[NTG-context] Check if two paths intersect in Metafun

[Jairo A. del Rio]

Hi, list. I've got a question about paths and intersections. The following:


\starttext

\startMPpage

path p[];


p[1] = fullcircle scaled 2cm;

p[2] = unitsquare shifted (4cm,6cm);


if (known (p[1] intersectionpoint p[2])):


draw textext("yes");


else:


draw textext("no");

fi;


\stopMPpage

\stoptext

yields an error message: "The paths don't intersect". Is there a way to
intercept this error message and trigger an action instead? Thank you in
advance.

Best regards,

Jairo
