c – 如何在opengl中以y轴或x轴绘制圆柱体

我只想在opengl中绘制一个圆柱体.我找到了很多样本​​但是所有样本都在z轴上绘制了圆柱体.我希望它们在x或y轴上.我怎样才能做到这一点.下面的代码是代码在z方向绘制圆柱体,我不想要它

gluquadricObj *quadratic;
  quadratic = gluNewQuadric();
  gluCylinder(quadratic,0.1f,3.0f,32,32);

解决方法

您可以使用glrotate(angle,x,y,z)来旋转坐标系：

gluquadricObj *quadratic;
quadratic = gluNewQuadric();
glrotatef(90.0f,0.0f,1.0f,0.0f);
gluCylinder(quadratic,32);
