Computer Graphics (fall,2009): home

12/4 Bug of proj3-2 is fixed. (showing the position of control points at the incorrect locations.)
11/27 Project #3 is posted. [Due: 15 Dec. 11:59pm]
11/27 viewer.c is updated. In the old version, only positive ids are used for picking, but now zero id is also used. (Not a big deal, but easier to handle arrays.)
11/6 More mistakes. I wrote all the samples using freeglut as the glut library. You may have a compilation error if you try compiling them with GLUT32. To fix it, just put the line "#include <GL/glut.h>" below all the other header files. (e.g., <stdlib.h>)
Also, some sample programs doesn't show anything since I mistakenly call glutSwapBuffers while I just initialized single buffer. (polyoffset.c and hud.c had this bug.) Now I fixed them. (at leat I believe so...) Let me know if you have any problem with the samples.
11/6 There was an error in the executable proj2_xp32.exe. (I compiled using "freeglut" not "GLUT for Win32" by mistake.) Please let me know if you still have any problem.
11/1 Project #2 is posted. [Due: 24 Nov. 11:59pm]
10/22 Slide #6 has been updated.
10/12 Late submission of project #1: You may get at most 50% of your score, but it's still better than submitting nothing. So go ahead and submit your project as soon as possible. [Late submission due: 11:59pm 16 Oct.]
10/6 Any EXE file attached in the e-mail cannot be delievered since it's considered as a virus. You can change the file extension to, say, ZIP, or just send the source file.
9/18 Project #1 is posted. (due: 6 Oct. 11:59pm)
9/17 GLUT sample codes are uploaded in the materials page.
You may notice that a sample named postredisplay.c is posted which was not presented in the lecture today. This sample is to show you how to use the function glutPostRedisplay. When you press the space bar, the color of the rectangle will be switched between red and white. We expect the color changes immediately after we press the space bar, and this is why we call the function at the end of keyboard callback. Without this, the color changes only when the window needs to be refreshed. (so that the display callback is called) To see the effect, try commenting out the line calling glutPostRedisplay and see how it works. Without the call, you have to force the display callback is called by, for example, covering the window with another window and then removing it away.
9/16 To fix the error (on Windows XP)
error C2381: 'exit' : redefinition; __declspec(noreturn) differs [WHERE_GLUT_IS_LOCATED]\gl\glut.h(146) : see declaration of 'exit'
try removing the include sentence in the source.
//#include <stdlib.h>
9/16 교과서설문의 "기초설문조사" 참여도가 너무 저조하오니 많이 참여해주시기 바랍니다.
9/10 Lecture slides can be found in either schedule or materials page.
9/9 howto-win32.txt shows step-by-step procedure to compile an OpenGL sample on Windows XP. (It's quite straightforward to apply this to other Windows systems.)
9/8 The office hours has been moved to 4~5pm on Wednesday permanently.
9/2 Welcome. In this course, `passcode' will be used to post your scores for your privacy. Please send your own passcode (composed of 4 alpha-numeric characters) to me as soon as possible. In case of conflicts, please send at least three candidates. For example, your e-mail may look as follows:
name: Minho Kim
id: 20090000
passcodes: (1)1a2b (2)2b3c (3)abcd
