Data in IRIS Explorer

Data passed between modules is characterised by its type

Data is passed through module input and output ports

Each port accepts or outputs only one type

Users can add new types

The data types are:

Parameter
A scalar value. Used to control behaviour of module
Lattice
A generalised, multi-dimensional array having data and coordinates. Used to store point - based values
Pyramid
A hierarchy of lattices, with information on how they are connected. Used to store element (edge, face, volume...) - based values
Geometry
An Open Inventor scene graph (collection of geometric primitives)
Pick
A set of information about part of a scene displayed by a module
