## Preparation for next week
> **Computer-Controlled Cutting**  
> individual assignment:  
> cut something on the vinylcutter

  - vinylcutter
    - sand blast > Glass
        - Ref. [last year](https://fabacademy.org/2021/labs/kannai/students/natsuka-kamei/week3.html)
    - heat press > T-shirt

        - [Graduation](./images/T-shirts_grad.jpg)

> design, lasercut, and document a parametric construction kit

- Design
    - well Prepared -> your original
    - if not -> simple

## (Individual) Assignment

> model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final project,  
compress your images and videos,  
and post a description with your design files on your class page  

#### Have you answered these questions?

    -  [encoding](http://academy.cba.mit.edu/classes/computer_design/image.html)
```
//convert PNG to JPG:
% convert input.png output.jpg

//convert all PNGs to JPGs:
% mogrify -format jpg *.png

//convert SVG to PNG at 1000 DPI:
% convert -density 1000 -units PixelsPerInch input.svg output.png

//compress JPG to quality 50% width 1000:
% convert input.jpg -quality 50% -resize 1000 output.jpg

//compress all JPGs to quality 50% width 1000:
