Assignment
#1: 2D
Drawing in OpenGL
Date posted: September 12, 2007
Date due: September 26, 2007
Slides presented in class about this assignment available here.
Purpose
The purpose of
this programming assignment is to provide
- experience in using a
graphics package (OpenGL),
- an understanding of 2D
primitives and attributes,
- an understanding of
callback functions.
Task
You are to write
an application program using the OpenGL/GLUT
calls:
| Effect |
OpenGL commands needed |
| OpenGl Setup |
glutInit,
glutInitDisplayMode, glutInitWindowSize,
glutInitWindowPosition, glutCreateWindow, glutMainLoop,
glutDisplayFunc, glClearColor, glFlush or glSwapBuffers |
| Using different
primitives (lines, line-strip, line-loop,
triangles,
triangle-strip, triangle-fan, rectangle, quads, quad-strip, polygon) |
glBegin/glEnd,
glVertex, glRect
|
| Using different
attributes (line style, line width, fill
style, color) |
glLineStiple,
glLineWidth, glPolygonStiple, glColor, glEnable |
| Moving from one screen
to the next |
glutMouseFunc,
glutPostRedisplay |
Output Format:
What you "draw"
is up to you, but I would anticipate several different
screens that I can move between by pressing a mouse button, i.e.,
your image(s) should stay visible on the screen until either mouse
button is pressed and released. Your image(s) should also be
interesting!
NOTES:
- You are expected to use
EACH of the routines mentioned above.
- "Best Of" selections from
previous quarters are available for
your
viewing from the page http://www.cs.rit.edu/~ncs/Courses/570.shtml.
You'll need to copy the executable into your Unix account to run them.
I will select the "best" of your submittals to add to the web page and
for use
in future demonstrations.
A sample "Hello
World" type application for OpenGL can be found here.
Please feel free to use this as a
starting point.
What to submit
Please submit
all files necessary to build and run your program. This includes
source files, header files, project files, and Makefiles. In
addition, the submission should include a README that indicates the
platform on which your assignment is built, as well as notes on how to
build and run your project.
Platform specific OpenGL libraries should exist on each platform that
supports OpenGL. (In most cases, these libraries are supplied by
the manufacturer of the graphics card present on your system).
If you are planning on using the Suns for your project,
please make use of the following header.mak file to see the
proper libraries that need to be linked and the locations of those
libraries. (Note that if you use makemake or gmakemake, the contents of
this file will be incorporated into the Makefile produced).
NOTE:
OpenGL and GLUT are not installed correctly on the Sparc Based systems
(in ICL4)....Please use ICL1-3 (or Grad Lab) if you plan on using the
Suns!
All submission should be made using mycourses. Look for the
folder named "Assignment 1" in the dropbox area.
Assessment
Your overall
programming assignment grade will be based on the
following: demonstration of the use of the required routines, the
complexity (how interesting) of graphical output, internal
documentation, and program design.
