h2. Basics - Pline

*pline* - a function that renders a 2 dimensional triangle by connecting points and lines.

pline(p1,p2,p3) :=

* concat("_pline",sp,point(p1{^}<0>{^}),sp,point(p2{^}<0>{^}),sp,point(p3{^}<0>{^}),sp,point(p1{^}<0>{^}),sp)

*Example*

p1=
* x = 0
* y = 0

p2 =
* x = -0.5
* y = 0

p3 =
* x = 0
* y = 0.86603

pline(p1,p2,p3) = _pline 0,0 -0.5,0 0,0.86603 0,0
