Class SoElapsedTime

  • All Implemented Interfaces:

    public class SoElapsedTime
    extends SoEngine
    Basic controllable time source. This engine functions as a stopwatch; it outputs the time that has elapsed since it started running. By default, the timeIn input is connected to the realTime global field. It can, however, be connected to any other time source.

    The ouput from the engine is the time that has elapsed since it started running, or since the reset input was last triggered. You can affect the speed of the output time by setting the speed scale factor. A value greater than 1.0 will speed up the output, and a value less than 1.0 will slow it down.

    If you pause the engine, by setting the pause input to true, it stops updating the timeOut output. When you turn off the pause, it jumps to its current position without losing time. Alternatively, if you want to stop the engine for a while, and then restart it from where it left off, use the on input field.

    File format/default:

    ElapsedTime {

      timeIn <current time>
      speed 1
      on true
      pause false
