Library

oDeveloped a Math library which supported Vector, Matrix and Quaternions calculations and some specific operations.

oCreated a File System to support creation of custom format files with functionalities like updating, data retrieval, packing various different data into a single file or multiple files and improved performance.

oDeveloped a Memory System by wrapping win32 functions, overloading new and delete operator for user defined allocation and improved efficiency.

HoloEngine (Research) – (C++)

oDesigned and created a converter that can parse data from a 3D model file for the engine.

oDeveloped an Engine to generate hologram of the 3D models in air inside a glass Hologram Pyramid placed upside down on the screen so that the reflection and refraction can generate display object inside the pyramid.

oProgrammed a hand gesture recognition device to be used to control model’s rotation, Scaling and translation.

HoloEngine II (Research) – (C++)

oExtended the Holo-Engine for Scene graph implemented Skybox, Terrain Generation, incorporated Animation Engine, Audio Engine and Hand Gesture Recognition for Model or character controls, making it a full-fledged Hologram Engine that is also multithreaded (Audio, Hand Gesture, Recognition, And Graphics).

Game Pad Controller (Research) – (C++, C#)

oImplemented Visitor pattern to check for desired collision.

oImplemented Strategy pattern to deploy different types of bombs in game.

oDesigned Flyweight pattern for font system.

oImplemented Proxies for reuse of base object to create entire 5X11 aliens’ grid.

oRecreated 1970’s arcade video game Space Invaders from scratch using design patterns, also added Multiplayer mode for 2 players and storing of User High Scores.

Real Time Networking for Games – (C#, Lidgren)

oDeveloped Client-server model for implementing multiplayer networking in games.

oImplemented network bases multiplayer functionality in a local multiplayer game.

oAdded lobby interface for allowing remote player to join the game session and play.

oChanged game architecture to handle object through queuing system.

AndyWalk - Augmented Reality,IMU Sensor, Java

oDeveloped an AR application which can detect horizontal plane in the surrounding and place characters on the plane.

oGenerated Accelerometer and Gyroscope data per second into a csv file in android.

oDeveloped the system to use accelerometer and Gyroscope to move the character in the AR plane with Tilt and rotation.
