read() [1/2]

ModelPtr lvr2::AsciiIO::read ( string  filename )

virtual

Reads the given file and stores point and color information in the given parameters.

Parameters

filename

The file to read

Definition at line 227 of file AsciiIO.cpp.

read() [2/2]

ModelPtr lvr2::AsciiIO::read ( string  filename, const int &  x, const int &  y, const int &  z, const int &  r = -1, const int &  g = -1, const int &  b = -1, const int &  i = -1  )

virtual

read Parses the given file and stores point and color attribute information in the returned model pointer. It is assumed that the each line in the file (except the first one which may be a header line) contains point coordinates (x, y, z) and optional color and intensity information. The position (columns) of the supported attritbutes within each line are define by the respective parameters given to this function. Each line may consist of more attributes, but only the ones specified are parsed. Not existing attributes are indicated by -1.

Parameters

filename	The file to parse
x	The colum number containing the x-coordinate of a point
y	The colum number containing the y-coordinate of a point
z	The colum number containing the z-coordinate of a point
r	The colum number containing the r color component (or -1)
g	The colum number containing the g color component (or -1)
b	The colum number containing the b color component (or -1)
i	The colum number containing the intensity value (or -1)
