void Carna::presets::CameraShowcaseControl::setMaxDistance ( float maxDistance )

Disallows the camera to move further away than maxDistance from its origin. If the camera currently is further away than maxDistance, it will be moved s.t. it will be maxDistance units away from its origin.

Precondition: minDistance >= 0

void Carna::presets::CameraShowcaseControl::setMinDistance ( float minDistance )

Disallows the camera to move closer than minDistance to its origin. If the camera currently is closer than minDistance, it will be moved s.t. it will be minDistance units away from its origin.

Precondition: minDistance >= 0
