TENTURA

The essence of Tentura’s nature is that it breaks the connection between the body and soul of every living being under its influence. The subject becomes bound to a global variable, which is calculated and controlled by the Tentura itself. To understand this, you can use the metaphor of virtual reality. A person starts a computer game and takes control of a character. The character acts under the influence of the player's will. In this case, the player personifies the character in its entirety - the soul (various game-mechanical characteristics) and the body (the image on the screen). The rules of the game symbolize the material world with its rigidly defined laws. Imagine that, at some point, a third-party program turns off the player's means of input and begins to control the character itself, calculating their next actions according to some internal algorithm. In this case, the events taking place with the character are no longer determined by the will of the player or the rules of the game itself. Instead, this control comes via a ready-made plot which was previously written by someone or generated by the program itself. This is the meaning of Tentura, with the amendment that the object of its control is reality.

Tentura is divided in two or three different zones which control the behavior of the relevant strings or wires there. When the string leaves the zone it began in, it retains its color but its behavior changes. A string can stop when it changes zones, and if not, its direction shall change. The starting positions of the strings have two different basic distribution rules - fully or partially distributed on the image. Partial distributions can be circle, ring, triangle, square, pentagon or lines, which can be shifted, rotated etc. Fully distributed images can include cracks or not:

Partial distributions have different shapes and can be masked by the edges of image (most wires not leave the image) or not masked (every wire can leave the image):

These smaller zones of Tentura are drawn with various types of shapes - lines, rings, triangles, squares, pentagons, hexagons and with regilar, partial or spiral variations. Here are several of them:

Every piece is animated, please look closer to see more details...

This artwork is based on a noised vector field (also known as a flow field), which include 2 variations and 2 modifications:

After that, one of six shapes are drawn on top of the vector field, with the "brush" effect (where field direction is changed with direction of the brush movement):

These shapes also have variations in that, they can be shifted from center, rotated or deformed, and can be partial or spiral:

These three zones on the vector field are used to control the behavior of the strings or wires. They provide not only direction, but also color choice, and random turns and stops. String or wire distributions are also different and can be one of these 6 types:

Distributions, can also vary in that they can be rotated, shifted, include a cutout, nave noise, and include any combination of these modifications:

Fully distributed wires can include "cracks" made by several octaves of noise, Other distributions can be "cut by edges" to prevent most wires from crossing the edges. All code has been written on typescript, and bundled to a single javascript file with a total size of approximately 5.5 kilobytes. Special thanks to . They supported me and sometimes pushed me in the right direction while creating this work.
