Detailed Description

Class with the logic on how to load LAS dimensions values from the LAS file into a ccPointCloud's scalar field.

This also handles LAS extra scalar fields, as well as RGB.

handleRGBValue()

CC_FILE_ERROR LasScalarFieldLoader::handleRGBValue	(	ccPointCloud &	pointCloud,

In LAS files, the red, green and blue channels are normal LAS fields, however in ACloudViewer RGB is handled differently.
