Webots nodes listed in this reference are described using standard VRML97 syntax. Principally, Webots uses a subset of the VRML97 nodes and fields, but it also defines additional nodes and fields specific to robotic definitions. For example, the Webots WorldInfo and Sphere nodes have additional fields with respect to VRML97.
This manual covers all the functions of the controller API, necessary to program robots. The C prototypes of these functions are described under the SYNOPSIS tag. The prototypes for the other languages are available through hyperlinks or directly in this chapter. The language-related particularities mentioned under the label called C++ Note, Java Note, Python Note, MATLAB Note, etc.
