\optpoint about pst-optexp HOT 6 CLOSED

Can you give a short example which shows the potential use of an \optpoint? At the moment I have no idea how that macro could work.

from pst-optexp.

\optpoint[angle=X, beamdivergence=Y](A)
this makes sense only as a starting point of a widebeam of course
i have just started jusing optexp so maybe i'm missing something and this does not make sense at all :)

from pst-optexp.

I would consider the angle and beamdivergence as properties of the beam and not associate to a point (or node). Although this could make sense as a kind of source:

\pnodes(0,1){A}(5,1){B}
\optsource[beamdiv=10, beamangle=0](A)
\lens(A)(B)
\drawwidebeam{1-2}

or one could have an \optbox declared as source:

\pnodes(0,1){A}(5,1){B}
\optbox[position=start, beamdiv=10, beamwidth=0.1, beamangle=0](A)
\lens(A)(B)
\drawwidebeam{1-2}

If this would be helpful for you, I can try to integrate this functionality.

from pst-optexp.

right now my solution is a optplane at the end and a optbox at the start, drawing the widebeam from end to start and by this i have a "focused" beam at the optbox, this works of course but your last solution
\optbox[position=start, beamdiv=10, beamwidth=0.1, beamangle=0](A)
would be even nicer

The new version 4.9 has an \optsource component:

\documentclass{standalone}
\usepackage{pst-optexp}
\begin{document}
\begin{pspicture}(5,2)
  \pnodes(1.5,1){A}(5,1){B}
  \optsource[innerlabel, beamdiv=10, beamangle=10](A)(B){Laser}
  \lens[lens=2 2 2](A)(B)
  \optplane(B)
  \drawwidebeam{-}
  \drawbeam[linecolor=red]{-}
\end{pspicture}
\end{document}

Note, that I changed the beam alignment behavior in version 4.10.
