I wasn't thinking about a 3D application here, just a little bend on the
path to go around other elements in my drawing without having to think
about explicit control points (like the second example in my original
post). In the meantime I have improved the defintion of the macro to
avoid double computation of the angle:
vardef bend(expr a,b,phi) =
save x ;
x := angle(b-a) ;
a{dir(x+phi)} .. {dir(x-phi)}b
enddef ;
So currently the applied syntax is
drawarrow bend(z1, z2, 30) ;
However, I would prefer something like
drawarrow z1 bend(30) z2 ;
I'm not sure whether this is possible though. Actually I'm reading the
MetaPost manual right know because my MP skills are rather poor.
