Creating OpenNI Modules

This help document presents a tutorial showing how to build new module OpenNI implementations.

OpenNI is a plug-in system. It defines the interfaces and data flow of common 3D computer vision types.

The OpenNI MPI lets you create new OpenNI modules. An OpenNI module is a shared-library which exports one or more node implementations.

This section presents the necessary steps for creating an OpenNI module.

Note:

OpenNI native interface is written in C. However, just as there are C++ wrappers for the API, there are also C++ wrappers for creating modules. Using the C++ wrappers is the easiest way to create a new module, so all further descriptions will assume the use of C++. Creating new modules in C is not covered currently in this documentation.

This tutorial comprises the following major sections. Work through them in the order given.

1. Defining the Node Topology
2. Creating a Node Implementation
3. Creating a Node Exporter
4. Module Entry Points
5. Registering the new Module
