Deadline: June 23rd (Thu) at 15:00pm

---

Before Doing Assignment

If you have not done the task00, do it first to set up the C++ graphics development environment.

Follow this document to submit the assignment, In a nutshell, before doing the assignment,

• make sure you synchronized the main branch of your local repository to that of remote repository.
• make sure you created branch task08 from main branch.
• make sure you are currently in the task08 branch (use git branch -a command).

Now you are ready to go!

Problem 1

1. Build the code using cmake
2. Run the code
3. Take a screenshot image (looks like image at the top)
4. Save the screenshot image overwriting task08/problem1.png

By the way, the view navigation of this program works as

• rotation: alt+left mouse button,
• translation: shift+left mouse button
• scale: mouse wheel

Problem 2

Write code at line #129 to implement Laplacian mesh deformation.

Save the screenshot image overwriting task08/problem2.png

Look at Eigen's reference if you are interested in sparse linear solver:

• Sparse linear algebra

After Doing the Assignment

After modify the code, push the code and submit a pull request.
