AR app, using Meta Quest 3, that guides users to gaze at stars, connect constellations, and subtly encourages healthier posture through immersive experience. By shifting attention from screens to the cosmos, StellAR promotes both mental and physical well-being without the need for direct reminders.

A physically based animation simulation using Material-Point-Method and implicit / explicit Euler integration. Jell-o simulation is created using MPM in Taichi, and cloth mesh / volumetric 3D bunny model animation is simulated with Mass-Spring Euler integration in C++.

A program with different vertex and fragment shaders to apply different coloration / deformation effects to the surfaces of 3D models, including Sobel, Gaussian Blur, Worley Warp, etc.

Series of scenes with Physically-Based effects (Post-Processed Depth of Field, Subsurface Scattering Approx., Penumbra Shadow, etc.) using concepts of noise functions, raymarching, SDFs, and lighting.

A rudimentary version of Autodesk Maya that supports various operations, such as vertex manipulation, edge split, face extrusion, and smoothing with Catmull-Clark subdivision. It allows loading OBJ and JSON files and 3D-mesh deformation by skinning skeleton.

A basic UNIX-like operating system designed to operate as a guest OS within a single process on a host OS. It includes fundamental OS features, including priority job scheduler, foreground / background, synchronous child waiting, redirection, etc.

A Facebook-like web application, which supports user accounts, profiles, friend recommendations, and chatting service. It was developed focusing on utilizing cloud computing technologies to build a scalable application.

A path tracer with global illumination effect using Monte Carlo estimation with multiple importance sampling. It supports various surface materials, light sources, and constructive solid geometries.

A simple recreation of Minecraft from scratch in C++. It includes procedurally generated terrain, rivers, and various biomes using Fractal Brownian Motion / Perlin noise functions and L-System.

A GLSL shader program to create a planet, by incorporating various noise functions and noise function permutations to offset the vertices on the surface of the icosphere and changing the color of the icosphere. There are few controls, such as moon speed, lighting, and temperature to modify the scene.

A project that utilizes two-view stereo and multi-view stereo algorithms to convert multiple 2D viewpoints into a 3D reconstruction of the scene.

A simple rasterizer with a perspective projection camera, built from scratch in C++, that can draw scenes composed of 2D and 3D polygons.

An errand service platform that connects students with school peers to ask for or do errands and create a tighter community. It allows the users to set errand details, such as time, importance, area etc. and chat with matched peers.
