visu_plugins Introduces the basic handling of plug-ins. Plug-ins are made of shared library presenting some common routines. These routines are of kind: pluginsInitFunc(), such a routine is called at V_Sim startup. It should initialise all things required by the module. For instance, if the module is used to add a load method for atomic rendering, it should call renderingAtomicAdd_loadMethod() to declare itself to V_Sim. pluginsDescriptionFunc(), is used to get a short description of the plug-in. pluginsAuthorsFunc(), gives a list of authors for the plug-in. pluginsIconFunc(), returns a path where a small icon representing the plug-in can be found. All these routines must be named using the name of the module. When the module is loaded into memory, V_Sim will try to find these methods and will store them into the #VisuPlugin structure for future calls. At the present time, only the Unix version is functional. Moreover, currently, no stable API is available from the main program. This should be corrected quickly. @hook: @name: @init: @getDescription: @getAuthors: @getIcon: @Returns: @Returns: @Returns: @Returns: @Returns:
