title: "Graduation"

Hi all, sorry for the huge delay in updates, hopefully you can cut me a just little slack... __as I
finally graduated!__ I took an admittedly long break after classes ended in June and I am so happy
to be able to say that I have officially completed my bachelor's degree in Computer Science. I was
just going over some of my projects this afternoon as I continue to refine my CV and it's really
incredible how far I've come. Like many of life's great moments I couldn't have done any of this without
support, and I want to thank my partner Valerie. From the bottom of my heart, I appreciate all that
you've done to help me on this journey.
My final projects for Computer Graphics Shaders as well as Intro to Databases went exceptionally
well. For my shaders class I chose to create a realistic motion blur based on documentation in Nvidia's
[GPU Gems 3](https://developer.nvidia.com/gpugems/gpugems3/part-iv-image-effects/chapter-27-motion-blur-post-processing-effect).
I was rather excited about this project and I'd like to go through a few details for anyone who might
be interested, otherwise feel free to skip ahead.
I used a two pass process with OpenGL and GLSL in which I first simply rendered an object to a texture. Then to create a
per-fragment blur effect I sample the depth buffer in the fragment shader to find each pixel's current
position and world position.
// Sample depth buffer
float dbAtPixel = texture(uDepthBuf, vec3(st, 1.));
// Find view position
vec4 viewAtPixel = vec4(s * 2 - 1, (1 - t) * 2 - 1, dbAtPixel, 1);
// Convert to world coords, -1 to 1
vec4 worldPos = viewAtPixel / viewAtPixel.w;
Next, I multiply the world position by a "blur position" (a stand-in for the
direction of movement) to find a previous position. This allows me to calculate a velocity.
// No previous view in a static image, so we make one up with uBlurPos
vec4 prevPos = worldPos * uBlurPos;
// Put in range -1 to 1
prevPos = prevPos / prevPos.w;
// Find pixel velocity and scale it if desired
vec2 velocity = uVelScale * vec2((currPos - prevPos)/2.);
In the third and final stage I sample the color buffer in a loop, using the velocity to cacluate
each fragments color. The number of times the color buffer is sampled directly impacts the quality
of the effect, with higher sample rates resulting in a smoother and more realistic blur.
// Sample color buffer
vec4 color = texture(uColorBuf, st);
// Add velocity to st coords
st += velocity;
// Continue sampling color buffer until preferred number of samples is reached
for (int i = 1; i < uNumSamples; ++i, st += velocity) {
vec4 rgba = texture(uColorBuf, st);
color += rgba;
}
// Average samples to get blur color
color = color / uNumSamples;
Of course, all of that was very boring if you don't know what it means. Let's see what it actually
looks like!

With those two classes completed I began the spring term and my final Capstone Project, a three
month long grind to produce a complete piece of professional quality software. I was grouped with
two other students and selected for the "3D Escape Room Game" - a video game intended to mimic the
experience of a real life escape room. This was the first full video game we had ever created so
naturally I was incredibly excited, but quite nervous too! I'll have a lot more to say about this
project in the near future, I was required to write a few blog-style assignments so I intend on
posting those as a series too. Unfortunately I don't think I'm allowed to make our code public, but
on the bright side you will be able to download and actually play the game!

title: "Capstone Blog Series #1: Introductions"

_Originally posted to blogs.oregonstate.edu on Apr 6, 2023_
To begin my inaugural post in this series Id like to tell you a little bit about myself. My name
is Andy, and Im excited to have you all with me as we navigate the next three months. I was
interested in computers at a very young age, and I went on to build my first desktop when I was in
high school. Since then Ive built many more as well as a few home servers to host my own cloud
services. Despite my interest in computing I had always considered it a hobby, and my first degree
was in Ethics, History, and Public Policy. I thought I wanted to be lawyer (I didnt). Instead of
continuing my education I went to work for an insurance company. While I wasnt sure whether
insurance would be my career, I liked the people I worked with and it paid the bills. I ended up
working in claims processing for seven years until, unfortunately, I experienced some health issues
that forced me to leave the workforce altogether. It was not a happy time, yet as with any
life-changing event it also brought new perspective. As I began to recover I realized that, despite
the setbacks, I had a very rare opportunity to pursue an entirely new course in life. Where I had
previously only considered tinkering with computers a mere hobby, I became determined to leverage
my skills and start a new chapter.
I have taken on many roles in both my work and personal life. Ive led projects, participated in
teams, collaborated in multi-disciplinary settings, and worked alone. One thing Ive learned about
myself is that I am adaptable. I honestly dont know what role I might settle into as a programmer
in a room full of other tech people because its a new experience for me in many ways. However, I
am becoming increasingly confident in my ability to rise to a challenge, and I suspect that my
flexibility will continue to be an asset in this new setting as well. I am not particularly nervous
about working in a group, Ive done it many times before. Thats not to say I dont have concerns
though. Namely, group work is rarely fair. Different people have different talents, expectations,
ambitions, and the list continues. It is my hope that my teammates and I are able to communicate
well enough that our contributions are equitable, even if they cant be perfectly equal.
I was actually quite overwhelmed when I first browsed the list of projects that are available for
this term. Did I want more experience with low-level programming? Embedded systems? An industry
project? It was a lot to absorb. I gradually began to narrow things down and, to speak plainly, I
selected the projects that sounded like the most fun. I have no doubt the process will be
educational too, but considering its my last term at OSU I also wanted to create something that
would be meaningful to me personally. To that end, I focused on projects that would allow me to
enhance my skills with operating systems/computer architecture, graphics, and games. In addition to
learning more in those areas of personal interest, I also hope to gain a better understanding of
what its like to work collectively on a codebase. My previous classes have prepared me with theory
and isolated exercises, now its time to put that knowledge to use.
