Feature 5
This time, I gave my camera the ability to walk around the map with its height varying with the height of the land. The first thing I did was create a class called Heightmap, which held a width, a height, and a 2D array of floats (heights). Then, I made a couple of new methods […]
Feature 5 Post Mortem
Adding a camera to my terrain came pretty quickly after I generated my terrain, but it took me a while to iron out all the bugs. I also feel like I went at the problem in kind of a strange way, but I’ll get to that later. My cameras controls use WASD for advancing and […]
CS 330 Lecture 20 – A Logo Compiler with Conditionals and Loops
Agenda what ?s interpreting vs. compiling modeling a program: follow the grammar what to do on undeclared variables? adding loops adding conditionals TODO Write a Logo program and drop it in your submissions directory in W330. Name your file todo.logo. Be exactly exact. We will have a gallery showing on Monday. You are encouraged to […]

Feature 2 Post Mortem
Generating terrain wasn’t too hard; the biggest problems I had were simple things that shouldn’t have been problems. I decided to write the diamond square algorithm in c++ because I’m way more familiar with it than I am with ruby, and there were a few things I wanted to try and play around with when […]

Feature 5 Post Mortem
I had some trouble at first getting feature 5 to work. Getting the WASD movement keys to work was as simple as setting the keys to different values from keys.h, as shown below. It also shows where I set the elevation of the camera equal to the terrain height. I also just used the […]
Feature 2 Post Mortem
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

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: […]
Feature 1 Post Mortem
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 […]
