Vectrosity 1.4 drawpoint3D

I’m use Vectrosity to draw point cloud that i can explore in first person.
I make e test javascript (drawpoint3D command) that I add on main camera of first person controller.
Vectrosity draw point correctly, but every point is a little plane and when I go behind they disappear.
How can I solve to see any point to any position?

Use a 2-sided shader, such as the particle shaders, or call DrawPoint3D whenever the camera moves, so the points are always facing the camera.
