VisiCut is a Java Swing desktop application for preparing, previewing, and sending laser cutter jobs, primarily used in makerspaces and fab labs. It is not a web service or data pipeline; the repository is wholly an application. The UI is built around a singleton VisicutModel and file-based managers (MaterialManager, ProfileManager, LaserDeviceManager, MappingManager) that persist XML configuration. The main entry point is VisicutApp.main(), with MainView as the monolithic controller for file I/O, camera handling, job execution, and settings import/export. Core data flow starts with importing vector/raster files (SVG, DXF, EPS, JPG/PNG, GCode, LaserScript, parametric SVG) into a GraphicSet, then users map graphic objects to laser profiles (cut/engrave/mark) via MappingSets. The model assembles LaserJob parts and hands them to the external LibLaserCut library for device-specific communication. Camera support includes periodic refresh, homography-based calibration, and QR/FabQR upload. Vectorization uses external potrace and mkbitmap binaries. Maintenance is currently active with recent commits, but the codebase carries significant technical drift: old JVM-era dependencies, NetBeans-generated .form files, XStream serialization, direct Runtime.exec, hardcoded URLs, and incomplete translations. It has a few genuinely reusable components (Homography math, unit-aware input fields, drag-drop file support, warning panel) and decent tests for core utilities, but the main view is bloated and heavily coupled to legacy desktop frameworks.
