Houdini Plug-in Tool
In this group project, we made a Houdini plug-in tool that accurately simulates how water and vegetation interact together to produce an ecosystem.
For this project, I implemented the full back-end of the system that controls the simulation, based on this SIGGRAPH paper:
https://dl.acm.org/doi/abs/10.1145/3528223.3530146
There are many potential uses for this tool, including an accurate demonstration of the impact of climate change in order to bring about an increased understanding of global environmental issues. This plug-in also allows users to visualize local ecoclimate phenomena. We expect artists and game designers to use this tool to model a natural environment. The changing environment created by this tool creates an immersive experience, so the artist can show how their environment will change as time progresses.

Mini-Minecraft
This was a group project in which a small team of two others and I
built a mini-version of the popular game Minecraft
from scratch in C++ and GLSL.
Our project was accepted into our professor's "Hall of Fame!"
My contributions included:
- Physics Engine
(collision, interacting with terrain, flight mode, walking mode, jumping)
- Texturing
(pulling from texture atlas, alpha blending, separating
VBOs for transparency, animating textures)
- Procedurally Generating Additional Biomes
(using noise functions like Worley, FBM, and Perlin, I determined terrain/biomes using elevation and moisture)
- Procedurally Generating Assets
(procedurally added assets to the terrain
like trees, bushes, cacti, icicles, and clouds).
Helped teammates with their features:
- Multi-threading,
- Frame buffering for post-process shaders in water and lava, and
- Chunking to increase rendering efficiency

Building Mini Maya Project
In this project, I built a "mini" version of Maya
from basic fundamentals in C++.
This is a 3D object builder and manipulator. I started by implementing a half-edge
Mesh data structure, where you can manipulate face,
vertex, and edge data.
Then, you can use mesh operations, like
subdivide, which works just like Maya's Mesh smooth, to quickly
smooth the mesh.
In this project, I also implemented a skinning algorithm. The user can load mesh data, which it parses into a model, and a skeleton that will skin the mesh.

GPU Waterfall Particle Simulation
LIVE DEMO: https://kyrasclark.github.io/final-project/
In this project, I made a GPU-based particle simulation. This project is a fully physically-based particle sim with collisions all on the GPU. The particles work with transform feedback shaders, instanced rendering, and billboards, and the obstacles work with frame buffers and textures. This allows for the full system to work highly efficiently in linear time.
The user has the following controls that allow them to control the system:
- Particle Color
- Number of Particles
- Size of the Particles
- Size of the Obstacle
- Shape of the Obstacle (star or circle)
- Visibility of the Obstacles
- Camera control
- Gravity control
- Wind control (with noise option)
- Control over the generation of the particles (with FBM noise, amplitude and frequency, allowing for control over where the particles stream into the scene)

USD Full Stack Pipeline
Built a full stack USD asset pipeline, allowing users to upload, sort, edit, and download assets with version control in Python and Typescript/React.
Served as lead developer in pipeline migration between team’s 3 DB backends, rest API accessors, and front-end web applications features.
Wrote documentation for migration proposal.
Architected and implemented full stack version control tools for users to organize, edit, and share USD assets.

Motion Capture
For this project, I worked through the whole motion capture pipeline.
I captured the mocap of myself, process all the data, and applied animation blending to blend difference motions together to create a smooth result.

L-System Maya Plug-in
For this project, I built a Maya Plug-in to easily create the geometry for an L-System Tree.
It has a GUI and adds a button to the menu bar. Users can either directly add information to the GUI to create a static tree, or they may create a dynamic L-System Node that will update and preview the tree with the parameters from the user and will grow the tree, unrolling the L-System over time.
To further expand this project, I would like to test with more complicated geometry and L-Systems, as well as adjusting the parts of the tree manually with different parameters.

Building a Rasterizer
In this project, I built a rasterizer for drawing scenes composed of 2D
and 3D polygons. To begin, I developed a 2D triangle rasterization
algorithm. Then, I implemented a perspective projection
camera in order to project 3D polygons down into 2D space to be
rasterized. This video shows a demo of that 3D rasterizer, showing a
cube with texture, two polygons with z-buffering, and a 3D Mario
model with Lambertian shading.
