How to adjust the focal length of the perspective Camera?

Hi,

I would like to know how to increase or decrease the field of view of the camera or the focal length after placing the Camera at a fixed location.

I would like my camera to be fixed at location (0.2, 0.8, 0.56) so I set it using perspectiveCamera->SetPosition(Vec3f(0.2, 0.83, 0.56));. How can I adjust the field of view of the camera at this location? Do you currently have support for this?

Thanks,

Micael

PerspectiveCamera::SetFovY Sets the horizontal field of view in degrees.

And for depth of field there is PerspectiveCamera::SetFocalDistance(float focalDistance) and PerspectiveCamera::SetApertureRadius(float apertureRadius).
