## OP ART (13th-24th APRIL)

13 04 2020

Dear Students

How are you doing? I hope you are ok!

These two next weeks we are working with the OP ART! We are going to learn how to create different grids and shapes.

SOME HISTORY:

Op-art, also known as optical art, is used to describe some paintings and other works of art which use optical illusions.

Op art works are abstract, with many of the better known pieces made in only black and white. When the viewer looks at them, the impression is given of movement, hidden images, flashing and vibration, patterns, or alternatively, of swelling or warping.

A true Op Art piece “teases” the eye. Straight lines may appear curved, lines wriggle, flat areas undulate. The eye is tricked into seeing things which are not so. Areas may appear to be flattened or stretched. The eye may often be unable to focus when viewing an Op Art piece.

In the mid-20th century, artists such as Victor Vasarely, Bridget Riley and M.C. Escher experimented with Optical Art. Escher’s work, although not abstract, deals extensively with various forms of visual tricks and paradoxes.

SKETCHING:

Experiment with perspective; use grids, shapes, and lines to create patterns and illusions.

• Your piece should be designed in black & white on a graph paper. Each square mesures aproximadamente 10×10 cms. Use a black felt tip pen.
• Sketch at least 4 different ideas. You have to copy four of the grids you have got. There are 8 of them. Choose only four. If you have a hard time starting the sketches - you can follow the steps.

## One point perspective:

It  is a type of linear perspective exactly the same as parallel perspective it combines a mathematical systems along with a vanishing point in order to represent three-dimensional objects on a two dimensional surface. This is achieved by intersecting the lines that are draw either horizontally or vertically. From the vanishing point the lines radiate outwards giving the illusion the viewer is looking into the picture and can sense the depth of distance. Therefore when typically drawing railways,roads,buildings or halls using one point perspective it gives the illusion that’s the object is directly facing the viewer, and gives a sense of depth.

## Two point Perspective:

It uses exactly the same method as One point Perspective does however, T-PP has two vanishing points usually 90 degrees apart on the horizon and all lines radiate from those points.

And now we are going to practice how to draw with perspective…. You can choose bewteen 1 or 2 points… Let’s go outside of the classroom to draw the school building!

## HILORAMAS

26 11 2012

Many spectacular things with simple things that we have to our reach can actually be achieved!
What is needed is imagination and dedication.

Visit this link: This project uses the pen to make String Art between the blue dots that you can drag around the screen. http://scratch.mit.edu/projects/Paddle2See/89023

The hilorama is a technique that is characterized by the use of threads of colors, string or tensioned wires that were wrapped around a set of nails to form geometric figures, abstract or other types of representations. This procedure is usually carried out on a basis of  wood, and any idea imaginable can be reproduced.

Generally, although the figures are formed by straight lines, different angles and positions in which the threads intersect may give the appearance of the Bézier curves. Other forms of this string art include Spirelli style, normally used for the realization of cards and scrapbooks, among other things.

The art of the hilorama stems from so-called “letters of Boole”, invented by Mary Everest Boole at the end of the 19th century to make the theory of math more understandable for children. Mary used these letters to help his students learn geometry angles and spaces with them. This was popularized as a decorative art during the 1960s through books and learning kits.

El hilorama es una técnica que se caracteriza por la utilización de hilos de colores, cuerdas o alambres tensados que se enrollan alrededor de un conjunto de clavos para formar figuras geométricas, abstractas u otros tipos de representaciones. Este procedimiento se suele llevar a cabo sobre una base de madera pintada o tapizada, y con él se puede reproducir cualquier idea imaginable.

Generalmente, aunque las figuras están formadas por líneas rectas, los diferentes ángulos y posiciones en el que los hilos se cruzan pueden dar la apariencia de las Curvas de Bézier. Otras formas de este arte de cuerda incluyen el estilo Spirelli, utilizado normalmente para la realización de tarjetas y álbumes de recortes, entre otras cosas.

El arte del hilorama tiene su origen en las llamadas “cartas de Boole”, inventadas por Mary Everest Boole al final del siglo XIX para hacer la teoría de las matemáticas más comprensibles para los niños. Mary utilizó estas cartas para ayudar con ellas a sus alumnos a aprender la geometría de los ángulos y espacios. Esto se popularizó como un arte decorativo durante la década de 1960 mediante kits de aprendizaje y libros.

### What You Need:

• compass
• protractor
• paper
• pencil
• ruler
• pen and ink
• colored markers

### What You Do in the first picture:

1. Find the center of the page and put the pointed end of the compass there
2. Draw the largest circle the paper will allow with the compass.
3. Draw several circles inside the big circle.
4. Create distortions by drawing at least three circles close together. Have at least three distortions in the picture.
5. Use the protractor to mark off each half and whole degree. Mark all the way around the circle by turning the protractor upside down.
6. Draw lines using pencil and ruler from the center through the mark and out to the last circle.
7. Fill in the blocks created with pen and ink in checker board fashion.
8. Color in white sections in a contrasting color, or leave white.

### What You Do in the second picture:

1.  Draw parallel lines in horizontal position with the same space between them.

2. Draw parallel lines in vertical position and change the space between them by diminishing it and, after a while, increase the empty space.

3. Fill in the blocks with black felt pen.

## DRAWING PARALLELS LINES USING SET SQUARES
