Thanks Thanos.  I can discuss this together Monday or Tuesday if you like,
it is always good to understand a  problem fully before pursuing
corrections.

 

all the best, Don

Hi all and Happy new Year. 

I will look it next week and see what we can do. On the other hand
enumerations is a matter of implementation, however some of them might be
necessary

Hi guys, hope you are well.

 

I'm applying X3D naming conventions to Web Audio API enumerations.
capitalizing constant names, changing hyphens to underscores.

 

Problem report: during this effort have uncovered some apparent omissions in
our specification.

 

We have support for only 5 of 10 sets of enumerations.  The following
enumeration sets are omissions.  This implies that corresponding fields in
nodes are missing too.

Looks like we might have already uncovered some X3D4 omissions.  ouch.

 

Discussion here on mailing list please.  Tracking issue as

*	Mantis 1420: Missing 5 enumeration sets (and likely fields) from Web
Audio interfaces
*	https://www.web3d.org/member-only/mantis/view.php?id=1420

 

Please look over these missing interfaces, and where they belong, and then
let's figure out next steps.

 

p.s. X3D XML Schema and DOCTYPE revised, updated the other already-existing
interfaces with capitalized enumeration names:

 

*

Thanks in advance for another round of close scrutiny on this important
capability for spatialized high-fidelity computational sound in X3D4.

 

all the best, Don
