# 4.0 Call Back Reference

Description

The Callback Reference contains descriptions of those functions that formZ calls, and that a plugin or script "fills in" with the algorithm to perform the task at hand. That is, formZ asks each extension to do certain tasks, and the callback functions provide the functionality behind those tasks. For example, formZ will ask a renderer plugin to "render" the scene by calling the plugin renderer's callback function fz_rndr_cbak_image_disp. The plugin renderer is in charge of supplying the functionality of what it means to render the scene. Or formZ may ask the renderer to do something as simple as providing its name, by calling the renderer's fz_rndr_cbak_name callback function.
