Dear list,
I want to draw paths between points which are bent by a certain angle. The code in the MWE below works well but I was thinking that the expert here can surely improve it and suggest a nicer syntax. looks like a challenge for Alan ... isn't it also a bit 3d (2.5d)?
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.
