Project 11: 3D Scenes

The assignment this week has two parts. First, demonstrate use of the 3D turtle and build some interesting 3D shapes. Second, pick one significant extension of the system and design and implement your own solution. The list of extensions given below is not all-inclusive, and you should feel free to pick your own. The key is to demonstrate how you can define a task, design a solution, and implement the solution so the computer can complete the task. Efficient and elegant solutions are the optimal outcome.


  1. Make at least four new 3D shape classes, like a box or a house. Use strings, just like you did for the square and triangle classes. You can use parameterized strings, which should make the task easier.

    An image with examples of all of your 3D shapes is required image 1. In this image, demo at least 2 different styles.

  2. Make a 3D scene that incorporates your shapes. Your scene can be abstract, artistic, or realistic. Try to maximize the complexity of the scene, while minimizing the amount of code you have to write. For this task, spend some time thinking about your design before you start to code. Talk about your design in your writeup. Note that complexity may not mean lots of objects. Having lots of small stuff will slow down the interactive viewing.

    Two images of your scene from different points of view are required images 2 and 3.

  3. Do something interesting within this context. Make sure you have a clear description of the task. Design a solution you think will work and then implement the solution. The difficulty of the task is not necessarily as important as following a structured process so you understand what the computer needs to do and how to do it. The design of your solution should be part of your writeup. Note: you can choose something from the list of extensions, if you would like. If you are wondering how we will grade it, then keep this is mind: we don't simply count the number of extensions you do. We look at the quality. If this task allows you to do something spectacular, then it may get you over the 26/30 mark.

    An image demonstrating your solution is required image 4.

Extension Examples

These are just examples, not necessarily recommendations. Please feel welcome and encouraged to design your own. A great extension genuinely interests you, pushes your understanding of CS, and inspires you to learn something new.

Hand-in and Report

  1. Put the python files you wrote on the Courses server in your private directory in a folder named Project11.
  2. Make a new wiki page for your assignment. Put the label cs151f18project11 on the page.

    In general, your report should follow the outline below.

    • Title includes your name and clearly describes the project.
    • Section headings are used to delineate distinct sections of the report.
    • Abstract identifies key lecture concepts (e.g. code structres, data types, and libraries) relevant to the project.
    • Abstract explains why key lecture concepts are important to achieving project goals.
    • Abstract identifies program output(s), giving context to the project tasks.
    • Solutions to tasks are described, focusing on how you used key lecture concepts to solve each task.
    • Required images/outputs are present and clearly labeled.
    • Reflection at the end of the report addresses how the lecture concepts mentioned in the abstract made this project possible. If you can think of a more elegant way to achieve the same results, please share!
    • Sources, imported libraries, and collaborators are cited, or a note is included indicating that none were referenced.
    • Don't forget to label your writeup so that it is easy for others to find. For this project, use cs151f18project11
