POV-Ray source code for slowing/speeding up time into animations, this is useful i.e. when one wishes to get a bullet time scene where the camera moves at normal speed and other objects slow down in order to watch them in detail, then they accelerate to get back moving at normal speed. An example is included.-POV-Ray source code for slowing/speeding up time into animations, this is useful i.e. when one wishes to get a　bullet time　scene where the camera moves at normal speed and other objects slow down in order to watch them in detail, then they accelerate to get back moving at normal speed.
