3D Modelling, Computer Graphics [Mar’19]

Implemented meaningful views for 3D objects (solid modelling) in C++.

Provided capabilities to manipulate visual and geometric information using computational techniques. For example, zooming in/out, shadows/light effects, etc.

Snake Game: [Sep’ 19]

Developed a Snake game. A single-player game where the user can play within the given UI.

The player man oeuvres a line which grows in length, with the line itself being a primary obstacle.

The player controls a dot, square, or object on a bordered plane. As it moves forward, it leaves a trail behind, resembling a moving snake.
