Spring box constraint for MotionBuilder

Значение параметров

Stiff — жесткость пружины (чем больше значение, тем более жесткая) Жесткость заключается в реакции и силе самой пружины, с которой она тянет точку в исходное положение.

Damp — размер угасания колебаний пружины (чем больше, тем меньше колебаний совершает пружина) Суть этого параметра под большим вопросом, на практике он дает несколько неверный результат, поэтому иногда угасанием колебаний можно считать постоянное значение 0.10 например

Length — длина пружины (следует устанавливать в 0) При значении ноль исходным положением является поступающее положение точки, иначе пружина будет пытаться занят позиции на указанном расстоянии от поступающего

Mass — масса. Чем больше масса тем сложнее пружине сдвинуть точку с места или наоборот вернуть её в исходное положение.

Friction — сила сопротивления, позволяющая «заглушить» динамику пружины и вернуть её в исходное положение. Чем больше значение тем меньше «эффект пружины»

Pos — позиция на входе
Result — позиция на выходе

    Уау, клевая штука! Я когда-ты пытался сообразить такое на основе Relation, но как-то зашел в тупик и бросил это дело.
    Спасибо за плагин.

    А можно посмотреть на реализацию этого в коде? (C++, как я понимаю?)
    ?ли это совсем не скромная просьба? :)

    Посмотреть можно, выложил исходный код плагина под 2008ю студию. Сама пружина представляет собой реализацию алгоритма Эйлера и конечно для большей устойчивости хорошо было бы дописать Рунга-Кутта, но на это нет пока что времени…

    Прошу прощения, но как его установить и опробовать?
    у меня MoБи 2009 х32 стоит в C:\mb2009\
    скопировал длл в C:\mb2009\bin\plugins,
    запустил — не могу его нигде найти.
    потом скопировал длл в C:\mb2009\bin\win32\plugins, все равно его не нахожу :(

    плагин находится в группе Physics ограничителя Relation. По поводу использования, я записывал небольшой видео тутор, там видно где искать — http://www.youtube.com/watch?v=647yDJijK2k
    А копировать длл следует в bin/win32/plugins

    Unfortunately in Britain parking your bike and not locking it to something is very much fowned upon, and not recommend. Unfortunately most bicycles sold in Britain lack stands and wheel locks which in park enables the ability for people to park without locking to something. I wonder what else would make people in Britain more likely to park their bikes without locking it to a frame?
