    OpenGL Question?

    What i am doing is making a 3D Checkers game that when its a different players turn the board spins around, I know how to spin the board with glRotatef but how would i make it a different function if the original drawing of the board is in a different function. Any ideas?

    Thanks
    Chris

    are you saying you have two functions and you want to do such

    ??? function1(???)
    {
    // draw the chessboard
    }

    //elsewhere in the code
    ??? function2(???)
    {
    // rotate the chessboard here
    }

    is this what your trying to do?

    Well, you could put a glRotatef in the drawing function, and rotate it THETA degrees, then make THETA a global variable and change it (say from 0 to 180) in the other function.

    Or you might want to take a look at the gluLookAt() function, and then you could just change the position of the camera and swing it around the board, showing you the board from another view.
