Hello there.

    I am having a problem in getting windows into a curved surface, as
in the rim of a cylinder.   I can place windows onto any flat surface
quite easily, but putting them onto irregular shapes has me tossed.
Any hints.

Thanks Alex

Try this and see if it's what you had in mind.

  camera{location<0,0,-5>look_at<0,0,0>}
  light_source{<-5,0,-20>rgb 1}

  union{
  intersection{
  cylinder{y*-1,y*1,1 open pigment{rgbf<1,1,0,1>}
  finish{ambient .4 diffuse .1 specular 1 roughness .0001 reflection .05}}
  plane{z,-.8 pigment{rgbft 1}}rotate 0*x}

  intersection{
  cylinder{y*-2,y*2,1 open pigment{rgb 1}}
  box{-1,1 scale<.7,1,.6>translate z*-1.35 inverse pigment{rgbft 1}}}
  rotate 0*y}

Hello Ken,

    That worked perfectly, and after studying the code, it was a lot simpler
than what I had been experimenting with, trying to cut open cylinders into
arcs and using the intersection of the arcs and the object.  again thank you.

btw. your images in pov.binaries.images are excellent.
 regards Alex
