opengl VC 请问如何实现在VC环境下,利用OPENGL实现屏幕图形的鼠标拖动 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 用glTranslate*()函数,把参数定义成变量,当鼠标移动的时候计算位移的改变,从而改变参数的值,就可以移动图形了 我有程序,给我发邮件我发给你![email protected] 在绘制要转的实物代码前加上: glRotated(X_Angle,1.0,0.0,0.0); glRotated(Y_Angle,0.0,1.0,0.0);其中X_Angle,Y_Angle分别是倾斜的情况,后面的坐标是转的中心。下面的代码分别是鼠标点下、鼠标移动、鼠标抬起的事件,以修改上面两个参数实现实物随鼠标旋转。void CGLDibTestView::OnLButtonDown(UINT nFlags, CPoint point) {// remember where we clicked MouseDownPoint=point;// capture mouse movements even outside window borders SetCapture();}void CGLDibTestView::OnLButtonUp(UINT nFlags, CPoint point) {// forget where we clicked MouseDownPoint=CPoint(0,0);// release mouse capture ReleaseCapture();}void CGLDibTestView::OnMouseMove(UINT nFlags, CPoint point) {// check if we have captured the mouse if (GetCapture()==this) {// increment the object rotation angles X_Angle+=double(point.y-MouseDownPoint.y)/3.6; Y_Angle+=double(point.x-MouseDownPoint.x)/3.6;// redraw the view Invalidate(TRUE);// remember the mouse point MouseDownPoint=point; };} VC下能不能查看串口DTR的状态? 没路了 大家来搭把手 谢谢 Cximage显示图片的某一部分 请问杀毒软件等软件向其它进程注入DLL的方法是什么? 菜鸟菜问,用MFC做的程序能不安装就到处用吗? [新人提问]关于鼠标点击分页对话框后,自动读取数据的问题 《Win32多线程程式设计》电子书哪有下载? 是否有办法禁止ie通过拨号上网?也就是说让ie只能通过局域网上网。 高手请进 解决不了的问题。求各位帮忙,斑竹救命!!! 怎样读取jpg文件中的Summary(作者、关键字、标题等)信息 程序运行到一段(3-5分钟)时间之后就死机了,只能重起。内详。
glRotated(X_Angle,1.0,0.0,0.0);
glRotated(Y_Angle,0.0,1.0,0.0);
其中X_Angle,Y_Angle分别是倾斜的情况,后面的坐标是转的中心。下面的代码分别是鼠标点下、鼠标移动、鼠标抬起的事件,以修改上面两个参数实现实物随鼠标旋转。void CGLDibTestView::OnLButtonDown(UINT nFlags, CPoint point)
{
// remember where we clicked
MouseDownPoint=point;
// capture mouse movements even outside window borders
SetCapture();
}void CGLDibTestView::OnLButtonUp(UINT nFlags, CPoint point)
{
// forget where we clicked
MouseDownPoint=CPoint(0,0);
// release mouse capture
ReleaseCapture();
}void CGLDibTestView::OnMouseMove(UINT nFlags, CPoint point)
{
// check if we have captured the mouse
if (GetCapture()==this)
{
// increment the object rotation angles
X_Angle+=double(point.y-MouseDownPoint.y)/3.6;
Y_Angle+=double(point.x-MouseDownPoint.x)/3.6;
// redraw the view
Invalidate(TRUE);
// remember the mouse point
MouseDownPoint=point;
};
