managed to figure out a way of getting a semi volume effect in XSI using my own particle grid in ICE and reverse engineer some very interesting math and physics algorithms. here we can see Mitosis, diffuse reaction and a Cassini Oval, real time implementation captured from the viewport, Next , My own custom interpretation of Houdinis 'Alligator Noise' on a 2D and 3D grid at the same time. Next I explore a pyroclastic effect using Exponent Power maths with varying noises added in
