A node tree is composed of multiple NodeBlock connected together. These connections will then converted internally to actual Lua or GLSL code internally. It is ideal for non-programmers as they can program visually with ease without the hassle of write any code. Using a node tree allow you to virtually create exactly the same type of code that a more savvy programmer will generate manually.

Scripting node trees can also be debugged the same as code (since basically a node tree will generate code). You can set breakpoints, step over, pause etc... while Ldb will display the code path by highlighting active nodes. For more information please refer to the Node View manual.
