polydraw 💎

A rasterized shape drawing application, inspired by GeoGebra Classic, developed as part of a UI design assignment. This application allows users to draw various rasterized shapes with a simple and intuitive interface, focusing on user experience and design principles. The project report, which details the design process and key decisions, is available here.

Main features

• Scalable coordinate system with drag to move.
• Supports DDA and Bresenham line drawing algorithms.
• Configurable line attributes (type, thickness, color).
• Draw polygons (regular and irregular).
• Configurable polygon attributes (border color, border thickness, fill color).
• Circle drawing using midpoint circle algorithm.
• Animated transformations (translation, rotation, shearing, …).
• Ellipse drawing using midpoint ellipse algorithm.
• Shape clipping.
• Drag and drop to move shapes.
• Testing with JUnit 4.
• Sidebar with opening and closing animation.
• In-app tutorials with searching functionality.
• Cross-platform GUI.
• Export canvas in PNG and JSON format.
• Keyboard shortcuts.
• Supports undo, redo, and delete operations.
