Open Graphic Library is an open-source library for displaying 2D/3D shapes.
a software interface to graphics hardware.

3. implementation
Mesa3D

GLUT
Linux, ported to Win32

4. Using GLUT under Win32 Obtain GLUT from web
Some IDEs ( like Dev-Cpp ) comes with bundled OpenGL/Glut
#include <gl/gl.h>

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)

6. 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)
