sectionArcWithIntermediateNormal Method
Deprecated Prefer sectionArcInPlaneOfInterpolatedNormal, which has expanded return type.
Create a section arc with start and end at positions A and B, and in plane with the normal at a fractional interpolation between.
sectionArcWithIntermediateNormal(angleA: LongitudeLatitudeNumber, intermediateNormalFraction: number, angleB: LongitudeLatitudeNumber): Arc3d
@returns arc in the plane defined by the normal at the intermediate point. If calculation fails, return an arc with zero matrix.
| Parameter | Type | Description |
|---|---|---|
| angleA | LongitudeLatitudeNumber | start point of arc (given as angles on this ellipsoid) |
| intermediateNormalFraction | number | fraction at which to interpolate normals at A and B to define arc plane |
| angleB | LongitudeLatitudeNumber | end point of arc (given as angles on this ellipsoid) |
Returns - Arc3d
arc in the plane defined by the normal at the intermediate point. If calculation fails, return an arc with zero matrix.
Defined in
- geometry3d/Ellipsoid.ts Line 549
