Pathtracer

A physically-based renderer using a pathtracing algorithm. Incorporates ray-scene intersection, acceleration structures, physically based lighting, complex materials, environment lighting, and depth of field effects.

Color in Nature Inspired Design

Combining smart color schemes with cellular automaton and reaction-diffusion system.

MeshEdit

A mesh editor that allows you to load and edit basic COLLADA mesh files. Uses de Casteljau's algorithm to build Bezier curves/surfaces and half-edge data structure to manipulate meshes. Also includes an implementation of loop subdivision.

Real-time Cloth Simulator

A real-time cloth simulator using a mass and spring based system. Simulates cloth movement and calculates forces using numerical integration. Handles collisions with other objects (e.g. sphere) and self-collisions to prevent cloth clipping.

erth.io

A multiplayer battle game in the ever-growing list of .io games. This time you control a colored circle and can choose a class (archer, magician, or warrior; each has its own unique attack and power)

Colorizing Photos using Alignment

Align digitized glass plates to form colored versions of those images. There were two alignment approaches we were required to implement: single-scale and image pyramid.

Filter and Frequencies

Implemented various derivative filters to perform useful tasks such as image straightening. Applied filters to help sharpen images, create hybrid images, and implemented image blending operations using Gaussian and Laplacian stacks.

Face Morphing

Face morphing using triangulation and affine transformations to output new, interpolated faces (or extrapolated for caricatures).

Autostitching Mosaics

Recovered homographies, warped images (with 2 rectified images as examples), and blended my own images into a mosaic.

Seam Carving + Gradient Fusion

Implemented verticla and horizontal seam carving as well as gradient domain fusion, performing poisson blending.

Neural Coreference Resolution

Built a PyTorch implementation of a neural coreference system using a mention-ranking model with word embeddings and mention distance features.

Transition-based Dependency Parser

Checked projectivity of dependency trees used, created an oracle method to convert trees to configuration and action pairs, and used oracle data to train neural network to predict actions given a configuration.

Enigma Machine

A simulator for a generalized version of the Enigma Machine. The Enigma was used by Germany in World War II to encrypt millitary communications.

Amazons

A simulated Argentinian strategy game, including minimax AI bots that can force wins within a dozen moves.

Rasterizer

A simple rasterizer that includes features such as supersampling, hierarchical transforms, and texture mapping with antialiasing. It is a fully functional vector graphics renderer that can take in modified SVG (Scalable Vector Graphics) files.

ML Cellular Automata

ML detection of interesting 2D CA.

NOME

Interactive CAD tool.
