Member Function Documentation

◆ description()

QString DepthPeeling::description ( )

inlinevirtual

Return a description of what the plugin is doing.

This function has to return a basic description of the plugin

Implements BaseInterface.

Definition at line 78 of file DepthPeeling.hh.

◆ name()

QString DepthPeeling::name ( )

inlinevirtual

Return a name for the plugin.

This Function has to return the name of the plugin.

Implements BaseInterface.

Definition at line 77 of file DepthPeeling.hh.

◆ optionsAction()

QAction * DepthPeeling::optionsAction ( )

virtual

Return options menu.

If you want an options Menu or menu entry, you can return your action here. It will be shown on top of the renderer list in the options menu.

Returns: Action for a menu or menu entry

Reimplemented from RenderInterface.

Definition at line 53 of file DepthPeeling_qt.cc.

◆ renderObjectsInfo()

QString DepthPeeling::renderObjectsInfo ( bool _outputShaderInfo )

virtual

Return a qstring of the current render objects.

In this function your plugin should return a list of the render objects (possibly with additional information). It can be used for debugging purposes.

The IRenderer class already has a function called dumpCurrentRenderObjectsToString() which can be used to implement this function.

Parameters

_outputShaderInfo Output shader code along with the render objects

Returns: string of render objects

Reimplemented from RenderInterface.

Definition at line 1080 of file DepthPeeling.cc.
