UNIT 4: TESSELLATIONS

TESSELLATIONS

A tessellation, is  a repeating pattern of polygons that covers a plane with no gaps or overlaps. 

What kind of tessellations can you make out of regular polygons? 

TRY Tessellation Creator.   

This is the video we saw in class:

WHAT IS TESSELLATION? 

If we look around us we can see that the shapes, triangles, squares, hexagons, are related to each other to occupy a large space; that is to say, they have interior lines that distribute and order the shapes. These are their structures that provide order and proportion. These structures are called tessellations. 

A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries.

Structures can be:

• Regular: the elements that compose it are regular and follow a regular order. Symmetrical or radial organisations tend to predominate.

  Irregular: they do not have a regular order and their elements are irregular. They are complex structures.

  
            

The shapes are related in space by structures that we call Tesselations. Thanks to this organisation, we can create modules that repeat until we fill the whole area.

The movements we can make in space are:

And these are some other ideas for your project:

UNIT 2: TANGENTS

TANGENCY

WHAT IS A TANGENT? 

A tangent to a circle is a straight line that touches the circle at one point.

ACTIVITY/TAREA 1: ONE POINT LINEAR PERSPECTIVE

ACTIVITY: "ONE POINT LINEAR 

PERSPECTIVE"

Following the information and vídeos you have here, 

do your own drawing.

Do not forget to be as original and creative as you can. 

HISTORY OF LINEAR PERSPECTIVE

As you already know we live in a three-dimensional world:  

1. Height, 2. Length 3.Depth

We can change or viewpoint, trasnforming the way we see things. That way objects seem to be smaller of bigger depending whether we are close or far away from them. The same way objects might seem to vanish or disappear when we move around them or we move away from them. Light also plays a very interesting role in the way we perceive objects. 

3D OPTICAL ILLUSION

These are examples for our NEXT ACTIVITY (one point linear perspective): 

 

 

3D STREET ART: A QUESTION OF PERSPECTIVE

The wife of 15th-century Italian artist Paolo Uccello used to beg him to come to bed. She was fed up of him staying up all night drawing objects with the new method of 3D illusion – or as it was called at the time, "perspective". He still wouldn't come to bed. "This perspective is such a sweet thing," he said.

PERSPECTIVE IN FILMS

WHO DO YOU CHOOSE TO BE?

This video, done by the film director: Juan Manuel Cotelo, was done in CoronaVirus times, but it can certainly be apply to our daily life. Food for though. Are you acting villain or hero? 

Here is a presentation with images from films that use one point linear perspectives, like Star Wars or Harry Potter. 

PERSPECTIVE IN FILMS

OVOTANGRAM

 The construction of the OVOTANGRAM 

The ovoid tangram, egg tangram or also known as ovotangram is a tangram with a funny shape and with more pieces that curiously allows to build figures that resemble some types of birds.

HERE you can see how the ovoid is represented and the game is constructed.

OP ART

 This term we will be searching and analyzing how to create a few optical illusions. We will get started by doing our own original pieces of Op Art. Here is t more information about it, about Bridget Riley's works and a few activities. 

NEXT TASK: "OP ART" using parallel lines and tangent circles

MATERIALS: Set square rulers and a black feltpen
