Does MetaFun provide some macro to draw oriented paths? I would like it to basically add a small arrow *in the middle* of the path? Such a macro
draworiented somepath somespecs ;
would have to act like
drawarrow firsthalf(somepath) somespecs ; draw secondhalf(somepath) somespecs ;
Is it available already, or should I roll my own?
Hm. I came up with def draworiented expr c = path _c_ ; _c_ := c ; do_draworiented enddef ; def do_draworiented text t = draw _c_ t ; drawarrow subpath(0, length(_c_)/2) of _c_ ; enddef; which works, although I have to do draworiented (reverse p1) Is there an easy way to have it work with draworiented reverse p1 ? -- Giuseppe "Oblomov" Bilotta
