C++ 向量存储器，不需要的0和x27的向量；s

我的代码适用于我的纯glut实现，但我正在尝试让它在qt中工作

我有一个金属丝网系统的质量点向量

std::vector<masspoint> m_particles; 

std:：向量m_粒子；

问题是在我的qt版本中，我写的东西没有一个真正的坚持，我只剩下一个零数组。基本上我不明白为什么glut版本有正确的值，而qt版本没有给出基本相同的代码。qt代码有什么问题

是的，我在使用qDebug时只看到零。当我在qt版本中调用绘图函数时，所有组件中的所有顶点都是0，因此看不到任何东西

int myboog = 1;
int county = 0;
// Constructors
Cloth::Cloth(float width, float height, int particles_in_width, int particles_in_height):
m_width(particles_in_width),
m_height(particles_in_height),
m_dimensionWidth(width),
m_dimensionHeight(height),
m_distanceX(width/(float)particles_in_width),
m_distanceY(height/(float)particles_in_height)
{

    //Set the particle array to the given size
    //Height by width

    //mparticles is the name of our vector
    m_particles.resize(m_width*m_height);
    qDebug() << m_particles.size();

    // Create the point masses to simulate the cloth
    for (int x = 0; x < m_width; ++x)
    {
        for (int y=0; y < m_height; ++y)
        {
            // Place the pointmass of the cloth, lift the edges to give the wind more effect as the cloth falls
            Vector3f position = Vector3f(m_dimensionWidth * (x / (float)m_width),
                                         ((x==0)||(x==m_width-1)||(y==0)||(y==m_height-1)) ? m_distanceY/2.0f:0,
                                         m_dimensionHeight * (y / (float)m_height));

            // The gravity effect is applied to new pmasspoints
            m_particles[y * m_width + x] = masspoint(position,Vector3f(0,-0.06,0));

        }

    }

    int num = (int)m_particles.size();
    for (int i=0; i<num; ++i)
    {
        masspoint* p = &m_particles[i];
        if(myboog)
        {
            qDebug() << "test " <<  *p->getPosition().getXLocation() << county;
            county++;
        }
    }
    myboog = 0;

    // Calculate the normals for the first time so the initial draw is correctly lit
    calculateClothNormals();
}

int myboog=1；
int县=0；
//建设者
Cloth:：Cloth（浮动宽度、浮动高度、整数粒子\u英寸宽度、整数粒子\u英寸高度）：
m_宽度（粒子的宽度），
m_高度（粒子在高度中），
m_尺寸宽度（宽度），
m_尺寸高度（高度），
m_距离x（宽度/（浮动）粒子的宽度），
m_距离（高度/（浮动）粒子的高度）
{
//将粒子阵列设置为给定大小
//宽高
//mparticles是向量的名称
m_粒子。调整大小（m_宽度*m_高度）；
qDebug（）所以qDebug（）是的，我刚刚添加了qt，因为它完全适用于glut，但现在在qt中，我只得到0。
