emitTangents Method
Announce all points P on the contained curves such that the line containing spacePoint and P is tangent to
the contained curves in the view defined by options.vectorToEye.
- Strictly speaking, each tangent line lies in the plane through
Pwhose normal is the cross product of the curve tangent atPandoptions.vectorToEye. This is equivalent to tangency as seen in a view plane perpendicular tooptions.vectorToEye.
emitTangents(spacePoint: Point3d, announceTangent: (tangent: CurveLocationDetail) => any, options?: TangentOptions): void
| Parameter | Type | Description |
|---|---|---|
| spacePoint | Point3d | point in space. |
| announceTangent | (tangent: CurveLocationDetail) => any | callback to announce each computed tangent. The received CurveLocationDetail is reused internally, so it should be cloned in the callback if it needs to be saved. |
| options | TangentOptions | (optional) options for computing tangents. See TangentOptions for defaults. |
Returns - void
Defined in
- curve/CurveCollection.ts Line 109
