I was checking the source code of SuperEllipsoidMeshBuilder example here: http://haptic-data.com/toxiclibsjs/examples/SuperEllipsoidMeshBuilder_pjs-webgl.html

And i was playing with the source code as below:

if(!isWireFrame)
  {
   
      for(i=0;i<numFaces;i++)
      {
          Face f = faces[i];
          toxi.Vec3D a = f.a;
          toxi.Vec3D b = f.b;
          toxi.Vec3D c = f.c;
       
          //normal(a.normal.x,a.normal.y,a.normal.z);
          vertex(a.x,a.y,a.z);
          //normal(b.normal.x,b.normal.y,b.normal.z);
          vertex(b.x,b.y,b.z);
          //normal(c.normal.x,c.normal.y,c.normal.z);
          vertex(c.x,c.y,c.z);
      }
    }
    else
    {
       
        for(i=0;i<numFaces;i++)
        {
            toxi.Face f = faces[i];
            toxi.Vec3D n = f.normal;
            toxi.Vec3D a = f.a;
            toxi.Vec3D b = f.b;
            toxi.Vec3D c = f.c;
            //normal(n.x,n.y,n.z);
            vertex(a.x,a.y,a.z);
            vertex(b.x,b.y,b.z);
            vertex(c.x,c.y,c.z);
        }
    }
    endShape();
   
    /*if(len>0){
        int strokeCol = 0;

        int j;
        if (!isWireFrame) {
                toxi.Vertex[] vertices = mesh.getVertices();
                int numVertices = vertices.length;
            for (j=0;j<numVertices;j++) {
                    toxi.Vertex v = vertices[j];
           
                    toxi.Vec3D w = v.add(v.normal.scale(normalLength));
                    toxi.Vec3D n = v.normal.scale(127);
                    stroke(n.x + 128, n.y + 128, n.z + 128);
            //stroke(0, 0, 255);
                    line(v.x, v.y, v.z, w.x, w.y, w.z);
                }
            } else {
                float third = 1.0 / 3;
               
                for (j=0;j<numFaces;j++) {
                    toxi.Face f = faces[j];
                    toxi.Vec3D c = f.a.add(f.b).addSelf(f.c).scaleSelf(third);
                    toxi.Vec3D d = c.add(f.normal.scale(normalLength));
                    toxi.Vec3D n = f.normal.scale(127);
                    stroke(n.x + 128, n.y + 128, n.z + 128);
                    line(c.x, c.y, c.z, d.x, d.y, d.z);
                }
            }
        }*/

As you can see i commented the if(len>0) part. By pressing w, it is possible to see wired mesh and a filled version. Although the two if-else part is same, why is the pressing 'w' resulting in a filled version of the mesh?

Also i wonder, whether i can change the mesh's z value. I mean, i change the line as toxi.SurfaceFunction functor=new toxi.SuperEllipsoid(1, 1); and created square partitions. I want the z value of these grid partitons defined as custom when they are filled. So i want to see some parts higher, some not. How can i do that?
