Achieving PostScript and Wmf outputs for OpenGL

, 9 Jun 2003
This article explains how to generate resolution independent versions of 3D meshes rendered by OpenGL/MFC programs, i.e. how to export the rendering results to vectorial formats such as encapsulated postscript (EPS) and Windows enhanced metafile (EMF) formats. The main goal consists of being able to
// Array3d.h
// class CArray3d
// Created : 30/01/98
// Modified : 11/03/98

#include "stdafx.h"
#include "Array3d.h"

// FreeExtra
template<class T>
void CArray3d<T>::FreeExtra()

	if (m_nSize != m_nMaxSize)
		// shrink to desired size
#ifdef SIZE_T_MAX
		ASSERT(m_nSize <= SIZE_T_MAX/sizeof(T*));
		T** pNewData = NULL;
		if (m_nSize != 0)
			pNewData = (T**) new BYTE[m_nSize * sizeof(T*)];
			// copy new data from old
			memcpy(pNewData, m_pData, m_nSize * sizeof(T*));

		// get rid of old stuff (note: no destructors called)
		delete[] (BYTE*)m_pData;
		m_pData = pNewData;
		m_nMaxSize = m_nSize;
