[Radiance-general] creating a good animation view file

[Fitzsimmons, Rob]

Tarik
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,
10.1661);
Dx(x):select(x,0.844167,0.897459,0.970004,0.839548,-0.245395,
-0.845484,-0.990763,-0.913368,0.956497,0.800968);
Dy(x):select(x,0.500454,0.404528,0.226646,-0.54133,-0.968567,
-0.531364,-0.0175715,0.0300529,0.28554,0.587995);
Dz(x):select(x,-0.192164,-0.17585,-0.0878825,-0.046062,
-0.0407428,-0.0529912,-0.134459,-0.406025,-0.0598303,-0.112747);
H(x):select(x,50,50,50,50,50,50,50,50,50,50);
V(x):select(x,50,50,50,50,50,50,50,50,50,50);
T(x):select(x,1,3,6,3,2,2,2,5,3,5);

Hi Rob
Thanks very much for your help.
When I get to
./cnt 435 | ./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)'
>
animate.vf

I get this error

key.cal, line 1:
Px(x):select(1,);
               ^ unexpected character

here is my key.cal as you specified
more key.cal
Px(x):select(1,);
Py(x):select(1,);
Pz(x):select(1,);
Dx(x):select(1,);
Dy(x):select(1,);
Dz(x):select(1,);
H(x):select(1,);
V(x):select(1,);
T(x):select(1,);



Do you know what the problem is?

Thanks

Tarik
