Member Function Documentation

QString NormalRenderer::description ( )

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 74 of file NormalRenderer.hh.

QString NormalRenderer::name ( )

Return a name for the plugin.

This Function has to return the name of the plugin.

Implements BaseInterface.

Definition at line 73 of file NormalRenderer.hh.

QString NormalRenderer::renderObjectsInfo ( bool  _outputShaderInfo)

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.

_outputShaderInfoOutput shader code along with the render objects
string of render objects

Reimplemented from RenderInterface.
