Zeigt mal lustige kleine Codes die grafische Effekte,
Physikkramm oder sonst irgendwas lustiges machen.

Hier ein kleiner Code von mir:

Er simuliert die Bewegung eines Doppelpendels, deren Bewegungsgleichung ich vorher in "Theoretische Physik = Mechanik" hergeleitet habe.

Stichwort: Differentialgleichungen, Lagrangefunktion

Im Programm einfach mal ein bisschen mit den Startbedingungen spielen

@STARGATE: witzig, vor allem, wenn man etwas übertreibt und das Pendel
schleudern lässt

@dllfreak2001: Cool, sieht aus wie die Bewegung der Erde in der zeitlupe.
Kontinente entstehen und zerfallen wieder. Genial

@dllfreak2001

wenn es nicht so laggen würde, wäre das durchaus was für ein Spiel als Effekt

dllfreak2001 · Beitrag von **dllfreak2001** » 20.11.2008 20:32

@bobobo
Genau so was meinte ich, perfekt.

@STARGATE

öhm, bei mir lagt nichts... Was meinste denn damit, denn außerhalb von Multiplayerspielen kenne ich keine Lags.
Ist ja auch kein Hyperspeedcode...
