[Radiance-general] lighting per pixel or per face?

[Fitzsimmons, Rob]

 Is that an imported/converted cylinder or a native Radiance cylinder?
If the former, try increasing the poly resolution before exporting
I use obj2mesh and it smooths pretty well

I believe its per pixel computation

Hi there!
 
I am wondering whether radiance make per pixel computations for lighting
or it just make computations per face (triangle/surface)
 
I have tried to illuminate a cylinder with a light probe. 
If you look at resulted image, you can distinguish the faces/divisions
from which cylinder model is made of.
 
You can see the result in jpg here

The problem that I tried to explain in the previous paragraph is there
where red arrows show. (I added arrows manually)
 
Is there a way to make the lighting smoother in area  where red arrows
show? 
 
I used this to take the result:
rpict -x 600 -y 600 -t 30 -ab 2 -ar 10000 -aa 1.0 -ad 2048 -as 1024 -st
0 -sj 1 -lw 0 -lr 8 -vf camera.vp thermos12_base.oct > res.hdr
 
Thanks,
Despina
