The text reader reads data from ASCII text files. Each point is represented in the file as a single line. Each line is expected to be divided into a number of fields by a separator. Each field represents a value for a point’s dimension. Each value needs to be formatted properly for C++ language double-precision values.
The text reader expects a header line to 1) indicate the separator character for the fields and 2) name the dimension for each field in the points. Any single non-alphanumeric character can be used as a separator. Each line in the file must contain the same number of fields as indicated by dimension names in the header. Spaces are generally ignored in the input unless used as a separator. When a space character is used as a separator, any number of consecutive spaces are treated as single space.
Blank lines after the header line are ignored.
This input file contains X, Y and Z value for 10 points.
