I try to program a 3d-physic simulation, with bouncy collisions, friction, etc. and i have a problems with splitting forces at an inclined plane. i know that(adsbygoogle = window.adsbygoogle || []).push({});

[tex] F_n = F_g * sin(\alpha) [/tex] and

[tex] F_p = F_g * cos(\alpha) [/tex]

[tex] F_n [/tex] ... normal force

[tex] F_p [/tex] ... parallel force

[tex] F_g [/tex] ... gravity force

but i would need this in general, in 3d and working in every dircetion. i don't know the angle of my collosion, but a normal

[tex] \vec{n} [/tex].

[tex] \vec{F_n} = \bar{F_g} * \vec{n} [/tex]

but i can't think of how to do the paralell force.

can anybody help?
