Hi, this might be easy for most of you, but after reading some tutorials I
still wasn't able to do it. So, I would be very pleased and grateful if
somebody could help me out.
I have generated a scene of a molecule consisting of atoms (spheres) and
bonds (cylinders) in POV-Ray.
Now I want certain spheres look like metal balls with non reflecting text on
top of it, like it is printed. More specifically, I want to put the atom
identification on top of the sphere. I have tried something with
object_pattern but probably did something wrong??
Any comments and suggestions are very welcome,
thanx in advance,
Kees

But you create your sphere remote from origin.
You should create them at origin, texture them with text on top THEN
translate them :-)

Hi Kees,
Here's a simple example of writing text onto a sphere. The text object
'YourText' starts at the origin and is 2 units thick, stretching from z=0 to
z=2. Translating it brings it in line with the surface of a 1 unit radius
sphere centred at the origin.
The pigment declared as 'TextPigment' uses the object as a pigment and sets
the 3D space inside the object to a yellow colour with the 3D space outside
the object being set to transparent. The texture is applied to the object
layered on top of another texture, which in this case is red, but could
equally well be the your shiny texture.
camera {location <0,0,-20> look_at <0,0,0> angle 30}
light_source {<-30, 10, -30> color rgb 1}
#declare YourText = text {ttf "crystal.ttf", "POV-Ray", 2, 0
translate <-1.5,-0.5,-3> }
#declare TextPigment = pigment {object {YourText rgbt 1 rgb <1,1,0>}}
sphere {0,3
texture {pigment {color rgb <1,0,0>}}
texture {pigment {TextPigment}}
}
Regards,
Chris B.

tx for the reply, indeed i considered your suggestion. However, since the
pov file was generated with the program PLATON using the crystal structure
of the compound i made myself, the spheres of interest are not at the
origen. In addition, most atoms (spheres) occur more then once in the
scene. Therefore I was hoping to be able to write a general texture or
pigment part for each type of sphere so I don't have to translate the text
for all of them.
I have tried something similar as performed in the folowing pov file:
http://csi.chemie.tu-darmstadt.de/ak/immel/script/redirect.cgi?filename=http://csi.chemie.tu-darmstadt.de/ak/immel/grap
hics/povray35/object_pattern.html
or see below,
but that didn't work. In here they made an text object and sticket that onto
an cylinder. I was hoping to be able to something similar.

there's a guy in the binary group who has some cool txt on spheres, maybe it
would work for you? the thread is called "RSOCP overkill"
Hope it helps-
