Homework Homework
assignments are due by class time on the due date given (unless
otherwise specified). The preferred method of turn-in is via email to the TA. However, if you must
write out your answers by hand, homeworks may be turned in at class. Homework
assignments will be listed below as they are assigned. Homework

February 1 Due:
February 5, by class time (2:00 PM) Practicing
2D and 3D mathematics for graphics Answer
the following questions completely, on paper (turned in at class) or in an
electronic document (emailed to the TA). Please make sure that the final
answer to each question is clearly indicated. 1.

Vector v = (4, 1, 3). Find a vector orthogonal to v with a magnitude of 5. 6. How
far is point P = (1, 1, 1) from the plane passing through the points (0, 0,
0), (4, 3, 1), and (6, 2, 7)? 7.
Vector u = (7, 3, -2). Find two vectors that are orthogonal to u that are also orthogonal to each other. 8. Give
the parametric form of the line passing through the points P = (1, 2, 3) and
Q = (6, 5, -1). What point is 75% of the way from P to Q? 9. Find
a 2x2 matrix M that, when multiplied with a point P = (x, y), results in the
point (y, x). 10. Find
a 3x3 matrix N that, when multiplied with a point P = (x, y, z), results in
the point (2x, 3y, 4z). Homework
1: Assigned:
January 24 Due:
January 29, 11:59 PM Your
first openGL program Using
the code examples given to you as a starting point, write a simple openGL program.
The program should initially display a blank 500x500 pixel window with a
black background. When the user clicks the left mouse button the first time,
a small white square should appear at the location where the mouse was
clicked. Each subsequent left mouse click should also place a small white
square, and should connect the last point to the current point with a white
line segment (allowing the user to create a simple drawing consisting of
connected lines). You
should also provide a menu, accessed with a right mouse button click, that
allows the user to: a)
undo the previous line segment (you should allow the user to undo as many
segments as they want), b)
change the color (of the entire drawing) to red, green, blue, or white, and c)
clear the screen to start over. Turn
in your source code only by email to
the TA no later than 11:59 PM on Tuesday, January 29. |
