Modules
	Object Accessors
	Object accessors provide access to computation providers, the scene objects from which input values are requested.
	Value Specifiers
	A value specifier is an element of an input registration that identifies the value that is requested from a given computation provider.
	Input Options
	An input option is an element of an input registration that applies to a value specifier, modifying its behavior.
	Aliases
	Aliases are compact representations of compound input registrations, combining one or more object accessors with a value specifier into a single input registration.

Detailed Description

An input registration is a specification of how an input value will be provided to a computation callback at evaluation time.

An input registration is a sequence of:

• zero or more object accessors, which provide access to one or more scene objects that act as computation providers, and which must be followed by:
• exactly one value specifier, which request a value from the computation provider(s), and which may be followed by:
• zero or more input options, which modify the behavior of the resulting input registration.

For convenience, certain object accessor/value specifier/input option sequences may be replaced by an alias, which compactly represents a compound input registration.
