Billboard drawing


i want to show some information about an object in a billboard when its got selected.

the billboard should always have the same size and be always visible on screen.

is it ok to show the billboard with nifty?

how do i draw a single spatial in parallel projection mode or should i just recalculate the size of spatial?

  1. jme way : you can attach it to guiNode.
  2. nifty way : you have to convert 3d coordinates to 2d coordinates of screen. Does jme have project() method ? opengl and jogl have.
