Model that defines the surface of a cylinder.
<p>
<div align="center">
<img src="modelcylinder.png" alt="modelcylinder.png">
</div>
<p>
This model returns an output value from a noise module given the coordinates of an input value located on the surface of a cylinder.<p>
To generate an output value, pass the (angle, height) coordinates of an input value to the <a class="el" href="classnoise_1_1model_1_1Cylinder.html#a3">GetValue()</a> method.<p>
This model is useful for creating:<ul>
<li>seamless textures that can be mapped onto a cylinder</li></ul>
<p>
This cylinder has a radius of 1.0 unit and has infinite height. It is oriented along the <em>y</em> axis. Its center is located at the origin.
