What's the difference between four-way continuous and two-way continuous?

There are three continuous bone methods: vertical bone, scattered bone and corrugated bone.

The common arrangements of quadrilateral continuity are trapezoidal continuity, rhombic continuity and quadric (square) continuity. Printed cloth, wallpaper and other patterns often use this organic law.

Second, the difference in definition:

Two-way continuity is a pattern formed by a unit pattern (one pattern or two or three patterns combined into a unit pattern), which is repeatedly continuous in the up and down or left and right directions.

Quadrilateral continuity is a pattern form composed of one pattern or several patterns as a unit, which is continuous and extends to the surrounding repeatedly.

Bidirectional continuity:

Quadrilateral continuity:

Third, the differences in organizational forms:

Two-way continuous pattern can be divided into three types: dispersed two-way continuous pattern, wavy two-way continuous pattern, broken-line two-way continuous pattern, geometrically linked two-way continuous pattern and heald table two-way continuous pattern.

According to the change of basic bone type, the square continuous pattern includes scattered square continuous patterns,
