<div class="refsect1" title="Description">
<a name="VisuRendering.description"></a><h2>Description</h2>
<p>
</p>
<p> The way visu renders its data is done by modules. They are
called rendering methods and they describes how data are drawn on
the screen. Many can be defined but only one is used at a time to
render the data.</p>
<p>
</p>
<p>
</p>
<p>One or more file type are associated with a rendering
method. And a rendering method must specify the way to load the
data it needs. Taking the example of a spin system representation,
there are two kinds of file. The first kind describes the position
the spin and the second contains their orientations.</p>
<p>
</p>
<p>
</p>
<p>To create a new rendering method, subclass
<a class="link" href="VisuRendering.html" title="VisuRendering"><span class="type">VisuRendering</span></a>. The name is mandatory and must be
unique. The description is not compulsory. The number of file kinds
is also required. Use <a href="v-sim-visu-rendering.html#renderingMethodSet-fileType"><code class="function">renderingMethodSet_fileType()</code></a> to associated a
<a href="/usr/share/gtk-doc/html/glib/glib-Doubly-Linked-Lists.html#GList"><span class="type">GList</span></a> of <a class="link" href="v-sim-toolFileFormat.html#ToolFileFormat" title="ToolFileFormat"><span class="type">ToolFileFormat</span></a>. In our example of spin system, the first
kind of file is about positions, and the associated file formats
are *.ascii, *.d3 and *.xyz.</p>
<p>
</p>
<p>
</p>
<p>The <a class="link" href="VisuRendering.html#VisuRendering-struct" title="VisuRendering"><span class="type">VisuRendering_struct</span></a> has to two pointers on methods
that are important. The first, <a href="v-sim-visu-rendering.html#createOpenGLElementFunc"><code class="function">createOpenGLElementFunc()</code></a> is called
when V_Sim needs to create an OpenGL list corresponding to the
<a class="link" href="v-sim-visu-elements.html#VisuElement"><span class="type">VisuElement</span></a> given as argument. This list then can be used to
render each node and thus accelerating the rendering
operations. The second method is <a href="v-sim-visu-rendering.html#createOpenGLNodeFunc"><code class="function">createOpenGLNodeFunc()</code></a> and is
called by V_Sim for each node of the system when the main OpenGL
list (the one for the nodes) is created. Thus, in the contrary of
the first method, thios one should not create an OpenGL list but
directly call OpenGL routines to draw the node. This method is also
responsible to put the node at the right position. Use
<a class="link" href="v-sim-visu-data.html#visu-data-getNodePosition" title="visu_data_getNodePosition ()"><code class="function">visu_data_getNodePosition()</code></a> to retrieve the position and translate
the node accordingly.</p>

This is an interface for a generic load method. This method read the file
positionned on <em class="parameter"><code>filename</code></em> and populate or change the arrays in
<em class="parameter"><code>data</code></em>. When enter this method, the <em class="parameter"><code>data</code></em> argument is already
allocated but its arrays may be empty and unallocated (depending on
context). If the load method fails (because the format is wrong or
anything else), the <em class="parameter"><code>data</code></em> argument should not be modified. If some
errors occur, the pointer <em class="parameter"><code>error</code></em> will be instanciated. A

specific set of nodes if the input format supports it. If <em class="parameter"><code>nSet</code></em> is
0, then the default set of nodes is loaded.
