Detailed Description

Selectively copies its input to its output.

This engine selectively copies its input to its output. The type of the input field can be any subclass of SoMField. The type is specified when an instance of the class is created. For example, SoGate( SoMFFloat::getClassTypeId() ) creates an engine that copies floating-point values.

The enable input controls continuous flow-through of values. While enable is TRUE, the input will be copied to the output. Alternatively, by touching the trigger input, you can copy a single value from the input to the output.

Note that by default input does not contain any values. Note also that unlike most other engine fields, input and output are pointers.

FILE FORMAT/DEFAULT
