the exercise was to take the ballroll anim from helpfile and roll it in a
circle
to test my ability to use pov.

num rolls = 3.7239

I spaced-out on the angle for the numrolls. 90-30 = 60

aas-sin(pi/2,deg2rad(60),4.3) = 3.7239

rolls = 4.0;

vlength = 4.61888
#declare A_point = vrotate(vaxis_rotate(z,A,-30),360*clock*y)*4.61888;

so there is an even num rolls per loop

At that size, you could remove the texture on that torus, it will make the file 
somewaht smaler.

hey Alain.
Debug_Message this:

clamp(0.65 - 0.75,0.0,0.25) = 0.15

and should be 0.0

by my macro logic:
#macro _clamp(nn,n,m)
   #local result = nn;
   #if (nn < n) #local result = n;
   #end
   #if (nn > m) #local result = m;
   #end
   result
#end


took awhile of messin with stuff that didnt need messin with cause I assumed
clamp() would work.

5 bits per pixel setting on file save was the answer for a little larger
image. The texture was useless and ugly
