#include "colors.inc"

camera {location <95,85,-1000> look_at <95,85,0> angle 25}
light_source {<500, -700, -150> White}
object {torus {100, 10 rotate 90*z scale <18,1,1> translate <45,85,0>}
texture {T_Chrome_5D}}

The above code produces two lines of artifacts across the torus for me.
Anyone else see this problem and better yet do you know how I can fix it?

Thanks,
Carl

The math necessary for rendering a torus tends to be pretty sensitive and
can create artifacts sometimes. To switch to a different method of
intersection calculation, use the keyword "sturm" in your torus. This should
be more accurate and in your case I believe it fixes the problem.
