About Me
I'm Rahul Kumar — a Game & VR developer focused on building immersive, technically grounded interactive experiences. My work spans Unity 3D, VR/AR development, and computer vision with OpenCV, and I enjoy turning hard engineering problems into polished, performant prototypes.
Currently pursuing B.Tech (Mechanical) at IIT Mandi, I've shipped VR interaction systems, AR glasses for the visually impaired, and real-world flood simulations using photogrammetry — always with a bias toward performance, clarity, and good UX.

VR Development Intern
Built research-grade VR interactions and headset integration — prototyped locomotion systems, hand-tracking controls, and rendering optimizations for standalone headsets.
- Designed hybrid teleport/smooth locomotion to reduce motion sickness.
- Built custom input handlers for tracked controllers; integrated OpenXR.
- Optimized shaders & draw calls to hold a steady 72+ FPS on target devices.
- Collaborated with the hardware team on camera streaming & latency tests.
AR Glasses Development Intern
Developed an AR-glasses solution to assist visually impaired users — combining real-time vision with intuitive feedback.
- Built interactive UI systems in Unity with backend logic wiring.
- Used OpenCV for real-time frame processing across multiple camera modes.
- Implemented UDP communication for efficient inter-module data sharing.
- Reviewed and mentored student projects on code structure & workflow.
Freelancer — VR Environment & Simulation
Designed flood-simulation experiences and photogrammetry-driven environment builds for VR research.
- Implemented player movement & interaction across VR environments.
- Captured real-world locations via Polycam, refined in Blender.
- Configured HDRP water systems; optimized to 90–110 FPS.
- Visualized live flow parameters from the hardware/cloud team.
B.Tech, Mechanical Engineering
Coursework in Modelling & Simulation, CFD, and CAD — bridging mechanical design with VR/game projects.
- Relevant coursework: CFD, Modelling & Simulation, 3D Printing, CAD
- Activities: VR research group, LiDAR mapping
Senior Secondary (XII)
Focus on Science & Mathematics — foundation for engineering and computer graphics work.
