaceMorph::IsIdentity ( const ON_BoundingBox bbox) const
virtual

virtual ON_SpaceMorph override

Reimplemented from ON_SpaceMorph.

◆ IsValid()

bool CRhinoStretchSpaceMorph::IsValid ( ) const

Description: Identifies whether the m_stretch_axis and m_stretch_factor are set and valid. Returns: true if m_stretch_axis and m_stretch_factor are valid

◆ IsValidStretchFactor()

static bool CRhinoStretchSpaceMorph::IsValidStretchFactor ( double  stretch_factor)
static

◆ MorphPoint()

ON_3dPoint CRhinoStretchSpaceMorph::MorphPoint ( ON_3dPoint  pt) const
virtual

virtual ON_SpaceMorph override

Implements ON_SpaceMorph.

◆ SetStretchFactor()

bool CRhinoStretchSpaceMorph::SetStretchFactor ( double  stretch_factor)

Description: If the stretch_factor is valid, it sets the m_stretch_factor and builds the ON_BezierCurve m_stretch_function Parameters: double stretch_factor - [in] Returns: True if stretch_factor is valid

Member Data Documentation

◆ m_stretch_axis

ON_Line CRhinoStretchSpaceMorph::m_stretch_axis

Line along which to perform the stretch operation.

◆ m_stretch_factor

double CRhinoStretchSpaceMorph::m_stretch_factor

◆ m_stretch_function

ON_BezierCurve CRhinoStretchSpaceMorph::m_stretch_function

NOTE: The m_stretch_function and m_stretch_factor are for expert users only. It is prefered to use the GetStretchFactor and SetStretchFactor functions instead.

The m_stretch_function is a monotone increasing function f() such that: f(0) = 0, f(1) = 1, f'(0) = 0, f'(1) = 1
