MedicalInterchange profile

--- X3D separator bar ---

cube L.1 General

This annex defines the X3D components that comprise the MedicalInterchange profile. This annex includes not only the nodes that shall be supported but also which fields in the supported nodes may be ignored. 

This profile is targeted towards:

cube L.2 Topics

Table L.1 provides links to the major topics in this annex.

Table L.1 — Topics

cube L.3 Component support

Table L.2 lists the components and their levels that shall be supported in the MedicalInterchange profile. Table L.3 and Table L.4 describe limitations on required support for nodes and fields contained within these components.

Table L.2 — Components and levels

Component Level Reference
Core 1 7.5 Support levels
Time 1 8.5 Support levels
Networking 2 9.5 Support levels
Grouping 3 10.5 Support levels
Rendering 5 11.5 Support levels

Texturing3D 2 33.5 Support levels
Volume rendering 41.5 Support levels

cube L.4 Conformance criteria

Conformance to this profile shall include conformance criteria defined by the specifications for those components and levels listed in Table L.2.

In Tables L.3 and L.4, the first column defines the item for which conformance is being defined. In some cases, general limits are defined but are later overridden in specific cases by more restrictive limits. The second column defines the requirements for an X3D file conforming to the MedicalInterchange profile. If an X3D file contains any items that exceed these limits, it may not be possible for an X3D browser conforming to the MedicalInterchange profile to successfully parse that X3D file. The third column defines the minimum complexity for an X3D scene that an X3D browser conforming to the MedicalInterchange profile shall be able to present to the user. Fields flagged as "not supported" may optionally be supported by browsers which conform to the MedicalInterchange profile. The word "ignore" in the minimum browser support column refers only to the display of the item; in particular, set_ events to ignored inputOutput fields shall still generate corresponding _changed events.

cube L.5 Node set

Table L.3 lists the nodes which shall be supported in the MedicalInterchange profile and specifies any fields in these nodes for which this profile requires less than full support.
