• model of curve as spline
• reverse projecting of a curve segment
• texture mapping on cylinder surface
• bump mapping of elevation
• normal mapping of the cylinder surface

The waves-texture-based pattern. And the fiber-course-based paterrn for very close-up.

Only add to shader node editor menu

1. usage of configurator
2. tweaking main parameters
3. adding node tweaks

Nodes should (recursively) clean up their node trees to avoid bloating blend file.

construct procedural texture of twisted yarn:

• affects UV coordinates and can be applied recursively
• twists in any direction (S or Z)
• twists any number of strands (of equal thickness)
• twists with constant period of 1 (it can be customized by mangling input parameters)

• construct single knot of 2 arcs
• construct semi-loop of 2 knots
• align with neighbors

Knot types:

• knit-w
• knit-e
• purl-w
• purl-e

Combinations of half-loops:

• knit-w + knit-e
• purl-w + purl-e

Combinations of neighbors
{knot,purl} × {S, N, E, W} × {knot, purl}

In total: 32 combinations (of semi-loops)

• construct single knot
• align with neighbors

Knot types:

• weft-facing
• warp-facing

Neighbours: 4 (S, N, E, W)

In total: 32 = 2 * 16 combinations

Some nodes should be muteable and correctly relink default dataflow

Some smart disering algorythm to reduce number of colors so that they are arrangeable by stripes.
