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!

_Originally posted to blogs.oregonstate.edu on Apr 6, 2023_
|
||||
|
||||
To begin my inaugural post in this series I’d like to tell you a little bit about myself. My name
|
||||
is Andy, and I’m 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 I’ve 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 didn’t). Instead of
|
||||
continuing my education I went to work for an insurance company. While I wasn’t 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. I’ve led projects, participated in
|
||||
teams, collaborated in multi-disciplinary settings, and worked alone. One thing I’ve learned about
|
||||
myself is that I am adaptable. I honestly don’t know what role I might settle into as a programmer
|
||||
in a room full of other tech people because it’s 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, I’ve done it many times before. That’s not to say I don’t 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 can’t 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 it’s 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 it’s like to work collectively on a codebase. My previous classes have prepared me with theory
|
||||
and isolated exercises, now it’s time to put that knowledge to use.
