Use the tutorials here if you want to just use the standard APIs such as the
EAI and/or SAI to access the browser functionality. This can work for basic
integration into a standard application.
If the standard interfaces are not good enough for your needs then you may
need to build a custom integration solution. For example you want to modify
the caching strategies used during file loading or a different renderer
implementation. For most application development, you should not need the
advice in this section. First work out if the EAI/SAI is not sufficient for
your needs before you get involved in here. You should only read these if
you're already building custom code using the
Extending Xj3D documents.
