在Win32api中嵌入glut应用程序 [英] embedding glut application in win32api

问题描述

我仅使用平台库在win32中完成了opengl应用程序.
它执行得非常慢，所以我决定使用glut库来执行相同的opengl项目

opengl代码在glut情况下可以正常工作，但在win32中却不能.
我以为那是因为wm-paint，所以我用定时器做到了，但什至没有效果
使用像素结构播放.


因此，如何在win32中集成opengl代码而又不损失性能

i have done a opengl application in win32 only using platform library.
it was performing very slow so i decided to do the same opengl project using glut library

opengl code workes fine in glut but not in win32.

i thought it would be because of wm-paint so i did it with timer but no effect even
played with pixel struct.


so how can i integrate opengl code in win32 without loss in performance

推荐答案

绘制框架后，请调用:: ValidateRect(m_hRenderingWindow，0);相应窗口的. m_hRenderingWindow是绘制opengl场景的窗口.给出0以避免整个区域在下一次更新.

请尝试这样:

After drawing a frame, please call ::ValidateRect( m_hRenderingWindow, 0 ); of the corresponding Window. m_hRenderingWindow is the window where you drawing opengl scene. 0 is given to avoid the entire region from updating on next time.

Please try like this:

LRESULT CALLBACK WindowProc( HWND   hWnd, 
							 UINT   msg, 
							 WPARAM wParam, 
							 LPARAM lParam )
switch( msg )
	{
        case WM_PAINT:
	{
....  
RenderScene(); // Prepares your sence.

ValidateRect( m_hRenderWindow, 0 ); // Specifies that entire region of window should be avoided from update region.
	}
.....
}
