FS#223 - Artifacts in thin torus
Thin tori exhibit artifacts in 3.7.0 RC3 when the camera is placed inside the torus close to its “center plane”, as can be demonstrated with the following scene:
camera { location <0.0, 0.0, -0.5> direction 1.5*z right x*image_width/image_height look_at <0.0, 0.0, 0.0> angle 1 } light_source { <-30, 30, -30> color rgb 1 } torus { 1, 0.001 texture { pigment { color red 1 } } }

artifacts not present with the
"sturm" keyword
Tested with 3.6 : also present (a bit different, but can be due to AA setting and s/rgb)
Adding "sturm" to the torus remove the noise, for 36 and 37RC3+. (+H1025 +W1025 +A0.01)
