64位系统运行nehe opengl

Question

我按照网上下载的nehe sdk进行配置以后，运行以后不出现opengl的窗口。
但使用网上另外一段opengl代码就运行成功了，不知道是不是因为64位系统的问题，用的是systemwow64文件夹存放dll。

Answer 1

#include "opengl.h"
#include "view.h"
using namespace NeHe;
// the view class
static View view;

static GLfloat rtri; // Angle For The Triangle

static GLfloat rquad; // Angle For The Quad

void DrawScene(OpenGL *gl,ControlData *cont)
{

view.Reset();

view.Translate(-1.5f,0.0f,-6.0f); // Move Left 1.5 Units And Into The Screen 6.0

view.Rotate(rtri,0.0f,1.0f,0.0f); // Rotate The Triangle On The Y axis

}
这是网上给的nehe opengl代码，运行不能显示窗口。
