I've got another Question.
I'm trying to create a small Effect using a ParticleSystem. It works pretty good when i use a Ring as the Geometry, but i want to use an Ellipse.
Right now my Code looks like this:
particleGeom = ParticleFactory.buildParticles("Portal", 800);
particleGeom.setGeometry(new Ring(new Vector3f(0,0,0),
So how do i create a Geometry for an Ellipse?
