Announcements

December 10, 2003 

• The final examination is scheduled for Saturday, December 13, from 2:00pm - 5:00pm in GEO 2.102.
  
 

• Graded Midterm exams (I and II) are available in Professor Bajaj's office.  Check with the administrative associate, Rand Martin, when Professor Bajaj is away from his office.
  
 

• The Practice Final with solutions has been posted under the Exams section.  The questions only cover some of the later topics in the course, so when you review, you should also consult the Practice Midterm and the notes and Projects throughout the course.
  
 

• A brief study guide of important topics for the Final is available here.
  
 

• The solutions to Midterm 2 have been posted under the "Exams" section.
  
 

• The solutions to Project 4 have been posted under the "Projects" section.
  

November 25, 2003 

• Both lectures next week (Dec 2 and Dec 4) will take place in the ACES Graphics Lab instead of in the normal classroom.  The ACES Graphics Lab is located in ACES 2.102, which is accessible using the double wooden doors right across from ACES's double elevators.  If you walk into ACES from the north entrance and go straight ahead down the corridor, it will be the double wooden doors on your left.  There is a lock on the door, but someone should answer if you knock.
  
 

• Because of the no-class days policy, the absolute, final deadline for Project 4 is 11:59pm, Sat, Dec 6.  This is the Saturday right after the last day of classes.  We cannot accept any projects after this date because of the university-wide policy.  Send email to the course staff if you expect to have any problems with this due date.
  
 

• To avoid clutter, the recent announcements for Project 4 are available here.
  

November 17, 2003 

• Solutions to the written parts of Projects 2 and 3 have been posted under the Projects section.
  
 

• Two required features have been added to Project 4: a) point light sources and b) at least two new object types in addition to sphere.  These changes have been marked with the notification ***NEW***.
  
 

• An error was discovered in the Discussion Section 4 notes.  The formula for the cross product:
  
  A cross B = ([Ax * Bz - Az * Bx], [Az * By - Ay * Bz], [Ax * By - Ay * Bx])
  
  ...is incorrect.  The following is the corrected version:
  
  A cross B = ([Ay * Bz - Az * By], [Az * Bx - Ax * Bz], [Ax * By - Ay * Bx])
  
  A new diff file (diff2.txt) has been posted that includes this change, along with a few other changess since the last diff.  The link to the notes points to the most recent version, so you do not need to apply the diff's if you use the latest link.
  

November 12, 2003 

• The Discussion Section 4 notes have been posted here.  A few changes have been made to the notes since the Discussion Section, and these changes are catalogued in this diff file (the diff file lists all lines that were changed in the HTML source for the notes.  This should give you a general idea of where the actual changes are in the printed version).
  

November 8, 2003

• Discussion Section 4 will be held Wenesday, November 12, from 2:30pm - 4:00pm in Taylor 3.144.  Please note that the room has changed.  To get to Taylor 3.144, go up one floor from the ground floor of Taylor.  The room is near the east end of the corridor.
  
 

• The solutions to Midterm 1 have been posted under the "Exams" section.

November 4, 2003

• The two polyhedra files, dragon.off and nface.off, have been removed from Project 3.  You do not have to include these files in your program, and if your algorithm does not support them, you should remove them from the list of files your program cycles through.  The files you still need to support are: cube, icosahedron, and unitPyramid.  If your code does handle the meshes that were removed, you may include them for extra credit.
  
 

• Two changes were made to the Discussion Section 3 notes.  Under the section: "Overview of Implementing the Catmull-Clark Scheme", under Step 4, a reference to "vertex rule" was replaced with "edge rule."  For the last diagram in the notes, the label "Control point from Iteration j" in the legend was changed to "Control point from Vertex Rule."
  
 

• After tallying the results of the Poll, we have decided that the Final will be held as scheduled on the syllabus.
