Setting position of Advanced Camera without interpolation?

How?

Or more precisely, how do I set the camera's transformation matrix such that it essentially doesn't move when I call the the AdvancedCamera::setPosition(Point3F) function?

To put in another way, I want tPos and pos to be the same when the engine evaluates "tPos = getPosition();", so I need to set the camera's transformation matrix before I call setPosition(Point3F).

I've tried modifying AdvancedCamera::setCameraPosition(const Point3F& pos) to:

{
MatrixF transMat = Parent::getTransform();
transMat.setColumn(3, pos);
Parent::setTransform(transMat);

mCameraPos = pos;
setPosition(mCameraPos);
}

... but that seems to have no effect, the camera still interpolates.

Anyone?


EDIT: Note that I would rather not modify AdvancedCamera::setPosition(const Point3F&) such that it doesn't interpolate. I would much rather just add code to AdvancedCamera::setCameraPosition(const Point3F&) that sets the camera matrix then calls setPosition(Point3F), essentially causing the camera to immediately jump to a position.
