Radiance Tutorial problems (formerly "Installing Radiance in Ubuntu Problems")

Nick, you are almost there :wink:

rview's name changed to rvu. So call it again with

rvu -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test2.oct

Rpict gives out a picture, so the strange characters are what is happening if you write a picture to the terminal. Redirect output to a file and display it with ximage:

rpict -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test2.oct > image.hdr
ximage image.hdr

Or if you do not want to save the image but just display it, redirect the ouput to ximage using the pipe:

rpict -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test2.oct | ximage

I hope this helps a bit. Get used to input/output-redirection, which is described in all standard Linux tutorials. You should know the meaning of <, > and | in a unix-like system. Than introduce filters such as pfilt, ra_tiff, pcond. Than go on with modeling scenes, lights, materials.

Good luck!

Lars.
