[x3d-public] HAnim Winter and Spring: some progress

Tue Sep 19 03:40:18 PDT 2023

Holger and Andreas, thanks 1M for multiple important steps forward.

Joe, I tried this morning but will not be able to keep up with all of the
suggested modifications while traveling.  I hope that you can incorporate as
much of them as you can in your author drafts.  Next week let's again plan
on model archive resynchronization - with addition of corresponding tool
diagnostics when possible.

Have fun with advanced X3D Humanoid Animation!  8)

all the best, Don

The problem with these models is, that several skin coordIndices are
referenced up to 12 times in several HAnimJoint nodes. This is too much for
a GPU accelerated humanoid. X_ITE only supports 4 references, as specified
as minimum in glTF standard. This is normally enough and there are a lot of
complex glTF models in the Internet, which will work.

When HAnim was implemented as a CPU, these models also worked, but most of
the models consumed so much processing power that there was no real need to
talk about them working.

For this reason and because it allows X3D4.0 and HAnim 2.0, I built the GPU
version, with the trade-off that not all, and especially too complex models,
are no longer supported.

Best regards,

Holger

Thanks, but, the today published Lief model displays but has several
failures in X_ITE. Choose Look At and scroll to get it in range to view,
then choose Examine to rotate. It operates by cycling through several
different animations over a 100 second interval.

For the default view (X_ITE) several connections were broken in the code
translation. Leif, Lily, Tufani models broken in same or similar ways, skin
bindings and joint rotations. 

The file labelled X3D Model ("Original XML" although the model was submitted
in.x3dv) works as expected in view3dscene. 

The file labelled Classic VRML (derived from Classic input transcoded to xml
then back to Classic) has simple error will not run.

The file labelled VRML97 will not run, having nodes not in VRML97.

The file labelled labelled Canonical XML worked fine in view3dscene when
downloaded and renamed. 

X3DOM selection fails -  no TimeTrigger node? fixed

X_ITE selection very badly broken for unknown reason(s) same as default
view. 

Joe
