You simply provide vertices, and it will create as many meshes as necessary to contain them all.<p><dl compact><dt><b>Example:</b></dt><dd>This example produces a line strip with 10000 vertices. The factory is told to limit the number of vertices in a single primitive to 3000, so it will automatically produce four meshes with 3000, 3000, 3000, and 1000 vertices each. The meshes are automatically added to the indicated geometry node. <div class="fragment"><pre class="fragment"> { <a class="code" href="classvtGeom.html">vtGeom</a> *pLineGeom = <span class="keyword">new</span> <a class="code" href="classvtGeom.html">vtGeom</a>; <a class="code" href="classvtMeshFactory.html">vtMeshFactory</a> mf(pLineGeom, vtMesh::LINE_STRIP, 0, 3000, 1); mf.PrimStart(); <span class="keywordflow">for</span> (<span class="keywordtype">int</span> i = 0; i < 10000; i++) mf.AddVertex(<a class="codeRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/classFPoint3.html">FPoint3</a>(i,i,i)); mf.PrimEnd(); }</pre></div> </dd></dl><p><table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr><tr><td colspan="2"><br><h2>Public Member Functions</h2></td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtMeshFactory.html#ad29b7049512119a31cfd1f53ec5184e">vtMeshFactory</a> (<a class="el" href="classvtGeom.html">vtGeom</a> *pGeom, vtMeshBase::PrimType ePrimType, int iVertType, int iMaxVertsPerMesh, int iMatIndex, int iExpectedVerts=-1)</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtMeshFactory.html#37610f100693136e854b211c9d432537">vtMeshFactory</a> (<a class="el" href="classvtMesh.html">vtMesh</a> *pMesh)</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top">void </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtMeshFactory.html#32e57b1f3b786fde173c9e1eb0f067cd">PrimStart</a> ()</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top">void </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtMeshFactory.html#e0c31db5eecfd4f7c44245974a3dac32">AddVertex</a> (const <a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/classFPoint3.html">FPoint3</a> &p)</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top">void </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtMeshFactory.html#05e4d953a9e7250a45617bc7b3b8a77f">PrimEnd</a> ()</td></tr></table><hr><h2>Constructor & Destructor Documentation</h2><a class="anchor" name="ad29b7049512119a31cfd1f53ec5184e"></a><!-- doxytag: member="vtMeshFactory::vtMeshFactory" ref="ad29b7049512119a31cfd1f53ec5184e" args="(vtGeom *pGeom, vtMeshBase::PrimType ePrimType, int iVertType, int iMaxVertsPerMesh, int iMatIndex, int iExpectedVerts=-1)" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">vtMeshFactory::vtMeshFactory </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top"><a class="el" href="classvtGeom.html">vtGeom</a> * </td> <td class="mdname" nowrap> <em>pGeom</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>vtMeshBase::PrimType </td> <td class="mdname" nowrap> <em>ePrimType</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iVertType</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iMaxVertsPerMesh</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iMatIndex</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>iExpectedVerts</em> = <code>-1</code></td> </tr> <tr> <td class="md"></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p>Constructor.<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"></td><td valign="top"><em>pGeom</em> </td><td>The geometry node which will receive the mesh object(s) that this factory will produce. </td></tr> <tr><td valign="top"></td><td valign="top"><em>ePrimType</em> </td><td>The type of mesh to produce. </td></tr> <tr><td valign="top"></td><td valign="top"><em>iVertType</em> </td><td>The vertex attributes for the meshes to produce. </td></tr> <tr><td valign="top"></td><td valign="top"><em>iMaxVertsPerMesh</em> </td><td>The largest number of vertices to allow in a single mesh.
