Detailed Description

Read ASCII or binary particle data and (optionally) one scalar value associated with each particle.

vtkParticleReader reads either a binary or a text file of particles. Each particle can have associated with it an optional scalar value. So the format is: x, y, z, scalar (all floats or doubles). The text file can consist of a comma delimited set of values. In most cases vtkParticleReader can automatically determine whether the file is text or binary. The data can be either float or double. Progress updates are provided. With respect to binary files, random access into the file to read pieces is supported.

◆ SetDataByteOrderToBigEndian()

void vtkParticleReader::SetDataByteOrderToBigEndian ( )

These methods should be used instead of the SwapBytes methods.

They indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. As a quick note most UNIX machines are BigEndian while PC's and VAX tend to be LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetDataByteOrderToLittleEndian otherwise SetDataByteOrderToBigEndian. Not used when reading text files.

◆ ProduceOutputFromTextFileDouble()

int vtkParticleReader::ProduceOutputFromTextFileDouble ( vtkInformationVector outputVector)
protected

The format that will be read if the file is a text file is: x, y, z, s (where s is some scalar value associated with the particle).

Each line corresponding to a particle is terminated with a line feed. If y, z, or s is missing, zero is substituted for them. Comment lines in the file are handled as follows: 1) Any line containing "\/\/" "\#" "\%" anywhere in the line is discarded. 2) Lines containing "\/\*" are discarded until a "\*\/" is found. The line following the "\*\/" will be read.

◆ ProduceOutputFromTextFileFloat()

int vtkParticleReader::ProduceOutputFromTextFileFloat ( vtkInformationVector outputVector)

The format that will be read if the file is a text file is: x, y, z, s (where s is some scalar value associated with the particle).

The line following the "\*\/" will be read.

◆ ProduceOutputFromBinaryFileDouble()

int vtkParticleReader::ProduceOutputFromBinaryFileDouble ( vtkInformationVector outputVector)
protected

This reader assumes that the file is binary and consists of floating point values by default.

protected

This reader assumes that the file is binary and consists of floating point values by default.

◆ DetermineFileType()

int vtkParticleReader::DetermineFileType ( )
protected

Determine the type of file based on an analysis of its contents.

Up to 5000 bytes of the file are read and classified. The classification of a file as either binary or text is based on the proportions of bytes in various classifications. The classification of the file is not infallible but should work correctly most of the time. If it fails, use SetFileTypeToText() or SetFileTypeToBinary() to set the file type. This algorithm probably only identifies ASCII text correctly and will not work for UTF-8 UCS-2 (or UTF-16) or UCS-4 or EBCIDIC.

◆ DoProgressUpdate()

void vtkParticleReader::DoProgressUpdate ( size_t &  bytesRead,
size_t &  fileLength 
)
protected
