How to do curved arrows?

[István]

Dear Group,

is there a way to draw curves with arrowheads in a convenient way?
I did not find anything relevant in the doc.center, nor in the group
archives.

Arrow[] is just like Line[], i.e. it can have any number of points.
Just generate the list of points for the curve, then wrap it in Arrow[].

Graphics[Arrow[{{0, 0}, {0, 1}, {1, 1}}]]

Hi,

Arrow[] can act as a wrapper for Line or Tube Primitives. These Lines or
Tubes can consist of arbitary segments (e.g. approximating a curve). Or
you can use Arrow[pts] directly...

Arrow[Tube[
Table[{Cos[phi], Sin[phi], .2 phi}, {phi, 0, 10,
0.1}]]] // Graphics3D

Regards,
Yves

It is certainly possible to draw curves with arrowheads. For example,

Show[Graphics@{Circle[{0, 0}, .5, {0, Pi/2}],
Arrow[{{.5, 0}, {.5, -.1}}, .1]}]

Thank you all for the answers,
I should have figured the solution out by my own.
Nevertheless, it would seem convenient to me to have a more general
arrow wrapper, which would be able to make arrows (that is, attach an
arrowhead) directly from e.g. BezierCurve primitives.

Thanks again
