lib3mf v2.0.1 documentation¶

Welcome! This is the documentation for lib3mf v2.0.1.

lib3mf is an implementation of the 3D Manufacturing Format file standard.

It provides 3MF reading and writing capabilities, as well as conversion and validation tools for input and output data. lib3mf runs on Windows, Linux and MacOS and offers a clean and easy-to-use API in various programming languages to speed up the development and keep integration costs at a minimum.

As 3MF shall become an universal 3D Printing standard, its quick adoption is very important. This library shall lower all barriers of adoption to any possible user, let it be software providers, hardware providers, service providers or middleware tools.

API documentation¶

C++-language bindings¶

This space describes the usage of lib3mf in a C++ host application.

The C++-language bindings come in two different flavors:

If you include the header Cpp/lib3mf_implicit.hpp, lib3mf will be loaded dynamically during load-time of your host application through your operating system’s mechanism for loading libraries.

Lib3MF::PWrapper wrapper = CWrapper::loadLibrary();

The shared library file lib3mf.*. needs to reside in a path that your operating systems checks when loading libraries.

If you include the header CppDynamic/lib3mf_dynamic.hpp, Lib3MF will be loaded dynamically during run-time of your host application through an explicit call to

Lib3MF::PWrapper wrapper = Lib3MF::CWrapper::loadLibrary("LibraryLocation/lib3mf.so");

Lib3MF::PWrapper wrapper = Lib3MF::CWrapper::loadLibrary("LibraryLocation/lib3mf.dylib");

Lib3MF::PWrapper wrapper = Lib3MF::CWrapper::loadLibrary("LibraryLocation/lib3mf.dll");

i.e. you need to explicitly provide the location of the shared library file lib3mf.*.

The Lib3MF::PWrapper object provides access to all functionality within lib3mf.

Both flavors of the C++-bindings are header-only which makes it extremly easy to include them into existing projects:

Minimal Example Project¶

Minimal application code:

CInputVector: Adapter for passing arrays as input for functions¶

Several functions of the 3MF Library expect arrays of integral types or structs as input parameters. To not restrict the interface to, say, std::vector<type>, and to have a more abstract interface than a location in memory and the number of elements to input to a function the 3MF Library provides a templated adapter class to pass arrays as input for functions.

Usually, instances of CInputVector are generated anonymously (or even implicitly) in the call to a function that expects an input array.

template<typename T>
class Lib3MF::CInputVector¶

CInputVector(const std::vector<T> &vec)¶

Constructs of a CInputVector from a std::vector<T>
