CS 455 Lecture 11 – Perspective and Camera
Before Class Perspective Watch http://youtu.be/k3dhGlAx_DA. For another perspective, read http://www.songho.ca/opengl/gl_projectionmatrix.html. Camera Watch http://youtu.be/-c62eQ_QpBE. For a similar implementation, read http://ogldev.atspace.co.uk/www/tutorial13/tutorial13.html. In Class It’s time to test out that perspective projection with long corridors. Your task in this class is to code up a maze traverser. Grab the maze.obj file in W455. The entrance to the maze starts roughly at (0, […]
CS 330 Lecture 15 – Makefiles, For Real
Agenda what ?s the need for separate compilation the way to manage separate compilation: make polymorphism in C: unions TODO Write a midterm exam question on something you read or something discussed in lecture. Turn it in on a quarter sheet. Some portion of the upcoming midterm will be comprised of your questions. In addition […]

Accessing the W Drive on Linux
The university kindly provides central storage to students, faculty, and staff. We can access this storage on Windows, Mac, Linux, and through a browser. On Linux, however, we end up running into some annoyances when we work with files on the W drive. (Our H drive is easy to access; it becomes our home directory, […]
