Overview Of Graph3d

The graph3d package allows easy-to-implement and visually demanding display of explicitly defined and numerically evaluable functions using two or three floating point arguments.

The package provides a heavy weight UI component, graph3d.GraphView, which provides built-in support for basic model manipulation like zooming and rotating the graph on mouse-drag, and automatic fit on viewport resizes. The GraphView also provides an API, which allows selection of various display properties like pointset-, wireframe and smooth shading modes, lighting parameters etc.

To create a viewport for a function f(x,y) := x * y, the following code would be required:

    ...
    JFrame frame = new JFrame("Graph3d Test");
    graph3d.GraphView view =
       new graph3d.GraphView(
          new graph3d.Function() {
	     public double call(double x,double y)
	     {
	        return x * y;
	     }
	  });
    frame.getContentPane().add(view);
    ...
   
To pass functions to the GraphView, there are two different strategies available,supported and indicated by usage of appropriate interfaces:
