Directx11教程(58) 鼠标控制摄像机
本篇教程我们实现鼠标旋转摄像机的操作。主要就是按下鼠标左键的时候，根据鼠标的移动对摄像机进行pitch, raw的组合旋转。具体修改代码是在D3CClass类中，增加对鼠标事件的处理：
case WM_LBUTTONDOWN:
if( wparam & MK_LBUTTON )
{
SetCapture(hwnd);
m_OldMousePos.x = LOWORD(lparam);
m_OldMousePos.y = HIWORD(lparam);
}
return 0;
case WM_LBUTTONUP:
ReleaseCapture();
return 0;
case WM_MOUSEMOVE:
if( wparam & MK_LBUTTON )
{
mousePos.x = (int)LOWORD(lparam);
mousePos.y = (int)HIWORD(lparam);
dx = mousePos.x - m_OldMousePos.x;
dy = mousePos.y - m_OldMousePos.y;
//通过鼠标转动摄像机
m_Graphics->m_Camera->pitch(dy * 0.0087266f);
m_Graphics->m_Camera->yaw(dx * 0.0087266f);
m_OldMousePos = mousePos;
}
return 0;
