[Radiance-general] x11meta issue

Sat Oct 3 17:06:19 PDT 2015

Hi Ruggiero,

Do you have dot (".") in your RAYPATH?  If not, then xform won't look in your current directory(!) for named input files.  I would add "." to the beginning of RAYPATH if it isn't there already.

I don't know why you wouldn't be getting an oblique view from objline.  It seems to generate all 4 views when I run it.

On my entire storage device, I only see this file in a couple of places, and they’re all locations where I had really old archived installations of Radiance (built with your “makeall” script). This makes me think this is a Radiance thing that somehow never got included in the mirror...

Sorry about that, I haven’t had a chance to sort that one out yet. Used to be, no one ever used x11meta but it appears lots of people are starting to pick up Axel’s tutorial which includes the use of that tool, so I guess I’d better get this sorted!
