<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkRandomAttributeGenerator is a filter that creates random attributes including scalars, vectors, normals, tensors, texture coordinates and/or general data arrays. These attributes can be generated as point data, cell data or general field data. The generation of each component is normalized between a user-specified minimum and maximum value.</p>
<p>This filter provides that capability to specify the data type of the attributes, the range for each of the components, and the number of components. Note, however, that this flexibility only goes so far because some attributes (e.g., normals, vectors and tensors) are fixed in the number of components, and in the case of normals and tensors, are constrained in the values that some of the components can take (i.e., normals have magnitude one, and tensors are symmetric).</p>
<p>To create an instance of class vtkRandomAttributeGenerator, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkRandomAttributeGenerator
</pre> <h1><a class="anchor" id="Methods"></a>
