    This sample teaches you how to create an OpenGL based Spline Drawing application using the MFC library.

    It shows how to setup 4 Control Points:

    3. Tangent Start Point
    4. Tangent End Point

    • Right click to load the on screen context menu.
    • Left click and drag to move the selected control point around and see its effect on the spline.
    • From the Spline menu, you can select the Type of Spline: Hermite, Cardinal or Bezier.
    • In the same menu you can change the Tension of the control points effect on the spline.
    • You can also select different control points between: Start/End points and Start/End Tangent points.

    Rquirements

    The application requires opengl32.dll for windows which can be obtained from www.opengl.org.

    The original source code for the Spline Drawing Application is GLUT based and I found it posted on www.planet-source-code.com, OpenGL codes link. Please check the sample.
