Splines is an applet that invokes SplinesModel to construct an interactive spline with the specified number of polynomial pieces

public class Splines extends DXMApplet {

public void init() {

super.init() ;
setModel (new SplinesModel(this, 4));

}

class SplinesModel extends Model {

SplinesModel(DXMApplet dxma, int numPolys) {

_numPolys = numPolys;

Get the size of the viewport.

Dimension dim = dxma.getSize();

The base unit of measure for DirectX Media is the meter. Convert the size into meters by multiplying it with the pixelBvr.

_halfWidth = mul(toBvr(dim.width*0.5),pixelBvr);
_halfHeight = mul(toBvr(dim.height*0.5),pixelBvr);

}

private NumberBvr _halfWidth; half width of viewport
private NumberBvr _halfHeight; half height of viewport
