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
