High!
As I announced recently, I would like to add a code display feature to
my includes presentation table (see attachment). So I would like to know
whether it is possible to read ASCII text line by line via #read... the
manual says data to be read in have to be separated by commas. The other
way would be to explicitly store the whole text "manually" into an array
whose contents then are rendered in the display section of the table's
glass lid... but this appears rather clumsy to me!
And, concerning the rendering of the test version - why is the red
transparent text not completely cast as shadow?
See you in Khyberspace!

Yes, that is possible indeed. Write a file with each text item separated
by commas (and I think they also should be within " ", not sure
however), then read the file using:
#while (defined(your text file))
#read (....)
....
#end
and apply each read text item to where/what you intend. Reading will
automatically stop when reaching the end of the file.

I cannot tell just from the image unfortunately.

I probably should have written this better as:
#while (defined(your text file))
#read (....)
....
apply each read text item to where/what you intend. Reading will
automatically stop when reaching the end of the file.
....
#end

As the file to read the data from is the original stones1.inc file, it
probaby would be better to write a C++ program which reads in the text
line-wise, generates PoV-Ray array definition code from these lines and
then stores it under "stones1_inc.inc"!

I've done so... see my recent entry on povray.programming!

Because you accidently told POV-Ray to render it this way? :-P
I can't tell what's wrong without seeing the code. Maybe you set
no_shadow on that text without noticing?

Hi(gh)!
After I got together the text array, I wonder whether it is possible to
have the display elements in a glowing emitting media with does not fade
to invisible against a white background... as want to use radiosity
later on, just using ambient 1 would be useless!
See you in Khyberspace!

Purely emitting media /always/ fades to invisible against a white
background (unless you're rendering to a high dynamic range file format,
i.e. HDR or openEXR).
