Properties
Name Type Attributes Description
v Number | Object Either the index or value of one of the types [TYPE_VECTOR, TYPE_LINE]. The direction If no text transformer is used, the object is just converted using the objectToString function
fixedDir Object <optional>
 A fixed direction from which to compute the angle from
useAngle Number <optional>

(static) fromPoints(p0, p1, p2, useAngleopt) → {CreateInfo}

Creates an angle from three points. The angle is measured around the middle one. The reference point is placed at the middle point
Parameters:
Name Type Attributes Description
p0 Number | Object Either the index or value of a TYPE_POINT
p1 Number | Object Either the index or value of a TYPE_POINT
p2 Number | Object Either the index or value of a TYPE_POINT
useAngle Number <optional>

CreateInfo

(static) fromVectorsOrLines(v0, v1, useAngleopt) → {CreateInfo}

Creates an angle from two objects that can each be either lines or vectors. The reference point is placed where the infinitl lines through the objects intersect
Parameters:
Name Type Attributes Description
v0 Number | Object Either the index or value of one of the types [TYPE_VECTOR, TYPE_LINE]
v1 Number | Object Either the index or value of one of the types [TYPE_VECTOR, TYPE_LINE]
useAngle Number <optional>
