opengl旋转和平移以绘制巨石阵

Question

我是openGL的新手，我的问题是当我执行旋转到Y轴时，函数glRotatef会产生错误的转换。我无法理解旋转功能是如何工作的，所以有人可以解释一下这个plis吗？

我的代码：

将每个弧放置到位：

void CreaStone(void)
{
    stone = glGenLists(1);
    if (stone != 0)
    {   int i = 0;
    int rotation = 15;
    float translationX = 2;
    float translationZ = 0;
    float fact = 0.2;
    glNewList(stone, GL_COMPILE);
    for(i = 0; i<5; ++i){
        /*Crear cada stone*/
        glPushMatrix();
        glScalef(0.15,0.15,0.15);
        glRotatef(rotation, 0,1,0);
        glTranslatef(translationX,0,0);
        arco();
        glPopMatrix();
        translationX = translationX + 2;
        //translationZ = translationZ + 1.8;
        fact += 0.2;
        rotation = rotation + 15;
    }

    glEndList();

    }

}

显示巨石阵元素组件

void arco(void)
{
    glPushMatrix();
    glScalef(0.25,0.6,0.25);
    glPushMatrix();
    glRotatef(45, 0, 2, 0);
    igWireCubo(4, 4);
    glPopMatrix();
    glPushMatrix();
    glRotatef(45, 0, 2, 0);
    glTranslatef(4,0,4);
    igWireCubo(4, 4);
    glPopMatrix();
    glPopMatrix();
    glPushMatrix();
    glScalef(1.250,0.20,0.25);
    glTranslatef(0,2,0);
    glTranslatef(0.566,0,0);
    glRotatef(45, 0, 2, 0);
    //glRotatef(90, 1, 0, 0);
    igWireCubo(4, 4);
    glPopMatrix();
}

绘制一个多维数据集

void igWireCubo(int pu, int pv)
{
    igCreateQuadricObject(pu, pv, 1.0f, 0.5f, 1.0f, 0.0f, 2.0f);
}

生成原始对象

void igCreateQuadricObject (int pu, int pv, float uMax, float vMax, float R, float s1, float s2)
{
    float u, v, inc_u, inc_v;
    float x, y, z;
    int   i,j;
    v= 0.0f;
    u = 0.0f;
    inc_u = uMax / pu;
    inc_v = vMax/ pv;

    for (i = 0; i <= pu; ++i) {

        glBegin(GL_LINE_LOOP);
        for (j = 0; j<= pu; ++j)
        {
            x = xSuperQuadric(u, v, R, s1, s2);
            y = ySuperQuadric(u, v, R, s1, s2);
            z = zSuperQuadric(u, v, R, s1, s2);
            glVertex3f(x, y, z);
            u = u + inc_u;}
        u = 0.0f;
        glEnd();
        v = v + inc_v;

    }

    v = 0.0f;
    u = 0.0f;

    for (i = 0; i <= pu; ++i) {

        glBegin(GL_LINE_STRIP);
        for (j = 0; j <= pv; ++j)
        {
            x = xSuperQuadric(u, v, R, s1, s2);
            y = ySuperQuadric(u, v, R, s1, s2);
            z = zSuperQuadric(u, v, R, s1, s2);
            glVertex3f(x, y, z);
            v = v + inc_v;

        }
        v = 0.0f;
        glEnd();
        u = u + inc_u;

    }

}
