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, […]

Generating terrain from a height map was not necessarily a very difficult task, but of course, I managed to make it difficult anyway. Honestly, the craziest part for me was simply figuring out how to actually access the pixel color values of an image. I scoured the web for simple ways to read in a .png file […]
