Prelab 3: Etch-a-Sketch

Due: Thursday, September 17th in class

 

In this prelab you'll design a picture that you'll be generating with a program in the Thursday lab 3.

Part 1 - Drawn Out

We're now ready to get into the media portion of the course.  You'll be creating an image using Python and a collection of functions called in the graphics.py module.  For now, don't worry about what this means or how it is done; all you'll be doing for the prelab is designing an image you'd like to create.    Below are a few examples of some past projects.

      

       

Obviously, the idea is not to just copy one of those.  Obviously. 

But these should give you some ideas of what you might be able to do.  Contrary to these examples, clouds are not required elements of your composition.  You could do a cityscape, a picture of some part of campus, a scene of a bear fighting a shark, a recreation of a famous painting, or anything else so long as it has a level of complexity comparable to the pictures above.

As for what you'll be able to actually do with you programs, you'll have the ability to draw straight lines of any width.  You'll be able to make circles, squares, rectangles and ellipses, and all of these can be either filled or empty.  Everything you draw can have any color you want. 

On a regular-sized blank piece of graph paper, draw a scene you'd like to create.  I don't care what you use to make your sketch, so long as it is not computer-based.  Markers, colored pencils, pens, or any such media are fine.  The expectation is not that you are a skilled artist, but do put in some effort to make something that looks nice.

Part 3 - Submitting

No uploading, just hand in a hard copy of your design to me in class on Thursday.
