I'm hoping someone can clear up some confusion I'm feeling.
In the CSG Intersection documentation for POV 3.1, it says that
intersection leaves just those portions of the two object which exist
within both objects.
A plane is an infinately thin object which extends infinatly in two
directions.
Therefore, it would seem to me that, if you intersected two planes, you
would get a line; if you intersected three planes... provided they
intersected at all... you would get a point.
But if I do:
intersection
{
plane { -y, -0.555 }
plane
{
x, 0
rotate -4.3012223*z
translate <.59831012, .555, 0>
}
plane
{
-x, 0
rotate 4.3012223*z
translate <-.59831012, .555, 0>
}
}
scale <1, .5, 1>
}
I get a strange, flat-bottomed V shape.
Why?

Then maybe read the chapter on the plane object again, esp. the fourth
paragraph.
