Hi
For creating animation viewfiles such as the massive anim.vf used in Paul
Debevec's Rendering with Natural Light, is there a simple or easy way to come
up with appropriate frame viewpoints and directions for say moving through a
room and looking at different objects in the room? Or should I just stop being
lazy and try work out some nice views?!

I use rview to do it...
Start with you initial view, then use a series of move, pivot, aim commands
to go to another view
Then set that view.
v keys.vf -t 2
move, aim, pivot to another view
v keys.vf -t 3
the -t indicates how many seconds after the previous view
You end up with a keys.vf with several keyframes
create a text file called key.fmt
rview -vtv -vp ${px} ${py} ${pz} -vd ${dx} ${dy} ${dz} -vu 0 0 1 \
-vh ${vh} -vv ${vv} -vo 0 -va 0 -vs 0 -vl 0 -t ${t}
generate a key.cal file
rcalc -i key.fmt -e '$1=recno;$2=px;$3=py;$4=pz;$5=dx;$6=dy;$7=dz; \
$8=vh;$9=vv;$10=t' keys.vf | tabfunc Px Py Pz Dx Dy Dz H V T > key.cal
then add up all your -t numbers from keys.vf and muliply that by your frames
per second (I use an excel spreadsheet)
In this case, I'm animating 15 fps for 36 seconds
cnt 540 | rcalc -o key.fmt -f key.cal -f spline.cal -e 't=$1/15' -e \
'px=s(Px);py=s(Py);pz=s(Pz);dx=s(Dx);dy=s(Dy);dz=s(Dz);vh=s(H);vv=s(V)' >
anim.vf
If I were to animate at 30 fps,
it'd be
cnt 1080 | rcalc -o key.fmt -f key.cal -f spline.cal -e 't=$1/30' -e \
'px=s(Px);py=s(Py);pz=s(Pz);dx=s(Dx);dy=s(Dy);dz=s(Dz);vh=s(H);vv=s(V)' >
anim.vf
Use anim.vf in a ranimate file
Good luck!

Sorry, I left out the -vo 0 and -va 0
key.fmt should be (all on one line)
rview -vtv -vp \{px\} {py} \{pz\} \-vd {dx} \{dy\} {dz} -vu 0 0 1 -vh \{vh\}
\-vv {vv} -vo 0 -va 0 -vs 0 -vl 0 -t ${t}
the key.cal should look something like this
Px(x):select(x,-64.7853,-50.0121,-9.8244,10.185,10.185,11,
18.1985,67.4101,49.2971,33.793);
Py(x):select(x,-33.2456,4.54799,10.7872,10.5673,10.5673,
16.8863,15.6925,16.8799,-1.30873,-7.31969);
Pz(x):select(x,12,13,9.5,9.5,9.5,9.5,10.5478,10.5,9.59094,

Hi Rob
Thanks very much for your help.
When I get to

'px=s(Px);py=s(Py);pz=s(Pz);dx=s(Dx);dy=s(dy);dz=s(Dz);vh=s(H);vv=s(V)'

I get this error

Do you know what the problem is?

I think that's what you had before because I have the same error. I have my
keys.vf file but where does that come into when processing the frames because
in all the commands you've written below, none of them use keys.vf. Or am I
just being stupid and missing a simple point here?
