Thanks that helped! My documentation (ms-dos vertion) says OPEN would remove
the end CAPS .But
with you help I found that open only affects the lower end and you have to
close the high end yourself.
Even so 'sturm' has to be use on some complicated objects.
Here what I think is the basic setup.
sor { 5
<0,0>// p1 slope for p2 & p3
<0.2,0.3>// p2 without open this will be close to point <0,.3>
<0.6,0.7>// p3
<0,1>// p4 this is the point that you have to close yourself
<0,1> // p5 this is the last slope and effects p4 and p3
//sturm //open
pigment {rgb 1}
}
