====== OpenGL auf Windows ======

Das Plattform SDK kommt leider nur mit Headern für eine veraltete OpenGL Version.

===== Init-Möglichkeit =====

<code cpp>
bool initGL()
{
PIXELFORMATDESCRIPTOR pfd;
HWND hwnd; HDC hdc; int pixelFormat;
memset(&pfd,0,sizeof(PIXELFORMATDESCRIPTOR));
pfd.nSize = sizeof(PIXELFORMATDESCRIPTOR);
pfd.nVersion = 1;
pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER;
pfd.iPixelType = PFD_TYPE_RGBA;
pfd.cColorBits = 32;
pfd.cDepthBits = 16;
pfd.iLayerType = PFD_MAIN_PLANE;

hwnd = CreateWindowEx(WS_EX_TOOLWINDOW,"STATIC","glctx",
WS_POPUP|WS_CLIPSIBLINGS | WS_CLIPCHILDREN | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN, 
0,0,640,480,0,0,GetModuleHandle(NULL),0); 
if(!hwnd) return false;
ShowWindow(hwnd,SW_HIDE);

hdc = GetDC(hwnd);
pixelFormat = ChoosePixelFormat(hdc,&pfd);
SetPixelFormat(hdc,pixelFormat,&pfd);
wglMakeCurrent(hdc,wglCreateContext(hdc));
return wglGetCurrentContext() != NULL;
}</code>
