I'm trying to use mkillum to render my house.. and I'm having trouble
understanding it.=20
I have broken the elements into various Rad files=20
Nov15.rad - the sky description=20
house_mat_lit.rad=A0 - materials and lights used in the house=20
House6nw.rad - house geometry without window geometry=20
furniture.rad=A0 - the (duh) furniture=20
windows.rad - the window geometry=20
RwR chapter 1 suggests using a .rif with an "illum=3D" line=20
scene=3D nov15.rad=20
scene=3D house_mat_lit.rad=20
scene=3D house6nw.rad=20
scene=3D windows.rad=A0=A0 -- should this be here? or only as illum?=20
scene=3D furniture.rad=20
illum=3D windows.rad=20
# Options for mkillum=20
mkillum=3D -av 8 8 8 -ab 0=20
This is taking a long time to generate the .dat illum files - in fact I =
give
up after a while=20
I 'm thinking all I really need is the sky and the windows?=20
scene=3D nov15.rad=20
illum=3D windows.rad=20
This produces:
robfitzs% rad window.rif
oconv nov15.rad > window.oct
oconv -i window.oct windows.rad > window0.oct
mkillum window0.oct "<" windows.rad > il000924
oconv -f -i window.oct il000924 > window1.oct
rm -f il000924
this goes much faster, (creating 10 illum.dat files) but now how do I =
use
the illum data and render with all the rest of the house and furniture
without overwriting the previous simpler octree?
Could I add this to my rif?
octree=3D window1.oct
I also tried using mkillum manually ( for this, I combined the sky and
windows in 1 rad file) But I got an error=20
mkillum -ab 1 -ad 512 -as 256 -ar 16 < windowsSky.rad > winlit.rad=20
rtrace: fatal - command line error at '-ar'=20
mkillum: system - error reading from rtrace process=20
Does this make sense?=20
