Particle System Prototype

Palle Dahlstedt · Gothenburg University Publications Electronic Archive (Gothenburg University) · 2013

This is a preparatory work for a larger installation planned to be performed during the Tllberg Workshop @ CERN in September 2014.The purpose of this workshop is to discuss, on a deeper level, the interactions between science, technology and art, and I was asked to contribute.The workshop is a collaboration between Tllberg Foundation and CERN.It will take place at the CERN facilities in Geneva, and this installation was originally planned to be performed in one of the sensor halls of the Large Hadron Collider (LHC).This is however not finally decided.I am part of the organizing group at Tllberg Foundation, and I have been invited to contribute artistically to the event.The work presented here was performed during a workshop at the quite well-known globalization forum Tllberg Forum, preparing for the larger workshop at CERN.The participants were physicists, environmental scientists, artists, art historians, politicians and business decision-makers.

Particle System Dynamics

Andrew Witkin, Andrew Witkin · 1992

Particles are objects that have mass, position, and velocity, and respond to forces, but that have no spatial extent. Because they are simple, particles are by far the easiest objects to simulate. Despite their simplicity, particles can be made to exhibit a wide range of interesting behavior. For example, a wide variety of nonrigid structures can be built by connecting particles with simple damped springs.

Particle detection system.

Howcroft, Bryan John, Lisi, Christopher Robert · Digital WPI · 2002

The goal of this project is to determine the feasibility of a system which detects and locates high speed particles entering an air intake system, specifically on jet engines. A prototype of the system was created. Testing was completed both in the lab and in the field with high speed projectiles. The project concludes that in order to determine the position of particles in two dimensions, data latching independent of the microcontroller is required.

Niagara particle system

Diaz de Garayo Serrano, Unai · QRU Quaderns de Recerca en Urbanisme · 2023

Los sistemas de partículas son un elemento muy importante de los videojuegos que aportan realismo e inmersión al jugador, estas, combinadas con efectos de postproducción, aportan detalles y completan la escena visualmente para que no parezca que falta algo o que la escena está vacía , no solo son importantes a nivel visual, también hay mecánicas que pueden basarse en este tipo de simulaciones. El problema que presentan este tipo de simulaciones es que si se pretende conseguir resultados muy realistas, estas requieren de un gran cálculo de físicas y de renderizado que afectan al rendimiento general del juego, por lo tanto, es importante encontrar un sistema que consiga un punto medio que combine un buen resultado que sea creíble para el jugador, con una buena optimización que no afecte drásticamente al rendimiento del juego. Para desarrollar este sistema se van a crear dos sistemas de partículas diferentes, una que simula de manera físicamente realista una simulación de humo con un renderizado de densidad realista, usando técnicas de Ray Tracing y de guardado en caché de la simulación para mayor optimización. Por otra parte, el otro sistema estará más enfocado a la optimización, pensado para que afecte lo menos posible al rendimiento, pero también pensado para conseguir resultados que sean completamente creíbles para el jugador, este último sistema estará pensado para ser usado como los sistemas de partículas de Unity o Unreal, que dan más flexibilidad para crear todo tipo de sistemas. El objetivo será comparar rendimientos y resultados de ambos sistemas para determinar cuál es más óptimo para ser usado en un contexto de real time y cuál es más apropiado para ser usado en un contexto donde los tiempos de cálculos no son tan relevantes como puede ser la industria cinematográfica.

Particle Velocity Measuring System

Arndt, G. Dickey, Carl, James R. · NASA Technical Reports Server (NASA)

Method and apparatus are provided for determining the velocity of individual food particles within a liquid/solid food mixture that is cooked by an aseptic cooking method whereby the food mixture is heated as it flows through a flowline. At least one upstream and at least one downstream microwave transducer are provided to determine the minimum possible travel time of the fastest food particle through the flowline. In one embodiment, the upstream detector is not required. In another embodiment, a plurality of small dipole antenna markers are secured to a plurality of food particles to provide a plurality of signals as the markers pass the upstream and downstream transducers. The dipole antenna markers may also include a non-linear element to reradiate a harmonic frequency of a transmitter frequency. Upstream and downstream transducers include dipole antennas that are matched to the impedance of the food slurry and a signal transmission cable by various impedance matching means including unbalanced feed to the antennas.

Node-based particle system

Luque Bodet, Aitor · QRU Quaderns de Recerca en Urbanisme · 2022

Particle systems attempt to recreate complex natural phenomena through graphical rendering techniques. Nowadays Particle Systems are used in numerous digital applications such as video games, animations, films and all kind of digital art creations. This project aims to develop an open-source engine application to serve as a fast and understandable editor tool for creating complex Particle Systems simulations, working towards a process speed up of the big time investment this task usually takes. The tool will be completely managed by a nodal interface, with all the necessary nodes and components required to create such simulations. The engine uses C++ as the main programming language, OpenGL for 3D graphics rendering and ImGui to build the user interface and the nodal system. That system will be able to create and edit a wide amount of nodes storing parameters and particle systems components along their interactions, intended to be designed for users without any previous technical experience. The structure of the tool is built as a resemblance of already existing engines with node-based procedural generation tools such as Unreal and Houdini.

Microgravity particle reduction system

Tubbs, Tracey, Brandon, Vanessa, Joslin, Michelle et al. · NASA STI Repository (National Aeronautics and Space Administration)

The Controlled Ecological Life Support System (CELSS) project, sponsored by NASA, is assembling the knowledge required to design, construct, and operate a system which will grow and process higher plants in space for the consumption by crew members of a space station on a long term space mission. The problem of processing dry granular organic materials in microgravity is discussed. For the purpose of research and testing, wheat was chosen as the granular material to be ground into flour. Possible systems which were devised to transport wheat grains into the food processor, mill the wheat into flour, and transport the flour to the food preparation system are described. The systems were analyzed and compared and two satisfactory systems were chosen. Prototypes of the two preferred systems are to be fabricated next semester. They will be tested under simulated microgravity conditions and revised for maximum effectiveness.

Particle beam injection system

Daniel L Jassby · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

This invention provides a poloidal divertor for stacking counterstreaming ion beams to provide high intensity colliding beams. To this end, method and apparatus are provided that inject high energy, high velocity, ordered, atomic deuterium and tritium beams into a lower energy, toroidal, thermal equilibrium, neutral, target plasma column that is magnetically confined along an endless magnetic axis in a strong restoring force magnetic field having helical field lines to produce counterstreaming deuteron and triton beams that are received bent, stacked and transported along the endless axis, while a poloidal divertor removes thermal ions and electrons all along the axis to increase the density of the counterstreaming ion beams and the reaction products resulting therefrom. By balancing the stacking and removal, colliding, strong focused particle beams, reaction products and reactions are produced that convert one form of energy into another form of energy.
