  Authoring Gibbon Brachiation in Offline and Real-time Applications

  This work presents two methods for authoring motion resembling gibbon brachiation in digital content creation software: one using key-based animation in Autodesk Maya and one using physical simulation in Epic Games' Unreal Engine. Although this problem has undergone many iterations in 2D, the presented approaches generate brachiation animations in 3D.

  Populous: L-system-derived roadmap generation

  I've been working on several projects for VIZA 626 Generative Art and Design this spring. Most recently, I created Populous, a WebGL city roadmap generator based on the 'Procedural Modeling of Cities' paper by Parish and Müller.

  Argonaut: Particle & RBD Simulation

  Building off my WebGL ray tracer, I created a visualizer for techniques in physically-based modeling as part of an independent study in fall 2021. I worked from a textbook on the subject by Dr. Donald House and Dr. John Keyser. My objective was to support particle and rigid body dynamics simulations in the browser.

  Ray Tracing in WebGL

  I created a second ray tracer in WebGL from scratch for VIZA 656 Image Synthesis at Texas A&M in spring 2021. Building it in WebGL afforded cross-platform compatibility, albeit with the tighter restrictions of GPU programming. I could practice the lower-level aspects of creating a ray tracer, such as assembling materials and dynamically generating shader code at runtime. The ray tracer supports spheres, planar surfaces, triangle meshes, and various types of lights. In addition, I implemented texture maps, bump maps, reflections, refractions, distribution ray tracing effects such as subframe motion blur and imperfect specular phenomena, linear animation keyframing, and image sequence exporting.

  Hand-Drawn Ray Tracing

  In spring 2019, my project partner and I extended our computer graphics professor's C++ ray tracer to support adaptive parallelization on RPI's IBM Blue Gene/Q supercomputer and to render 3D meshes in a hand-drawn style. Before this, we individually implemented much of the functionality of the ray tracer in course assignments. My partner ported the ray tracer to the Blue Gene architecture, wrote two static parallelized algorithms, and handled mesh edge rendering. I implemented the hand-drawn texture generation and the adaptive parallelized algorithm. Dennis Haupt (from Free3D.com) created the wooden watchtower model used in the renders.

  Over EZ

  I wrote a MEAN stack application to simplify the creation of a weekly email newsletter for the Alpha Phi Omega chapter at RPI. It was developed, on and off, between April 2017 and July 2019.
