All input devices that Java 3D uses must implement the InputDevice interface and be registered with Java 3D via a call to PhysicalEnvironment.addInputDevice(InputDevice). An input device transfers information to the Java 3D implementation and Java 3D applications by writing transform information to sensors that the device driver has created and manages. The driver can update its sensor information each time the pollAndProcessInput method is called.<P><P><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/InputDevice.html#BLOCKING">BLOCKING</A></B></CODE><BR> Signifies that the driver for a device is a blocking driver and that it should be scheduled for regular reads by Java 3D.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/InputDevice.html#DEMAND_DRIVEN">DEMAND_DRIVEN</A></B></CODE><BR> Signifies that the Java 3D implementation should not schedule regular reads on the sensors of this device;
