Description
The assignment will focus on the concept of Chaikin, Bézier curve algorithm. Given a headshot
photo of an individual (e.g. the headshot of Ed Sheeran), generate the cartoon version of the
photo by sketching it using Chaikin or Bézier curves.
Skeleton code has been provided to guide you along the way. The places that you will be
required to implement has been marked with a TODO.
I have provided you with a simple Vertex class that allows you to specify the x and y values of a
point. You will utilize this class for modeling the control points of your sketch.
**Note: the C++ vector class is the equivalent to a list in most other languages. You may use the
push_back(Object o) function of the vector class to hold your set of points.
You will complete the following functions for the assignment:
1) generate_points : a function that generates takes in a set of control points for your
Chaikin or Bézier curve algorithm and returns the new set of control points
parameters: vector
returns: vector
2) draw_curve : calls generate_points to generate the control points using the Chaikin or
Bézier curve algorithm and forms a curve by connecting the points with lines
parameters: vector
returns: none
The parameter n_iter refers to the number of iterations to run the Chaikin or Bézier algorithm.
Recall that each time the algorithm is ran, you will obtain a set of new points.
Submission:
You will submit the following to Bright Space
1) “assignment1.cpp”
2) Your sketch in JPEG, JPG, or PNG: results.{jpeg, jpg, png}
3) The photo your sketch was based on in JPEG, JPG or PNG: photo.{jpeg, jpg, png}
Grading:
I will be compiling the assignment using the following command:
gcc -o assignment1 assignment1.cpp -std=c++14 -lGL -lGLU -lglut
Your code must compile for me to assign points!
Your assignment will be graded on:
1) 80% the correctness of your implementation of Bézier’s algorithm
2) 20% effort placed recreating the subject via your sketch
e.g. a simple happy face does not do Ed Sheeran justice
Late Policy:
For each day the assignment is late, 50% of its worth will be deducted, e.g. 100% on time, 50%
1 day late, 25% 2 days late, etc.
