What are vector graphics?
|
Vector graphics are used in all kinds of media; from advertising, animations, product design and fine art. Vector images are created by combining geometric shapes, lines, and curves that are contructed using mathematic equations, as opposed to the 'raster' format (used in apps such as MS paint) where individual pixels are used. As a result, you can zoom into vector images to any scale, without the pixelation that occurs with raster graphics. This is why vector graphics are used for billboard signs etc.
Teaching vector graphics in primary schools As vector graphics are now widely used across many industries, it makes sense for children to begin learning these skills in primary school.
The new DfE-funded NCCE / Teach Computing scheme incorperates a vector graphics unit in Year 5. I have built upon this planning, creating new resources that enable children to learn vector graphics in more depth. To introduce the topic of vectors graphics to children, I use the two videos to the right. The Kurzgesagt Youtube channel uses exlusively vector graphics in its videos; you'll notice the unique visual style and colour pallet. |

Vector software
Basic vector images can be created using Google Slides and Google Drawings, but I have more recently been using the free, cloud-based 'Vectr' software with children (vectr.com). It is a little more complicated than Google Slides, but has many more features. Below is a gallery of images made by my Year 5 and 6 pupils using Vectr software. Please note, the images below have been exported as .png files so will pixilate if you zoom in.

Vector graphics and 3D modeling software
The workflow of producing a 2D vector images has parallells to the techniques used in industry-standard CAD software such as Fusion 360, Autocad, Solidwords, Sketchup, and others.
In addition, vector graphics can been imported into Tinkercad and used to create 3D shapes. The lighthouse model model below was created by drawing a curved shape in Vectr, then importing this into Tinkercad.
