Using GLUT under Win32 Obtain GLUT from web http://192.48.159.181/resources/libraries/glut/glut_downloads.html Some IDEs ( like Dev-Cpp ) comes with bundled OpenGL/Glut #include <gl/gl.h> #include <gl/glut.h> // handles windows

Create a Window And add event handler Enable OpenGL Disable OpenGL Exit Calculate the moment And motion, Finished? Yes No Calculate the screen points Clear the device Draw the shape(s)

Prototype void DisableOpenGL (HWND hWnd, HDC hDC, HGLRC hRC); LRESULT CALLBACK WndProc (HWND hWnd, UINT message,WPARAM wParam, LPARAM lParam); void EnableOpenGL (HWND hWnd, HDC *hDC, HGLRC *hRC); void DisableOpenGL (HWND hWnd, HDC hDC, HGLRC hRC); void Simulate(); int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int iCmdShow)
