Overall implementing the terrain generation and height map was not overly difficult. The first problem I came across was editing the ruby file we created in the tutorial, in order to orient the terrain in the same aspect as the camera. The grid value had to be switched to the center in output as well […]
CS 330 Lecture 18 – A Logo REPL
Agenda what ?s why write our own languages? program this building an interpreter… …with a REPL TODO Nada. Though you wish to write more exam questions and post them in the comments. The more questions you come up with, the fewer I’ll come up with. Program This Code Logo.g4 makefile Note to copy and pasters: […]

Loading .obj meshes into my scene was a relatively straightforward process. I essentially created an array of programs, attributes, meshes, albedos, etc., and looped through each one in the OnDraw() call to display each one. In order to display copies of a mesh, I actually used a vector of vectors of xform matrices. This sounds […]

This feature is all about lighting. We’ve covered this all in great depth in class already, so there really wasn’t a whole lot that gave me any trouble. The lighting includes ambient, diffuse, and specular lighting (using the Blinn method in particular). Everything I used as a reference came directly from Chris Johnson. Here are […]

Loading a .obj mesh is a relatively straightforward task using the masterfully written code provided to us by Chris Johnson (Extra Credit?). I decided to augment the ObjUtilities class to make it slightly more robust. The utility can now handle comment lines or other odd lines throughout the file, as well as count the vertecies […]
Feature 5
Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/twodee/blog/wp-includes/wp-db.php on line 3030
In order to get this feature to work I had to do two main things: Add a terrain class that I could use to sample the terrain height at a given location, and improve the camera class to function more like a fps camera. My terrain class is a height map that is generated from […]

Generating terrain wasn’t terribly hard. At first, I wanted to write my own generator, with an algorithm other than diamond square. I wanted a landscape that resembled mountain ranges more than rolling hills. I got about half way there. The issue was all of the mountains looked like long, skinny ramps due to the order […]
