[Algorithms] Physic : impulse computation

[Christian B. <br...@if...>]

Hello,

[warning, frenchglish message follows...]

I have a question on impulse computation for the particular case where one
of the colliding objets has an infinite mass. I mean, this object cannot
change its position or orientation.

In the case where 2 "moveable" objects collide, i know how to compute the +F
and -F forces that will prevent inter-penetration, but these forces apply to
both objects, and change the position and orientation of my "fixed, static"
object.

To prevent the fixed object from moving, or rotating, is it "physically
correct" to apply 2*F to the only moveable object and a null force to the
fixed object ?

any help greatly appreciated
Christian
