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()
|
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 |
◆ MorphPoint()
|
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 preferred 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
