[Radiance-general] Re: output in holodeck file

[Greg Ward]

Hi Olga,

There is no method provided for looking at the ray values in a holodeck 
in ASCII format, as I never found this useful even for debugging 
purposes.  The data is organized in a very hard-to-understand way, and 
the individual ray values are so many that I'm not sure what you would 
do with them if you had them.  However, there are a couple of useful 
utilities for holodecks that you might enjoy:

rhinfo	- prints the header and grid information from a holodeck file
rhcopy	- copies information from one holodeck to another, or from a 
picture to a holodeck
rhoptimize	- optimizes beam placements in a holodeck for more efficient 
rendering
rhpict	- reconstructs a picture from beams stored in a holodeck

What purpose did you have in mind for recovering ray values?
-Greg
