<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkProperty is an object that represents lighting and other surface properties of a geometric object. The primary properties that can be set are colors (overall, ambient, diffuse, specular, and edge color); specular power; opacity of the object; the representation of the object (points, wireframe, or surface); and the shading method to be used (flat, Gouraud, and Phong). Also, some special graphics features like backface properties can be set and manipulated with this object.</p>
<p>To create an instance of class vtkProperty, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkProperty
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkProperty 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 vtkProperty class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>

<li>
<code>obj.BackfaceRender (vtkActor , vtkRenderer )</code> - This method renders the property as a backface property. TwoSidedLighting must be turned off to see any backface properties.
