Hi all,
It seems you cannot apply a boolean operation between a mesh2 object and a
solid? Or it computes no new surfaces?
Probably I'm missing something.
Thanks, Dick
My code:
#declare myBox = mesh2 { // a simple cube
vertex_vectors {
8,
<0,0,0>, <1,0,0>, <1,1,0>, <0,1,0>, <0,0,1>, <1,0,1>, <1,1,1>, <0,1,1>
}
face_indices {
12,
<0,2,3>, <0,1,2>, <0,1,5>, <0,5,4>, <1,5,2>, <5,6,2>, <2,6,7>, <2,7,3>,
<0,3,7>, <0,7,4>, <4,5,7>, <5,6,7>
}
inside_vector <0.5,0.5,0.5>
texture {pigment {rgb <0,1,0>}}
}
difference {
object { myBox }
box {
<0.25, -1, 0.25>
<0.75, 3, 0.75>
rgb <1,0,0>
}
}

keyword to 2nd box ;-)

Typo aside, it is a good idea to have a default texture. I like a bright
one so it is obvious if a texture is missing in a CSG.
#default{ texture{ pigment { colour rgb <1.0,0.0,1.0 > }} }

Same here. I rotated the box around to see the hole--red hole in a green box.
Looks successful (with lights, that is-- heh heh ;-) )

Hi all,
I assumed because the rgb keyword is enough for a box it was
also enough when in a bolean operation. As it turnes out you have to use the
texture keyword.
Thanks all!

Or actually just a pigment keyword--in which case, POV-Ray will supply a
'default' finish (which is ambient .1 and diffuse .6, per the documentation at
3.5.3.1 and 3.5.3.2)
