Detailed Description

This class manages the properties required for creating Buffers from a DataFrame dataset. In particular, it allows to select specific columns to be used for vertex data, normals, colors, etc. Data values can also be transformed.

getBuffers()

Mesh::BufferVector inviwo::util::ColumnMapper::getBuffers

(

const DataFrame &

df

)

Generate mesh buffers for the given DataFrame set df based on the internal properties.

Parameters

df	DataFrame used as data source

isModified()

bool inviwo::util::ColumnMapper::isModified

(

)

const

Query the isModified() status of all nested composite properties

Returns

true if any of the composite info properties is modified

updateSources()

void inviwo::util::ColumnMapper::updateSources

(

const DataFrame &

df

)

Update the internal state to match the DataFrame columns of df and their names.

Parameters
