## Member Function Documentation

## ◆ description() [1/2]

QString Renderer::description | ( |  | ) |
| inline virtual

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 75 of file Renderer.hh.

## ◆ description() [2/2]

QString Renderer::description | ( |  | ) |
| inline virtual

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 83 of file Renderer.hh.

## ◆ name() [1/2]

QString Renderer::name | ( |  | ) |
| inline virtual

Return a name for the plugin.

This Function has to return the name of the plugin.

Implements BaseInterface.

Definition at line 74 of file Renderer.hh.

## ◆ name() [2/2]

QString Renderer::name | ( |  | ) |
| inline virtual

Return a name for the plugin.

This Function has to return the name of the plugin.

Implements BaseInterface.

Definition at line 82 of file Renderer.hh.

## ◆ renderObjectsInfo()

QString Renderer::renderObjectsInfo | ( | bool | _outputShaderInfo | ) |
| inline 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.
