Projects / Simulum


Simulum deals with different simulations of star movements and their visualizations. At first it looks at the projection and accumulation of star brightness. In actually doing this it distributes stars among a three dimensional figure. To get a nice effect it combines the photographic image production with a moving view point. So the outcome is the visual impression of flying through a star field. Secondly it studies different algorithms of particle movements and clustering. The primary approach uses a combination of Newton's gravitational law, energy, and impulse conservation. At all these stages an highly dynamic view of the processes is able to be produced.

    Release Notes: A huge refactoring phase took place. Now the code is much better organized. A simple gravity engine is included, so you can watch gravity at work. It has now a nice GUI. You can browse the simulation with your mouse. The provided unsigned jar includes an applet that can directly be used by HTML pages; this release includes sample HTML pages. You can also webstart the signed jar or start it with "java -jar lib/mulumis.jar".

      Release Notes: Width and height have no influence on the projection. Adjustable parameters added: "stars" (number of stars); "delta" (movement speed); "radius" (viewpoint distance); "sensitivity" (star brightness); "normale" (boolean)(adjust normale to zero point); "linear" (boolean)(linear or circular movement).
