Lerp method suggestion

I was wondering if it would be possible for Lerp methods to return perhaps true or false when they have completed or some form of signal to indicate completion?

You actually control when a lerp "completes" based on the step you pass it. You can consider a lerp to be complete when the step = 1. So just check the step when calling Lerp().

Right okay thats assuming I am using LerpR but I am actually using just Lerp at the moment.

For Lerp its the same, for example:

Code:

for(flt step=0.1f; step<=1.0f; step+=0.1f)

{

      Flt out = Lerp(1, 10, step);

      if(step == 1)

      {

          //if we're here that means job is finished, because step = 1; and out = 10;

      }

}

Hmm okay it won't achieve what I need it to but I have approached this problem in a wrong way maybe.

I need to smoothly transition the camera between two points at a constant rate. GetVel(...) can return the velocity and angular velocity between the two points for me but I can't set the Camera _vel or _ang_vel directly (since they are private) so I tried to interpolate between the dist, pitch, yaw and roll but it is very awkward.

Any suggestions?
