[Radiance-general] Deterministic calculations with Radiance

[Andrew McNeil]

Looks like you're missing the pipe symbol.

Try:
ximage someRendering.pic | rtrace -ab 5 -oodLpnsm -h -x 1 -i   someOct.oct 

The "|" is typed by pressing shift and backshash on a US keyboard.  If you
are unfamiliar with pipes check out these links for an explanation:

Hi there
I'm trying this line from a previous thread for info about rays in an image
ximage someRendering.pic rtrace -ab 5 -oodLpnsm -h -x 1 -i   someOct.oct

I get the image displayed but these lines appear
./ximage: rtrace : bad picture format
./ximage: -ab : cannot open picture file
./ximage: 5 : cannot open picture file
./ximage: -oodLpnsm : cannot open picture file
./ximage: -h : cannot open picture file
./ximage: -x : cannot open picture file
./ximage: 1 : cannot open picture file
./ximage: -i : cannot open picture file
./ximage: testroom.oct : bad picture format

left clicking and dragging on the image makes a rectangle selection but
nothing happens right clicking I get just the origin and direction outputted

I know I must be doing something simple, wrong

Thanks for any help

Tarik
