CST 325 - Module 3


This week involved learning about matrix math, how matrices are used in graphics programming, and how matrices are especially important to graphics programming as they are used to represent transformations of 2D and 3D space - which is the very nature of computer graphics.

 Implementing matrix3.js and matrix4.js was more difficult to me relative to vector3 and vector4 due to my little experience working with matrices, but once I figured out the mathematical concepts both APIs came together smoothly. I still need to spend more time wrapping my head around the more abstract concepts of matrices and thinking of them as representations of space transformations other than rows and columns of numbers to be multiplied, but after watching 3blue1brown's videos and reading some resources online I feel as if I have a better understanding and appreciation of them than I did before.

 Out of curiosity, I looked up Unreal Engine's 4x4 matrix API documentation and I was pleased (and surprised) to find that it isn't so different from what I just coded for this week's assignment. Maybe my difficulties now as a beginner will help me out later when I have to work with real graphics engines such as Unreal or Unity.

CST 499 - Week 7

This week, our group finished recording and editing our capstone project video and prepared our presentation for the capstone festival. Although I wish the capstone festival was held in person (and it could not due to current circumstances), I am excited to show off our project and hard work to other computer science students, friends, and family. I hope they'll enjoy it and learn something cool while doing so.

The Final Journal

It's the end of a long, four year journey, and what a journey it has been. I never thought I could pull off finishing my second bachelor's degree four years ago when I first went to that introduction to programming class at my community college. I would like to thank all the friends I've made along the way and the people who have helped me through the last two years. Although it was difficult at times taking class while working 40+ hours a week, I'm proud of myself for making it through. I don't think I'll be a student enrolled in classes anytime soon, but I'll always be a lifelong student. See you all around.

CST 499 - Week 3

This week, we finished our ILP portfolios and turned in the final versions of our resume and cover letter. My group also completed the first part of the capstone report. I'll admit that creating a portfolio showcasing my past work was not at the top of my priority list when I first started studying computer science, although at this point in my educational and professional career I've learned how important it is to have such a portfolio. Like other creative professions, having a solid body of work to show to a potential employer, or even for personal documentation is one of the best ways to display your talents as an engineer. Also, all the assignments I've completed during my academic career, both at CSUMB and elsewhere, have given me a good start to my portfolio. I tend to prefer classic, plain styling like  Brian Kernighan's  home page (he has a pretty nice portfolio too), although I've come to appreciate highly stylized portfolios that make use of WebKit ani...
