<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkMCubesReader is a source object that reads binary marching cubes files. (Marching cubes is an isosurfacing technique that generates many triangles.) The binary format is supported by W. Lorensen's marching cubes program (and the vtkSliceCubes object). The format repeats point coordinates, so this object will merge the points with a vtkLocator object. You can choose to supply the vtkLocator or use the default.</p>
<p>To create an instance of class vtkMCubesReader, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkMCubesReader
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkMCubesReader has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, <code>obj</code> is an instance of the vtkMCubesReader class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkMCubesReader = obj.NewInstance ()</code> </li>
<li>
<code>vtkMCubesReader = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>obj.SetFileName (string )</code> - Specify file name of marching cubes file. </li>
<li>
<code>string = obj.GetFileName ()</code> - Specify file name of marching cubes file. </li>
<li>
<code>obj.SetLimitsFileName (string )</code> - Set / get the file name of the marching cubes limits file. </li>
<li>
<code>string = obj.GetLimitsFileName ()</code> - Set / get the file name of the marching cubes limits file. </li>
<li>
<code>obj.SetHeaderSize (int )</code> - Specify a header size if one exists. The header is skipped and not used at this time. </li>
<li>
<code>int = obj.GetHeaderSizeMinValue ()</code> - Specify a header size if one exists. The header is skipped and not used at this time. </li>
<li>
<code>int = obj.GetHeaderSizeMaxValue ()</code> - Specify a header size if one exists. The header is skipped and not used at this time. </li>
<li>
<code>int = obj.GetHeaderSize ()</code> - Specify a header size if one exists. The header is skipped and not used at this time. </li>
<li>
<code>obj.SetFlipNormals (int )</code> - Specify whether to flip normals in opposite direction. Flipping ONLY changes the direction of the normal vector. Contrast this with flipping in vtkPolyDataNormals which flips both the normal and the cell point order. </li>
<li>
<code>int = obj.GetFlipNormals ()</code> - Specify whether to flip normals in opposite direction. Flipping ONLY changes the direction of the normal vector. Contrast this with flipping in vtkPolyDataNormals which flips both the normal and the cell point order. </li>
<li>
<code>obj.FlipNormalsOn ()</code> - Specify whether to flip normals in opposite direction. Flipping ONLY changes the direction of the normal vector. Contrast this with flipping in vtkPolyDataNormals which flips both the normal and the cell point order. </li>
<li>
<code>obj.FlipNormalsOff ()</code> - Specify whether to flip normals in opposite direction. Flipping ONLY changes the direction of the normal vector. Contrast this with flipping in vtkPolyDataNormals which flips both the normal and the cell point order. </li>
<li>
<code>obj.SetNormals (int )</code> - Specify whether to read normals. </li>
<li>
<code>int = obj.GetNormals ()</code> - Specify whether to read normals. </li>
<li>
<code>obj.NormalsOn ()</code> - Specify whether to read normals. </li>
<li>
<code>obj.NormalsOff ()</code> - Specify whether to read normals. </li>
<li>
<code>obj.SetDataByteOrderToBigEndian ()</code> - 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. </li>
<li>
<code>obj.SetDataByteOrderToLittleEndian ()</code> - 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. </li>
<li>
<code>int = obj.GetDataByteOrder ()</code> - 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. </li>
<li>
<code>obj.SetDataByteOrder (int )</code> - 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.

So if the file you are reading in was generated on a VAX or PC, SetDataByteOrderToLittleEndian otherwise SetDataByteOrderToBigEndian. </li>
<li>
<code>string = obj.GetDataByteOrderAsString ()</code> - 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. </li>
<li>
<code>obj.SetSwapBytes (int )</code> - Turn on/off byte swapping. </li>
<li>
<code>int = obj.GetSwapBytes ()</code> - Turn on/off byte swapping. </li>
<li>
<code>obj.SwapBytesOn ()</code> - Turn on/off byte swapping. </li>
<li>
<code>obj.SwapBytesOff ()</code> - Turn on/off byte swapping. </li>
<li>
<code>obj.SetLocator (vtkIncrementalPointLocator locator)</code> - Set / get a spatial locator for merging points. By default, an instance of vtkMergePoints is used. </li>
<li>
<code>vtkIncrementalPointLocator = obj.GetLocator ()</code> - Set / get a spatial locator for merging points. By default, an instance of vtkMergePoints is used. </li>
<li>
<code>obj.CreateDefaultLocator ()</code> - Create default locator. Used to create one when none is specified. </li>
<li>
<code>long = obj.GetMTime ()</code> - Return the mtime also considering the locator. </li>
