Just a simple star with a few facets.
I made this star as part of an Esperanto flag, since my wife is learning
Esperanto. Since it's so simple I'll cheat a little and just post the source
code here in case anyone is interested...
Regards,
Dave Blandston
#local StarPoint = object {
intersection {
box {<-1, -.08, -1> <1, .08, 1>}
plane {z, 0 inverse rotate 70 * x rotate -54 * y translate -1 * z}
plane {z, 0 inverse rotate 70 * x rotate 54 * y translate -1 * z}
plane {z, 0 inverse rotate 110 * x rotate 72 * y translate 1 * z}
plane {z, 0 inverse rotate 110 * x rotate -72 * y translate 1 * z}
plane {z, 0 rotate 110 * x rotate -54 * y translate -1 * z}
plane {z, 0 rotate 110 * x rotate 54 * y translate -1 * z}
plane {z, 0 rotate 70 * x rotate 72 * y translate 1 * z}
plane {z, 0 rotate 70 * x rotate -72 * y translate 1 * z}
} //intersection
translate 1 * z
} //object
#local Star = object {
union {
#local I = 0;
#while (I < 5)
object {StarPoint rotate (I * 72) * y}
#local I = I + 1;
#end //#while
} //union
rotate -90 * x
} //object

With front facets is very cool.
