ATLAS REMESHED

Atlas Remeshed is created as a single smooth surface obtained by a computer graphic process starting from the original tracks of the 3D CERN file kindly provided by the CERN-ATLAS Experiment.
CERN scientists generated a 3D model of a Higgs candidate event, resulting in a signature composed of 2 muons and 2 electrons. It is the same event that has been used for the animation of a ATLAS proton collision event to show a Higgs candidate event in 2011: Proton Collision Event with 2 Electrons & 2 Muons (http://www.atlas.ch/multimedia/#2-electron-2-muon-event).

What is ATLAS ? (Text from Atlas experiment website: http://atlas.ch)
ATLAS is a particle physics experiment at the Large Hadron Collider at CERN. The ATLAS detector is searching for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, microscopic black holes, and evidence for dark matter candidates in the Universe.
What is the Large Hadron Collider (LHC) ? (Text from Atlas experiment website: http://atlas.ch)
The protons are accelerated in opposite directions in the Large Hadron Collider, an underground accelerator ring 27 kilometres in circumference at the CERN Laboratory in Geneva, Switzerland. Crashing together in the center of ATLAS, the particles will produce tiny fireballs of primordial energy.
LHC recreates the conditions at the birth of the Universe, 30 million times a second. Relics of the early Universe not seen since the Universe cooled after the Big Bang 14 billion years ago will spring fleetingly to life again. The LHC is in effect a Big Bang Machine.

The artwork curves are the same tracks of the 3D CERN file. Blue segments are the electrons and muons released during the collision: muons are represented as two long tracks, while electrons as two short blue tracks.
The metallic smooth volume is obtained by a computer graphic process called “Remeshing”. The original 3D file is composed by a lot of 3D objects (the tracks). Remeshing algoritm is a way to create a new single object by combining several existing objects. The used algoritm analizes the proximity between different elements (red tracks) and builds a unified skin as organic surface representing the proximity relationship. The purpose of this process is to change the event visualization pointing out the presence of muons and electrons, important elements for the experiment. The result of this work is a virtual model that can become the real sculpture.

The aluminium sculpture is made of the succession from two separate processes. The first process is the laser sintering: the virtual model is cut in layers of 0.15 mm and loaded in the laser sintering machine. A high power laser solidifies the nylon powder, layer by layer, making a physical model with precision and potentially unlimited complexity. The second process is the lost-wax casting: this technology is basically the same as the one used three thousand years ago. The forming system, cooking and evaporation remaied the same during the last thousand years. The model is used as wax, and it is lost during the casting.
