An economic simulator with low-poly 3D visualization, developed for the Computer Graphics and Virtual Reality course.

Description

An interactive application that combines economic simulation mechanics with real-time 3D rendering using OpenGL. The player manages a company by constructing buildings, buying and selling resources, and watching their industrial city evolve visually as the business grows.

Requirements

• Python 3.8+
• PySide6
