X3DToolKit Documentation

1.0.0

X3DToolKit is a LGPL free C++ library for loading displaying and processing X3D models. It has been designed so that extending the X3D language is easy.

Different uses of the library are possible:

• simply load and render static X3D models in OpenGL
• load and traverse the scene graph in order to edit it or simply extract informations
• extend easily the X3D language and use the new nodes in the two first use cases.

The library is made up of three views of the X3D model. There are three scene graphs, which have a common interface.

• the X3D scene graph providing a simple translation of the file into a more usable data structure.
• the GL scene graph based upon nodes specialized in rendering
• the MESH scene graph providing fully customizable template mesh structures.

To traverse the scene graphs taking in account the class hierarchy, the "double dispatching" technique is emulated, providing a way of factorizing code. The library provides also a set of functionalities, ie processors that traverses the scene graph and processes each node.

The library doesn't implement all the X3D nodes and does not contain a complete X3D browser but the rendering of static objects is fast. In the case of off-screen rendering, or image saving, you can use the X3DTK::Image class briefly explained here.
