Intelligent Adaptive Splitting for Vector Representations
2021-2023 Awaiting submission
A universal splitting metric for vector representations across both spatial and temporal domains. This allows for efficient meta-parameter discovery for discrete handles and keyframes.

HOBBY & UNDERGRAD
OpenVCB Circuit Design Game
Summer 2023 Hobby
Hobby project building a better version of the game Virtual Circuit Board from scratch to include a faster simulator and generally more features with less limitations. I wanted to design my own GPU and the original game was simply too slow.
Parts of the code can be found at github.com/kittybupu/openVCB. The Unity project itself remains unreleased. Please don’t sue me for copyright.

Pixelite GI: Raytracing Pixel Art with RESTIR
Summer 2022 Hobby
I like pixel art. I like raytracing. I like raytraced pixel art. This was released as a Unity plugin which implements a hybrid RESTIR multi-bounce GI and raster graphics rendering pipeline using compute shaders.
The plugin can be found at pixelite.dev through the Unity Asset Store. Although, I unfortunately no longer have time to maintain it.

2D SPH Fluid Simulation With Two-Way Coupled Rigidbodies
Purdue University 2019
A 2D SPH fluid simulation that leverages compute shaders in OpenGL to dramatically speed up frame times. The fluid particles are simulated with a spatial hashing algorithm synchronized with atomics. Integration was done with RK4. Solids are simulated as fluid particle clusters with particle impulses obtained through parallel reduction. Rendering is done through the use of a variable radius blur combined with a threshold function. On a RTX 2070 Super, the simulation can support up to half a million particles with ~5ms per time step (dt=8ms). The video on the left is playedback at realtime on my laptop with each scene containing ~100k particles.

High Performance Large Protein Visualization in VR
Purdue University 2018
I worked under Prof. Gurav Chopra and the Envision Center visualizing protein molecules in VR. I started with a simple instanced renderer. From there I implemented billboarding to reduce the poly count; a compute-based atom culling algorithm to address fill rate bottlenecks, a fluid rendering inspired iso surface renderer to address Van Der waals shells, and octahedral imposters to address background rendering. I came up with the idea of running a linear regression on the atom positions to better align axis-aligned-bounding-boxes. I ended up with the ability to render 50k+ atoms complete with labels and bonds at the speed and fidelity VR applications require.

C++ ECS Game Engine
Monta Vista Highschool 2017
A 2D game engine written from scratch using OpenGL and GLFW. It has a build-in constraint based physics engine with a SPT broad phase. Similar to Unity, it was its own transform parenting system and an implementation of several GUI functions like: GUI event dispatches, anchored based UI scaling, instanced atlas text rendering and sliced sprite rendering.
