It can also be used to move critters in a realistic way.<p> libnoise is known to compile using the following compilers on the following platforms:<ul> <li>Microsoft Visual C++ 5.0 under Microsoft Windows 2000 Service Pack 4</li><li>gcc 3.3.4 under Gentoo Linux 10.0 (x86)</li></ul> <p> It is not known if libnoise will compile on 64-bit platforms, although there is a good change that it will.<h2><a class="anchor" name="noise"> Noise Modules</a></h2> In libnoise, coherent-noise generators are encapsulated in classes called <em>noise modules</em>. There are many different types of noise modules. Some noise modules can combine or modify the outputs of other noise modules in various ways; you can join these modules together to generate very complex coherent noise.<p> A noise module receives a 3-dimensional input value from the application, computes the noise value given that input value, and returns the resulting value back to the application.<p> If the application passes the same input value to a noise module, the noise module returns the same output value.<p> All noise modules are derived from the <a class="el" href="classnoise_1_1module_1_1Module.html">noise::module::Module</a> abstract base class.<h2><a class="anchor" name="contact"> Contact</a></h2> Contact jas for questions about libnoise.
