Dummy

Analysis

The incoming light data is simply passed unmodified through the node. Given an optic shape, the dummy acts as an iris: a ray outside of it misses the dummy (see Optic shape).

Ports

input_1

Input port.

output_1

Light ouput. This port delivers a copy of the light data from the port input_1.

Properties

optic shape

The opening of the iris, unbounded (Open) by default, so that all light passes. Any shape with an edge can be set instead. A ray outside of it follows the analyzer’s missed surface strategy: with Ignore it passes unchanged, with Stop it is lost (see Optic shape).
