[Radiance-general] Ranimate / Mkillum issue

[Mark de la Fuente]

** Proprietary **

Group,

A couple of months ago I ran a series of simulations tracking the sun
across a space.  Since then I've gone back and tried to clean up and
improve the animations (for marketing purposes) only I've run into what
seems to be either a glitch or more likely a user error.  I'm using rad
and ranimate to automate the process.

My rif file looks like this...

EXPOSURE= 1
DETAIL= H
EYESEP= .225
INDIRECT= 2
materials= ./material/mat.rad
OCTREE= ./octree/lobby_a.oct
PENUMBRAS= T
PICTURE= ./images/lobby
QUALITY= H
RESOLUTION= 512
illum= ./scene/illums.rad
scene= ./scene/ground.rad ./scene/floor.rad ./scene/ceiling.rad
./scene/aluminum.rad
scene= ./scene/brick_xy.rad ./scene/brick_xz.rad ./scene/brick_yz.rad
./scene/brick_45.rad ./scene/brick_135.rad
scene= ./scene/glaz_exterior.rad ./scene/glaz_interior.rad
./scene/glass_door.rad ./scene/glaz_ripple.rad
scene= ./scene/wall.rad ./scene/rug.rad ./scene/wood.rad
./scene/wood_wall.rad
scene= ./scene/steel.rad ./scene/slats1.rad ./scene/slats2.rad
./scene/drapes.rad
UP= Z
VARIABILITY= H
view= vw1 -vf ./views/v1.vp
ZONE= I 0 17 0 19 0 9
render= -t 10

My ran file looks like this...

BASENAME= anim2/frame%03d
DIRECTORY= anim2
DISKSPACE= 500
START= 1
END= 53
host= localhost
INTERPOLATE= 0
MBLUR= 0
OVERSAMPLE= 3
RESOLUTION= 512
RSH= rsh
RTRACE= F
VIEWFILE= ./views/v1.vp
ANIMATE= genoctree_a.script
EXPOSURE= ./exposure/exp_a_interpolated_15.rad
RIF= lobby_a.rif

And my octree generator looks like this...

frame=$1
tmp=sun.rad
time=`ev "5.25+($frame/4)"`
gensky 3 21 $time +s -a 38.7 -o 90.5 -m 90 > $tmp
oconv -i ./octree/lobby_a1.oct -f $tmp sky.rad
rm $tmp

The problem is that the illum.dat files are not being updated for each
image and considering the fact that the sky is changing for each frame,
it seems to me like they should be.  Perhaps ranimate was really only
meant to deal with static lighting scenes with movable objects/camera
positions?

Any comments would be appreciated.

Thanks!
