Ri2DWindow

Encapsulates a glut window for 2D drawing.

class Ri2DWindow : public RiWindow

u zoom in o zoom out i move up j move left k move down l move right

Default Constructor

    Ri2DWindow(int sizeX = -1, int sizeY = -1, int posX = -1, int posY = -1);

Set the fraction of the window to translate with each key press

    void SetTranslateFraction(RiReal newFraction);

Set scale base for scaling. 2 means double/half each time.

    void SetScaleBase(RiReal newBase);

Print the help for this window.

    virtual   void  PrintHelp();

Handle keyboard input

    virtual void Keyboard(unsigned char key, int x, int y);

actions to be performed upon reshaping the window size[XY] and pos[XY] will have been updated.

    virtual void Reshape();

really open the window

    virtual void DoOpen();

really notify the system that the window needs to be redrawn

    virtual void DoSetSize();
