 float[] coords,
 Color color,
 float pointSize,
 boolean circular)

Create a set of same color and size points for use on a Panel3D.

Parameters:

panel3D - the owner 3D panel

coords - the points as [x1, y1, z1, ..., xn, yn, zn]

color - the color of the points

pointSize - the drawing size of the points

circular - if true, draw round point sprites; if false, square

Method Details
