JointOptions Class
- Control parameters for joint construction.
- Decision order is:
- if turn angle is greater than minArcDegrees, make an arc.
- if turn angle is less than or equal maxChamferTurnDegrees, extend curves along tangent to single intersection point.
- if turn angle is greater than maxChamferTurnDegrees, construct multiple lines that are tangent to the turn circle "from the outside", with each equal turn less than maxChamferTurnDegrees.
- otherwise make single edge.
Methods
| Name | Description | |
|---|---|---|
| constructor(leftOffsetDistance: number, minArcDegrees: number = 180, maxChamferDegrees: number = 90, preserveEllipticalArcs: boolean = false): JointOptions | Construct JointOptions. | |
| clone(): JointOptions | Return a deep clone. | |
| needArc(theta: Angle): boolean | return true if the options indicate this amount of turn should be handled with an arc. | |
| numChamferPoints(theta: Angle): number | Test if turn by theta should be output as single point. | |
| setFrom(other: JointOptions): void | Copy values of input options | |
| create(leftOffsetDistanceOrOptions: number | JointOptions): JointOptions Static | Parse a number or JointOptions up to JointOptions: |
Properties
| Name | Type | Description | |
|---|---|---|---|
| leftOffsetDistance | number | Offset distance, positive to left of base curve. | |
| maxChamferTurnDegrees | number | ||
| minArcDegrees | number | smallest arc to construct. | |
| preserveEllipticalArcs | boolean | Whether to offset elliptical arcs as elliptical arcs (true) or as B-spline curves (false, default). |
