You see points because your data are sampled by an Irregular3DSet
with manifold dimension = 3. If you used a Linear3DSet, they
would be volume rendered. Except that your data lie on a 2-D
plane, and are organized in a regular 2-D grid.

To see your data displayed as polygons, replace your
Irregular3DSet with a Gridded3DSet with manifold dimension = 2.
The constructor for this is:

  public Gridded3DSet(MathType type, float[][] samples, int lengthX, int 
lengthY)

where samples is the same as in your mytest.java, and lengthX
lengthY = 10.

Good luck,
Bill
