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)
