About friction

I've seen your achievement in friction sim.
I believe that the glm::vec3 tangent is already equal to fVel.
You just need to length it, no need to dot about.
Maybe I'm wrong...
I shouldn't pull the change since I haven't tested it.
But I think it will be okay if you use the
fVel = glm::length(tangent) anyway.

Why would they be equal? That may happen only if rVel is perpendicular to the collision normal (i.e. dot(rVel, manifold.Normal) is equal to 0), which is not always the case:

P.S. The logs in the image are from my engine which uses a similar impulse solver anyway.

According to the code.

It should be always equal.
