Computer Graphics (CS 330)

Project No. 2 (15 points)

Problem:

• To create a 3D image, consisting of three colored polygons, based on data stored in a text file.

Task:

• Create the following classes:
• myPoint: data members include a coordinate triple (x,y,z) and a pointer to myPoint objects
• myPolygon: data members include a pointer to a list of myPoint objects, the number of points (vertices) in the polygon, and the color of the polygon stored as an RGB triple
• Using C++, OpenGL and GLUT, and these classes, create a Win32 Console Application program that will read a set of polygonal data from a file and then render the polygons using perspective projection.
• Produce three renderings of these polygons
1. Using the vertex data as given
2. Translating the third polygon by (0, 10, 50)
3. Scaling the second polygon by (-1, 2, 1)
• Submit your project according to the Project Submission Guidelines for this course.

Notes:

• Keep it simple. Don't try to do more until you succesfully complete the project as described above.
• You do not need to use the DDA you created for Project No. 1.
• You may use whatever window/viewport/point-of-view settings you wish as long as all of the polygons are visible in the final rendered image.
