This project entails the creation of a Javascript-based world simulation for focused meditation. We hypothesized that we could facilitate the meditation process by designing a dream-like world in which users can customize their own calming terrain through the perspective of a flying bird while listening to peaceful music and guided meditations.

With the COVID-19 pandemic affecting more people each day, we wanted to explore ways to remain calm and reduce stress through meditation. We were successful in our goal of creating this simulation, and in particular achieved our target results: the implementation of infinite terrain generation, realistic bird movement, and music and terrain (i.e. audiovisual) coordination.

The goal of this project was to create a graphical representation of the solar system, including its planets, major moons, and other prominent objects like dwarf planets, asteroids, and comets. In this program, planets are accurately positioned in the simulation according to their orbital data, so the user can see an accurate spatial layout of the solar system. Celestial bodies are rendered with great visual accuracy, using available textures and carefully tuned reflection models. The user may move the view throughout the solar system, zoom in on different objects, and look around using mouse controls.

This fall semester, Princeton University is offering a new class DRI 101: Driver’s Ed. Our game, Driver’s Ed, is an infinite-runner game in which a player controls a car driving down Washington Road. Each player is given three lives (or three chances in the class), and every time they hit an obstacle they lose a life. The player uses the arrow keys to dodge the obstacles— pedestrians, crossing animals, and other cars— all while trying to collect coins.

The goal of the game: get as many coins as possible without getting kicked out of the class. Driver’s Ed uses computer graphics concepts, such as polygonal meshes, light rendering, and collision modeling, to create an enjoyable and aesthetically-pleasing game for players.

Endless runner games have become increasingly popular in recent years. Inspired by the successful work of Temple Run and Subway Surfers, I implemented a similar game called Cat Dash, where players control a cat to avoid obstacles and earn rewards. To enrich the game interface, scenery are randomly generated and spawned along sides of the cat’s moving tracks. Optimizations have been done to guarantee the game’s playability and compatibility, and enhance algorithm efficiency.

Based on the comprehensive experiments and tests, the game runs smoothly and bug-free with different screen sizes and browsers.

Chromatic Arrow is an archery-based web game developed using the ThreeJS library. Its core gameplay consists of shooting arrows at targets that randomly spawn in 360 degrees around the player. Arrows follow the laws of physics, so the player must account for gravity and wind while aiming. There are also invisible barriers throughout the scene that will block the player’s shots; barriers are revealed by paint splatters whenever an arrow collides with them.

The more the player shoots, the more of the level is uncovered. Points are scored by hitting targets and revealing barriers before time runs out.

We explore an alternative technique to raytracing for rendering 3D scenes called Signed Distance Field Raymarching that represents the entire scene using a signed distance field (SDF) that maps each point in space to the distance to the nearest object. We are able to implement comparable features to the raytracer in assignment 3 at near real-time frame rates (10-30 FPS). We also render a scene that would be infeasible to produce with raytracing due to its recursive nature.

We highlight the composable nature of the SDF representation by building an editor that allows users to build complex shapes by composing primitives with transformations.

Going Viral is a COVID-19 themed arcade-type survival game. You, the player, control a healthy white cell while trying to avoid infection by enemy virus particles. You control your cell with the arrow keys and the spacebar (to jump). As you successfully complete levels, the game becomes more difficult, challenging the user to be more daring. Stay Healthy!

Pac-Atac is an exciting first person shooter game inspired by nostalgic Pac-Man aesthetics and first person shooter classics. Players play as Pac-Man and attempt to survive for as many waves as possible by shooting cherries and other assorted fruits to defeat the unrelenting ghosts.

Developed using ThreeJS, Pac-Atac reconciles dynamic game-design and visually-exciting graphics concepts to promise an action-packed 2.5D experience in the spirit of Pac-Man.

mpThree.js is a music-adapting retro racer that is powered by YOUR music. Users upload their own .mp3 files, and the game elements interact with the music to create a unique experience. Over the course of the song, players avoid red ‘death spheres’ and try to collect gems and power-ups to rack up as many points as they can.

Princeton 2020: A Space Odyssey is a space flight game where the player must navigate an ongoing asteroid field while also collecting enough fuel to survive. Players can hope to join an exciting, flight-centered space adventure.

Pilot a spaceship flying through outer space as you attempt to warp home by collecting fuel charges. The primary objective will be achieved by the player collecting fuel charges as they spawn while avoiding flying asteroids or picking up power-ups to become invulnerable to asteroid collisions.

3D Knockout is a 2 – 4 player game based off of the 2D Game Pigeon game “Knockout,” in which players launch their penguin characters with specified magnitude and direction in an effort to knock the opposing player’s penguin characters off of the ice sheet that the game is played on. A player begins with four penguin characters and wins by knocking all of the opponents’ penguins off the ice sheet while having at least one of their characters remaining in the end. Each player gets one opportunity to “launch” their penguins per round, and the penguins begin to move according to the user’s instructions simultaneously at the end of the round.

In our project, we managed to implement all of the key aspects from the original 2D game into a visually appealing 3D scene containing the icy playing field, an animated ocean, mountains, and several dynamic, exotic creatures. However, we also implemented other cool features such as incorporating a scoreboard, sound effects, a rotatable camera angle, and the ability to play with 2 – 4 players.

Type Type Revenge is a 3D web game built with ThreeJS to provide an interactive environment for users of various typing levels to practice their typing skills. In this game, random letters fall down the screen in time with music, and players must type the corresponding keyboard key as a letter reaches its target at the bottom of the screen. There are two song options and three levels of difficulty offered, and point values increase as the player reaches longer streaks of successfully typed letters.
