Title: Granny Knot Covered by 3D Fractal
Post by: Alon Nahary on November 08, 2017, 10:53:36 PM
Rendered by my Julia3D software, ray tracing mode, three minutes a frame. The basic shape is Granny Knot. It is covered by a combination of other fractals.

The Granny Knot parametric function is taken from Paul Bourke page: http://paulbourke.net/geometry/knots/

x = -22 cos(u) - 128 sin(u) - 44 cos(3 u) - 78 sin(3 u)
y = -10 cos(2 u) - 27 sin(2 u) + 38 cos(4 u) + 46 sin(4 u)
z = 70 cos(3 u) - 40 sin(3 u)
where 0 < u < 2 pi

I really enjoyed it.   I love  the roughnes of the circles like  they are made of clay, smoothly spiraling on/and in the water, absolutely great work.
