Hi,

I have to parse large ASCII files that contain parameters for thousands
of spheres and their textures.
Such a ASCII file has a structure like

X   Y    Z     SIZE  COLOR
0.9 0.7  0.1  0.05  BLUE
0.8 0.6  0.1  0.03  YELLOW
....

Does anybody know how to parse such a file within a POVRAY script?

Another question, is there anywhere an example of how to store a
rendered image as a *.tif file?


Thanks a lot.    Oliver

Pov 3.1 has file I/O capabilities, so this would be no problem
provided that you first formatted the data to adhere to the 
requirements you can read about in the help docs. I'd suggest a simple
external program to reformat the data such that each X Y Z can
be read as a single vector <X,Y,Z>, size would be a single float
and the color should be an (RGB) vector so....

X    Y    Z    SIZE    COLOR
0.9  0.7  0.1  0.05    Blue

would become....

XYZ          SIZE     COLOR
<.9,.7,.1>,   .05,    <0,0,1>,
...
...

Note that all data elements must be seperated by a comma.
Check the docs for more info.
