A 3d morpho-kinematic study of ngc 3132

We present a new modeling tool for planetary nebulae (PNe), based on 3D photoionization calculations. From models for two theoretical PNe, we show that the intensity enhancement in the equatorial zone, observed in several of these objects, is not necessarily due to a density gradient as usually interpreted. We study the morpho- kinematic properties of the PN NGC 3132 and show that a bipolar Diabolo shape successfully reproduces the main trends in the observed high resolution images.
