3D Particle Systems?
Yesterday, I coded my own Particle Engine, but It''s restricted to 2Dimensional only..
How should I do to implement a 3Dimensional Particle engine?
Textured, Solid Squares?

What do you mean by ''for 2D only''?
What is in your opinion a 3D particle system?

That''s not strictly true. Although the particles are rendered using 2D methods, their positions and velocities use 3 dimensions. Which is pretty much the accepted way of doing a particle system in 3D. You could have true 3D particles, but for most cases, you wouldn''t get enough visual/physical improvement to justify the increase in triangle count.
Just as NewDeal sez, I want to have a quad with the particle texture always facing the camera..
So, as he suggested, look up billboards:

Both can be directly applied to particle systems.
