3DU and GEO equivalents for 3D RichMedia ? #284

Open datalogics-pgallot opened 1 year ago

datalogics-pgallot commented 1 year ago

Table 309 — "Additional entries specific to a 3D annotation" has 3DU and GEO entries: A 3D units dictionary that specifies the units definitions for the 3D data associated with this annotation. See "Table 325 — Entries in a 3D units dictionary". and For Geospatial3D requirement type, a geospatial information section may be present as an attribute within a 3D Annotation. There are further conditions placed on the GPTS and LPTS arrays within the geo-reference coordinate tables to include 3D point values. See 12.10.2, "Geospatial measure dictionary". respectively.

These would seem to be equally applicable to 3D RichMedia, However I am unable to find equivalent entries in table 342 of clause 13.7.2.3.3 RichMediaConfiguration dictionary or in any part of clause 13.7.

@lrosenthol - ?

For 3DU, I did some experiment within Acrobat and it seems it's able to read/write a 3DU entry to the RichMedia annotation dictionary. Not sure whether this is the intended choice though.

Discussed in Prague -original intention was to mirror 3D annots so likely this is an oversight. @lrosenthol to do some research.
