extract components of vector as separate scalars
<p>
<a class="el" href="a00526.html" title="extract components of vector as separate scalars">vtkExtractVectorComponents</a> is a filter that extracts vector components as separate scalars. This is accomplished by creating three different outputs. Each output is the same as the input, except that the scalar values will be one of the three components of the vector. These can be found in the VxComponent, VyComponent, and VzComponent. Alternatively, if the ExtractToFieldData flag is set, the filter will put all the components in the field data. The first component will be the scalar and the others will be non-attribute arrays.<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>This filter is unusual in that it creates multiple outputs. If you use the <a class="el" href="a00375.html#1475d7c525c459ee9ff6a72f04a15f8d">GetOutput()</a> method, you will be retrieving the x vector component.</dd></dl>

Get the output dataset representing velocity z-component. If output is NULL then input hasn't been set, which is necessary for abstract objects. (Note: this method returns the same information as the <a class="el" href="a00375.html#1475d7c525c459ee9ff6a72f04a15f8d">GetOutput()</a> method with an index of 2.) Note that if ExtractToFieldData is true, this output will be empty.
