Mattias Lagergren started his studies on the Media Technology Program in 2005 and chose to focus his courses towards the areas of visualization and animation. During the fall of 2009 Mattias did his graduationwork on Fido Film, Swedens leading studio for VFX.

During his graduation work Mattias has developed tools for fluidsimulation in Houdini. The technology he uses is called Smoothed Particle Hydrodynamics, or SPH in short, it is a numerical method to simulate the motion of fluids. It works by dividing the fluid in a set of discreet part, which you refer to as particles. The physical properties of these particles can be obtained by summing all the particles which lie within a certain interaction range from the particle. Mattias work aimed to achieved much improved performance over current commercial software. This is possible through the use of CUDA to unlock the computing powers of the GPU.

On the Media Technology Days Mattias will talk more about SPH and his graduationwork at FIDO.
