It takes multiple inputs from sensors, video and sound links and consolidates them, relays them to laptopsand allows the team to process them in 'mission control'.

The simplest kinds of pixel shaders output one screen pixel as a color value; more complex shaders with multiple inputs/outputs are also possible.

Processes receiving multiple inputs need to define how to respond.

Multiple inputs and multiple outputs can be represented using multiple graphs or multiple mappings in a single graph, respectively.

They contain multiple inputs and outputs, and allow any combination of input channels to be routed to any combination of output channels.
