Detailed Description

class used to link a LAS field defined by the LAS standard to the ACloudViewer scalar field that stores or will store the values.

Member Enumeration Documentation

◆ Id

enum LasScalarField::Id

Enum used to uniquely identify LAS fields with a clear distinction between 'normal' and 'extended' fields which may have the same name (e.g. Classification)

Member Function Documentation

◆ ForPointFormat()

std::vector< LasScalarField > LasScalarField::ForPointFormat ( unsigned pointFormatId )

static

Returns the scalar fields that correspond the the point format ID as per LAS specifications.

◆ IdFromName()

LasScalarField::Id LasScalarField::IdFromName	(	const char *	name,
		unsigned	targetPointFormat
	)

static

Returns the LasScalarField::Id variant that correspond to the given name

Point Format is needed, as we have different Id for the same name depending on the point format. For example: The "Classification" field has a different Id in fmt >= 6 as it allows to store more information.

Throws a logic_error if the name does not have a matching id
