Curve Link Operator
Appends a curve segment to a curve or to a start point.
Signatures
- elmt1 -> segm1
- curve1 ->= segm1
Details
Binary operators that combines a start point or a curve with a curve segment to form a combined curve.
The first signature combines elmt1 with the new segment segm1 and returns the new curve. The two elements are not changed by this. This operator is left-associative and can be chained.
The second signature expands curve1 by segment code segm1 .
Example
curve triangle
triangle = <[1.0, 1.0]> -> <[2.0, 1.0]>
triangle ->= <[1.5, 2.0]>
triangle = triangle -><-
make extrusion( triangle, <[0.0, 0.0, 1.0]> )
Return value
A curve that results from the appending of the segment.
Parameters
- elmt1
-
Either a vector defining the starting point of a new curve or a curve. elmt1 is not modified by this way of applying the curve link operator.
- curve1
-
A curve object that gets modified by the addition of segm1.
- segm1
-
A curve segment that gets appended to the curve. This can either be a vector point (what implicitly adds a segment constructor of type line_to), or an explicit segment constructor.
