created a function for an ellipse

[raydeleu]

In my experiments how to add new functionality to CascadeStudio I tried to create a function to create an Ellipse. It is a copy of the function Circle but with an added parameter (for the minor radius). The function calls GC_MakeEllipse instead of GC_MakeCircle and seems to work just fine.

function Ellipse(radius1, radius2, wire) {
  let curEllipse = CacheOp(arguments, () => {
    let ellipse = new oc.GC_MakeEllipse(new oc.gp_Ax2(new oc.gp_Pnt(0, 0, 0),
      new oc.gp_Dir(0, 0, 1)), radius1, radius2).Value();
    let edge = new oc.BRepBuilderAPI_MakeEdge(ellipse).Edge();
    let ellipseWire = new oc.BRepBuilderAPI_MakeWire(edge).Wire();
    if (wire) { return ellipseWire; }
    return new oc.BRepBuilderAPI_MakeFace(ellipseWire).Face();
  });
  sceneShapes.push(curEllipse);
  return curEllipse;
}
