TIN, a 'triangulated irregular network'. A TIN consists of a set of vertices connected by triangles with no regularity. However this class does expect to operate on a particular kind of TIN, specifically a heightfield TIN.<p>The triangles are defined by indices into the vertex array, so this is an "indexed TIN". <p><hr><h2>Member Function Documentation</h2><a class="anchor" name="69ea7b125d03a4017e92f9ead7334c7d"></a><!-- doxytag: member="vtTin::CleanupClockwisdom" ref="69ea7b125d03a4017e92f9ead7334c7d" args="()" --><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">void vtTin::CleanupClockwisdom </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top"> ) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td>⌨️ 快捷键说明
