[Radiance-general] Re: water - any news???

A P.S. to my last message.  The total commands should have -of as  
well, to correspond to the -df of pvalue:

vwrays -vf pool_par.vf -x 1000 -y 1000 -ff \
	| rtcontrib -V+ -ff -f pool_coords.cal \
		-b floor_bin -bn 7500 -o '!total -if22500 -of | pvalue -r -h +Y 150  
+X 50 -df > floor_caustics.pic' -m floor \
		-b s_wall_bin -bn 3000 -o '!total -if9000 -of | pvalue -r -h +Y 30  
+X 100 -df > s_wall_caustics.pic' -m s_wall \
		-b n_wall_bin -bn 3000 -o '!total -if9000 -of | pvalue -r -h +Y 30  
+X 100 -df > n_wall_caustics.pic' -m n_wall \
		-b e_wall_bin -bn 5000 -o '!total -if15000 -of | pvalue -r -h +Y 50  
+X 100 -df > e_wall_caustics.pic' -m e_wall \
		-b w_wall_bin -bn 5000 -o '!total -if15000 -of | pvalue -r -h +Y 50  
+X 100 -df > w_wall_caustics.pic' -m w_wall \
		pool.oct

I'm sure I made other mistakes as well, which you'll no doubt discover.

Also, the files I attached after my signature (assuming they made it)  
are from my "Applying the Radiance rtcontrib program" talk at last  
year's Radiance Workshop <http://www.radiance-online.org/radiance- 
workshop5/2006_Radiance_Workshop/>.  These offer an example of  
applying rtcontrib in a similar context, where I've worked out the  
solid angle factors to get correct irradiance units.
