Computer Graphics Algorithms (C++ Builder)

This repository contains implementations of fundamental computer graphics algorithms and geometric transformations, developed using C++ Builder (Embarcadero / RAD Studio) as part of the Computer Graphics course at UTFPR.
The project focuses on classic algorithms such as line drawing, transformations, clipping, curve generation, and basic 3D object visualization.
