# Viewports

A ViewPort represents the 3D viewport where Mudbox renders the scene. The ViewPort derives from LayerContainer. Note that a ViewPortFilter derives from a Layer, so the primary role of the ViewPort is to manage ViewPortFilter effects.

In addition to managing ViewPortFilters (and Layers) the following functions are provided:

- ViewPort::Width()
- ViewPort::Height()
- ViewPort::SaveScreenshot()
- ViewPort::ViewPortFilterRequirements()
