Programming Assignment 1

This programming assignment is due 09 September 2022 and may be worked on in pairs.

1 Drawing OpenGL Primitives

1. Rename testline.html and testline.js from problem set 0 pa1.html and pa1.js respectively and modify them to demonstrate drawing:
   • points,
   • lines,
   • triangles,
   • quads, and
   • polygons.
   Your modifications should also demonstrate at least 2 of the following:
   • loop,
   • strip, and
   • fan.
   You should use at least 3 different colors. Be creative and generate an interesting image.

2. Describe the effect or results of the following situations. Provide the most general description possible and include your answer in your source code:
   • When drawing lines, 3 vertices are passed.

   • When drawing lines, 4 vertices are passed.

   • When drawing triangles, 4 vertices are passed..

   • When drawing a triangle, a different color is associated with every vertex.

   • Are quads and polygons supported natively?

2 Turning it in

Clone your class repository (<your username>@gitter.csse.rose-hulman.edu:/srv/git_repos/2223a-csse351-<your username>).

Include your answers in your source code. You should place your files (including any modified files) in the appropriate directory (PA1) in your cloned class git repository and then commit (add, commit and push) them.
