## Module: AutoExtractXSection (
)

### Description:

> This is an experimental module from the Xtra Library: https://xtras.amira-avizo.com.

> "Surface Cross Section" module is currently able to show just opaque surfaces and requires user interaction to export capping surfaces. Thanks to the auto-refresh feature, this "Python script object" can update and show a partially transparent surface capping the original one. The capping surface is evaluated and updated as soon as any of the ports of the referenced "Surface Cross Section" is changed. Of course this module can be exploited to create nicer animations.

### Connections:

> Reference `[required]`
> It is the "Surface cross section" used to create the capping surface. This module must have its data port set to a Surface data and the "clip" plane must be active. Finally, its viewer toggle must be off (not visible) to avoid possible z-fighting issues when showing the transparent capping surface.

### Ports:

> Console
> Shows the Python script console.

> Base Trans
> It is the base transparency (alpha) value used to render the capping surface. Its value must be the same of the same named port of the "Surface view" used to display the whole/clipped surface.
