Directions for Running on CADE machines:

to source folder (/source/)

type: ./output

Directions for Running on OSX:

GLUT

Known Bugs:

No known bugs.

Usage:

The program displays a flag drawn pixel-by-pixel. There is no further functionality.
Press 'q' to quit the program.

Difficulties:

The greatest challenge and difficulty of this assignment was designing the stars. To draw the stars using only points I found a sheet of graph paper and drew the outline of a star. I then chose which points I wanted to shade and wrote code to shade these points beginning at the top of the star and moving down. This code was then placed within a drawStar method that was called 50 times within the last portion of the code.

I also found it a little difficult to get the getting_started.zip example compiling on both OSX and Linux, although the fix was simple and it was very nice having a small base code to work with.

What I learned:

I learned how the triangle rasterization works and I had an opportunity to actually implement it. It was even somewhat fun to really think through drawing images with just pixels works.

I leanred about putting all the OpenGL commands between the correct beginning and ending commands, and I learned that the window coordinate system is upside down from what I'm used to (where the top left corner is 0,0). That threw me off for one second, but wasn't a big deal.
