Detailed Description

write vtkDataSet using a vtkArchiver with a JSON meta file along with all the binary arrays written as standalone binary files.

The generated format can be used by vtk.js using the reader below https://kitware.github.io/vtk-js/examples/HttpDataSetReader.html

vtkJSONDataSetWriter writes vtkImageData / vtkPolyData into a set of files representing each arrays that compose the dataset along with a JSON meta file that describe what they are and how they should be assembled into an actual vtkDataSet.

Warning
This writer assume LittleEndian by default. Additional work should be done to properly handle endianness.

Member Function Documentation

◆ ComputeMD5()

static void vtkJSONDataSetWriter::ComputeMD5 ( const unsigned char *  content,
int  size,
std::string &  hash 
)
static

Compute a MD5 digest of a void/(const unsigned char) pointer to compute a string hash.

◆ GetShortType()

static std::string vtkJSONDataSetWriter::GetShortType ( vtkDataArray input,
bool &  needConversion 
)
static

Compute the target JavaScript typed array name for the given vtkDataArray (Uin8, Uint16, Uin32, Int8, Int16, Int32, Float32, Float64) or "xxx" if no match found.

Since Uint64 and Int64 does not exist in JavaScript, the needConversion argument will be set to true and Uint32/Int32 will be returned instead.

◆ GetUID()

static std::string vtkJSONDataSetWriter::GetUID ( vtkDataArray ,
bool &  needConversion 
)
static

Return a Unique identifier for that array (i.e.: Float32_356_13f880891af7b77262c49cae09a41e28 )

◆ GetValidString()

std::string vtkJSONDataSetWriter::GetValidString ( const char *  )

Return a Unique identifier for any invalid string.

◆ WriteArrayContents()

bool vtkJSONDataSetWriter::WriteArrayContents ( vtkDataArray ,
VTK_FILEPATH const char *  relativeFilePath 
)

Write the contents of the vtkDataArray to disk based on the filePath provided without any extra information.

Just the raw data will be written.

If vtkDataArray is a Uint64 or Int64, the data will be converted to Uint32 or Int32 before being written.

◆ WriteArrayAsRAW()

static bool vtkJSONDataSetWriter::WriteArrayAsRAW ( vtkDataArray ,
VTK_FILEPATH const char *  filePath 
)
static

For backwards compatiblity, this static method writes a data array's contents directly to a file.

◆ New()

static vtkJSONDataSetWriter * vtkJSONDataSetWriter::New ( )
static

◆ IsTypeOf()

static vtkTypeBool vtkJSONDataSetWriter::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkJSONDataSetWriter::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkWriter.

◆ SafeDownCast()

static vtkJSONDataSetWriter * vtkJSONDataSetWriter::SafeDownCast ( vtkObjectBase o)
static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkJSONDataSetWriter::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkWriter.

◆ NewInstance()

vtkJSONDataSetWriter * vtkJSONDataSetWriter::NewInstance ( ) const

◆ PrintSelf()

void vtkJSONDataSetWriter::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkWriter.

◆ SetFileName()

void vtkJSONDataSetWriter::SetFileName ( VTK_FILEPATH const char *  )

Specify file name of vtk data file to write.

This correspond to the root directory of the data to write. DEPRECATED: use the Archive's API instead.

◆ GetFileName()

virtual VTK_FILEPATH char * vtkJSONDataSetWriter::GetFileName ( )
virtual

Specify file name of vtk data file to write.

This correspond to the root directory of the data to write. DEPRECATED: use the Archive's API instead.

◆ GetInput() [1/2]

vtkDataSet * vtkJSONDataSetWriter::GetInput ( )

Get the input to this writer.

◆ GetInput() [2/2]

vtkDataSet * vtkJSONDataSetWriter::GetInput ( int  port)

Get the input to this writer.

◆ SetArchiver()

virtual void vtkJSONDataSetWriter::SetArchiver ( vtkArchiver )
virtual

Specify the Scene Archiver object.

◆ GetArchiver()

virtual vtkArchiver * vtkJSONDataSetWriter::GetArchiver ( )
virtual

Specify the Scene Archiver object.

◆ Write() [1/2]

void vtkJSONDataSetWriter::Write ( vtkDataSet )

◆ IsDataSetValid()

bool vtkJSONDataSetWriter::IsDataSetValid ( )
inline

◆ WriteData()

void vtkJSONDataSetWriter::WriteData ( )
finalprotectedvirtual

Implements vtkWriter.

◆ WriteArray()

std::string vtkJSONDataSetWriter::WriteArray ( vtkDataArray ,
const char *  className,
const char *  arrayName = nullptr 
)
protected

◆ WriteDataSetAttributes()

std::string vtkJSONDataSetWriter::WriteDataSetAttributes ( vtkDataSetAttributes fields,
const char *  className 
)
protected

◆ FillInputPortInformation()

int vtkJSONDataSetWriter::FillInputPortInformation ( int  port,
vtkInformation info 
)
overrideprotectedvirtual

Fill the input port information objects for this algorithm.

This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.

◆ Write() [2/2]

virtual int vtkWriter::Write ( )
virtual

Write data to output.

Method executes subclasses WriteData() method, as well as StartMethod() and EndMethod() methods. Returns 1 on success and 0 on failure.

Reimplemented from vtkWriter.
