| double Distance | ( | CurveLocationDetailCR | other | ) | const |
Return distance between point fields of this and other.
| bool Interpolate | ( | bvector< double > const & | param, |

| ) | const |
Use the componentIndex and componentFraction to interpolate doubles.
| ValidatedCurveLocationDetail Interpolate | ( | double | fraction, |
| CurveLocationDetailCR | dataB | ||
| ) | const |
construct an interpolated detail.
the return has (1) the curve pointer from the first, (2) simple interpolation of fraction, point, and "a" value, (3) component data based on the interpolated fraction and the componentCount from the first. The result is marked valid only if the inputs have matching curve pointers and component counts. This operation makes clear sense if both curved details are from the same curve and (with allowance for start-end matchup) within the same component (linesegment ?) of that parent. It may or may not make sense if it spans interiors of two components of the same curve. It almost certainly does not make sense between curves.
| ValidatedDRay3d PointAndUnitTangent | ( | ) | const |
Try to evalute the point and unit tangent at the detail's fraction.
| void SetComponentFractionFromFraction | ( | double | globalFraction, |
| size_t | numComponent | ||
| ) |
Set the componentIndex, numComponent, componentFraction, and fraction.
(Component fraction and index are computed from global fraction and indices) All other data (point, curve pointer, a) is left unchanged.

| double SetDistanceFrom | ( | DPoint3dCR | refPoint | ) |

| void SetFractionFromComponentFraction | ( | double | componentFraction, |
| size_t | componentIndex, | ||
| size_t | numComponent | ||
| ) |
Set the componentIndex, numComponent, componentFraction, and fraction.
(Global fraction is computed as (componentIndex + componentFraction)/ numComponent. All other data (point, curve pointer, a) is left unchanged.
| void SetMaxDistance | ( | ) |
set distance to very large value.
| void SetSingleComponentData | ( | ) |
copy fraction to componentFraction and set component index and count for single component.
| void SetSingleComponentFractionAndA | ( | double | fraction, |
| double | a | ||
| ) |
Set fraction and a fields from parameters. Make the component fraction match. Set componentIndex and numComponentIndex to 0 and 1.
