I am having a problem displaying a triangle, here is the code: #define WIN32_LEAN_AND_MEAN #include #include #include HDC HHDC; void SetUpPixelFormat(HDC Hdc) { int PixelFormat; static PIXELFORMATDESCRIPTOR PFD; PFD.nSize=sizeof(PIXELFORMATDESCRIPTOR); PFD.cColorBits=16; PFD.iPixelType=PFD_TYPE_RGBA; PFD.cDepthBits=16; PFD.dwFlags=PFD_DRAW_TO_WINDOW|PFD_SUPPORT_OPENGL|PFD_DOUBLEBUFFER; PFD.nVersion=1; PFD.iLayerType=PFD_MAIN_PLANE; PixelFormat=ChoosePixelFormat(Hdc,&PFD); SetPixelFormat(Hdc,PixelFormat,&PFD); } HRESULT CALLBACK WindowProc(HWND Hwnd,UINT Message, WPARAM WParam,LPARAM LParam) { int Height; int Width; HDC Hdc; HGLRC HGlRc; PAINTSTRUCT PaintStruct; switch(Message) { case WM_CREATE: Hdc=GetDC(Hwnd); HHDC=Hdc; SetUpPixelFormat(Hdc); HGlRc=wglCreateContext(Hdc); wglMakeCurrent(Hdc,HGlRc); return 0; break; case WM_CLOSE: wglMakeCurrent(Hdc,NULL); PostQuitMessage(0); return 0; break; case WM_PAINT: Hdc=BeginPaint(Hwnd,&PaintStruct); EndPaint(Hwnd,&PaintStruct); break; case WM_SIZE: Width=LOWORD(LParam); Height=HIWORD(LParam); if(Height==0) {Height=1;} glViewport(0,0,Width,Height); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(0,(float)(Width)/(float)(Height),1.0f,1000.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); return 0; default: break; } return (DefWindowProc(Hwnd,Message,WParam,LParam)); } int WINAPI WinMain(HINSTANCE HInstance,HINSTANCE PrevInstance,LPSTR LpCmdLine,int nShowCmd) { HWND Hwnd; MSG Message; WNDCLASSEX WindowClass; bool Done; WindowClass.cbSize=sizeof(WNDCLASSEX); WindowClass.nostyle=CS_HREDRAW|CS_VREDRAW; WindowClass.lpfnWndProc=WindowProc; WindowClass.cbClsExtra=0; WindowClass.cbWndExtra=0; WindowClass.hInstance=HInstance; WindowClass.hIcon=LoadIcon(NULL,IDI_APPLICATION); WindowClass.hCursor=LoadCursor(NULL,IDC_ARROW); WindowClass.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH); WindowClass.lpszMenuName=NULL; WindowClass.lpszClassName="Window Class"; WindowClass.hIconSm=LoadIcon(NULL,IDI_APPLICATION); if(!RegisterClassEx(&WindowClass)) return 0; Hwnd=CreateWindowEx(NULL,"Window Class","OpenGL Game Engine", WS_VISIBLE|WS_SYSMENU|WS_OVERLAPPEDWINDOW,100,100,700,700,NULL, NULL, HInstance, NULL); if(!Hwnd) return 0; ShowWindow(Hwnd,SW_SHOW); UpdateWindow(Hwnd); Done=false; while(!Done) { PeekMessage(&Message,Hwnd,NULL,NULL,PM_REMOVE); if(Message.message==WM_QUIT) { Done=true; } else { glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glTranslatef(0.0f,0.0f,-5.0f); glColor3f(1.0f,1.0f,1.0f); glBegin(GL_TRIANGLES); glVertex3f(0.0f,0.0f,0.0f); glVertex3f(1.0f,0.0f,0.0f); glVertex3f(1.0f,1.0f,0.0f); glEnd(); SwapBuffers(HHDC); TranslateMessage(&Message); DispatchMessage(&Message); } } return Message.wParam; } PROGAMERS
