Opengl鼠标旋转问题

Question

当我点击鼠标时，我的图形可以旋转，但是当我用鼠标将图形转回初始位置时，我不知道为什么这是我的事件

这是关于我的问题的插图

我觉得跟在图片框上移动完全不一样

Mouse_up 事件

 private void simpleOpenGlControl1_MouseUp(object sender, MouseEventArgs e)
        {
            Dragging2 = false;
        }


 private void simpleOpenGlControl1_MouseMove(object sender, MouseEventArgs e)
        {
            xrot -= 0.5;
            simpleOpenGlControl1.Refresh();

        }

Mouse_down 事件

        {
            
            if (e.Button == MouseButtons.Left)
            {
                    Dragging2 = true;
            }
           
        }

            double olcek3d_gen1 = obj.genislikDeger1 / pictureBox1.Width;
            double olcek3d_gen2 = obj.genislikDeger2 / pictureBox1.Width;
            double olcek3d_gen3 = obj.genislikDeger3 / pictureBox1.Width;
            double olcek3d_gen4 = obj.genislikDeger4 / pictureBox1.Width;

            double olcek3d_yuk1 = obj.yukselikDeger1 / pictureBox1.Width;
            double olcek3d_yuk2 = obj.yukselikDeger2 / pictureBox1.Width;
            double olcek3d_yuk3 = obj.yukselikDeger3 / pictureBox1.Width;
            double olcek3d_yuk4 = obj.yukselikDeger4 / pictureBox1.Width;

Answer 1

因为您仅在 Dragging2 处于活动状态时才应用 xrot 旋转...您应该在每一帧执行此操作，或者在鼠标向上时将最终旋转应用于用于初始化的某些初始矩阵框架开始时的模型视图而不是标识

所以最简单的就是改：

if (Dragging2)
    {
    Gl.glRotated(xrot, xRotate, yRotate, zRotate);
    listBox1.Items.Add("angle  " + xrot.ToString() +"  xrot  "+ xRotate+"  yrot  "+ yRotate+"  zrot  "+zRotate+"  left_right  "+left_right+"  up_Down  "+ up_down);
    }

进入：

Gl.glRotated(xrot, xRotate, yRotate, zRotate);
if (Dragging2)
    {
    listBox1.Items.Add("angle  " + xrot.ToString() +"  xrot  "+ xRotate+"  yrot  "+ yRotate+"  zrot  "+zRotate+"  left_right  "+left_right+"  up_Down  "+ up_down);
    }

不确定列表框的用途（或者它是否没有内存泄漏...）。但是，如果您的 xRotate, yRotate, zRotate 发生变化，那么您需要实施初始累积矩阵 ...
