So, this is representative of what I think he wants - minus the closed loops
inside the "knot".
That can probably be fixed with a function pigment color map, or just difference
the object or a surrogate from the plane.
plane {y, 0
texture {
pigment {wood
warp {
black_hole <0.5, 0, 0>, 10
falloff 7
strength -5.0
}
color_map {
[0.0 Blue]
[0.2 Blue]
[0.2 rgbt 1]
[1.0 rgbt 1]
}
}
}
texture {
pigment {wood rotate y*90
warp {
black_hole <0, 0, 0.5>, 10
falloff 7
strength -5.0
}
color_map {
[0.0 Red]
[0.2 Red]
[0.2 rgbt 1]
[1.0 rgbt 1]
}
}
}
}
