Detailed Description

Draw a simplex mesh including visual options.

For drawing the mesh, mesh surface, current state and the mesh winding can be displayed.

Example

#include <d3tessdraw.h>

mesh = new d3tess(N);
d3tessdraw *meshdraw = new d3tessdraw(*mesh);

meshdraw->graphicsDeffered.vi[d3tessdraw::multicolor]->isdrawn = true;
meshdraw->graphicsDeffered.vi[d3tessdraw::points]->isdrawn = true;
meshdraw->graphicsDeffered.vi[d3tessdraw::simplexes]->isdrawn = true;

meshdraw->meshupdate();
