This is probably not the best way, but you can use Primitives.getPlane() to create an Object3D plane and use setTransparency() on it. Then apply a texture that would have a drawing of your 2D shape on it.

seems as java.awt.geom package is the engine you are looking for ;)

i know almost nothing about open gl but i will most likely go after the Mr.Marbles' approach. java.awt.geom package can help to generate textures on the fly
Code: [Select]

Generating textures on the fly to do this is suitable if it's all part of a 3d application. But if this is a 2d application, i don't recommend to use jPCT for this at all...it's a 3d engine, not a function plotter.

Ok, thanks. Anyway to draw just a point on a pixel?, I can manually draw the lines.
