1. Implement a basic OpenGL viewer. This viewer will also be used in your future class assignments.
- The window size doesn’t need to be (480, 480). Use the larger window that is enough to see the details of the viewer.
- DO NOT set the window title to your student ID.
- Total points: 80 pts
2. Requirements
A. Manipulate the camera with mouse movement (70 pts) i. Refer the camera manipulation of Blender software.

A. You have to implement all requirements in a single program. This assignment DOES NOT require each requirement to be a separate program.
- The camera of your program should initially look at a target point, similar to that of Blender.
- Provide the following three camera control operations.
A. Do not rotate the camera about a vector from the camera to the target point.
|
1. Initialize the target point to the origin (0, 0, 0) |
|
distance 2. |
1. Orbit: Rotate the camera around the target point by changing azimuth / elevation angles. (MMB (mouse middle button) in Blender) (20 pts)
2. Panning: Move both the target point and camera in left, right, up and down direction of the camera (Shift-MMB in Blender) (20 pts)
A. More specifically, translate both the target point and camera along u axis (left & right) and v axis (up & down) of the camera frame.
3. Zooming: Move the camera forward toward the target point (zoom in) and backward away from the target point (zoom out) (Ctrl-MMB in Blender) (15 pts)
|
A. A. More specifically, translate the camera along w axis of the camera frame. |
|
B. (up direction) v origi u w n (right direction) (backward direction) |
4. You MUST use the following mouse movement:
D. Using above mouse movements is essential for scoring your assignment, so if you use any other set of mouse movement or keyboard shortcuts for Orbit / Panning / Zooming, you won’t get any score for them.
iv. Toggle perspective projection / orthogonal perspective projection by pressing ‘v’ key (10 pts).
1. When the program is executed, it starts in perspective projection mode.
v. Draw a rectangular grid with lines (not polygons) on xz plane as a reference ground plane (similar to Blender). Choose number of rows and columns, size as you want. (5 pts)
3. Report (10 pts)
- Orbit: Click mouse left button & drag
- Panning: Click mouse right button & drag
- Zooming: Rotate mouse wheel
A. B.
C.
Submit a report of at most 2 pages in docx file format (MS Word). Do not exceed the limit.
The report should include:
i. Which requirements you implemented (5 pts)
ii.
A few screenshot images of your program (5 pts)
You do not need to try to write a long report. Just only write down the required information. Use either English or Korean.
4. Runtime Environment
- Your program should be able to run on systems only with Python 3.7 or later, NumPy, PyOpenGL, glfw. Do not use any other additional python modules.
- Only glfw is allowed for event processing and window & OpenGL context management. Do not use glut functions for this purpose.
- If your program does not meet this requirement, it will not run on TA’s computer so
you will not get any score for this assignment (except report).
5. What you have to submit: A. .py files
i. You can use multiple .py files for this assignment. In this case, explain how to run the program in the report.
B. .docx report file
