Curve Orientation Operator
Adds an orientation to a curve segment or to a start point.
Signatures
- elmt1 ^ orient
Details
The operator allows to add an orientation direction to a curve starting point or to a curve segment that gets added to a curve. An orientation direction is a vector that defines the orientation at the terminal point of the segment (see oriented curves). The orientation along the segment is interpolated implicitly.
Orientations on curves can be used to control the behavior of certain functions like extrusion.
A two-segment-curve with given orientation directions (blue) at the vertex positions and interpolations along the line (light blue).
Example
curve c1 = <[0,0]>^<[0,0,1]> -> arc(<[1,0]>,PI)^<[0,1,0]>
Return value
An oriented curve segment.
