This is an online VR 2-players co-op puzzle game. Players use laser guns to interact with portals and other objects in order to find their way back to earth.

My primary role for this project is technical artist and gameplay programmer. As a technical artist, I've implemented global cel-shader material, portal VFX material as well as several other shaders for in-game props. As a gameplay programmer, I've implemented multiple gameplay mechanisms for props, UI/UX system and a dialogue system.

This is a Ocean Simulation shader based on my own Raytracer.
The shader is written entirely in GLSL and runs under OpenGL framework.

My work includes Gerstner wave function for ambient ocean wave, circle wave function for ripples, generating sand using perlin noise and light system.

Warped is a 3D top-down isometric puzzle game where player must escape from a mysterious underground temple by rotating the magical rooms they're trapped in.

My primary role for this project is gameplay programmer and tool programmer. As a gameplay programmer, I've implemented the entire rotation system in the game as the main mechanism. As a tool programmer, I've implemented multiple animation spline functions for artist to use in cutscene.

This is my own global illumination Ray-tracer that allows user to define triangles and spheres and render them on gpu.
There are multiple styles of procedural shaders provided inside of the GI framework. Checkerboard, perlin-noise and other customizations can be applied to shapes.

Mirrored and transparency effects are available for both spheres and triangles. User can select different kinds of tone-reproduction effects after rendering the image.

This is my own CPU Ray-tracer and a rasterizer that allows imported models and textures.
The program uses Eigen3 for geometry computation and OpenCV for visualization.

This is a small python program I wrote using OpenCV to create animation effects, sketch effects and watercolor effects for photos.
