SVG and 3D OBJ export from image

A C++20 port of VTracer for converting raster images into SVG files and 3D OBJ files. The repository includes a native library, a command-line application, and a Windows .NET 10.0 MAUI frontend. The MAUI project is configured for Windows and Mac.

Requirements

• CMake 3.20 or newer
• A C++20 compiler
• Visual Studio 2022 with C++ desktop tools (Windows)
• .NET 10 SDK with the .NET MAUI workload (for the GUI)

Build the native targets

cmake -S . -B build-native
cmake --build build-native --config Release

This builds:

• vtracer_core - C++ tracing library
• vtracer_native - shared library with a C API
• vtracer_cli - command-line application

Use the CLI

.\build-native\Release\vtracer_cli.exe --input input.png --output output.svg

Run vtracer_cli --help to see all tracing options and presets.

Run the MAUI application

dotnet workload install maui
dotnet build .\VTracerMaui\VTracerMaui.csproj
dotnet run --project .\VTracerMaui\VTracerMaui.csproj

The MAUI project builds the native tracer automatically through CMake.
