Hi,
I have camera path declared as
time1 pos1 look1
time2 pos2 look2
timeN posN lookN

where pos is position of camera, and look is look_at in some time

now I want to use this varaibles to define location and look_at in current 
clock, how can I do this ?

-- 
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

  That looks a lot like a spline declaration.

  Make a spline for the location using the time and pos values and another
spline for the look_at using the same time values and the look values.
Then just call the spline with the time variable, and there you are.
  Besides, you get all kind of nice interpolations (besides linear one)
for free.

Just curious, but what's this data generated by? Is it CamPath or something like that
(Terragen path creator)?

All the best,

No, I thing that this will be quite comfortable way to controll camera, 
like :
0:00 under celing, looking straight +z
0:10 -||-, looking at floor
0:30 landed on flour, looking ahead
1:00 look at my model of i.e. cat
1:10 fly away

etc :)
