It is the wrapper around the Havok functionality in the viewer.  It 
replaces (and incorporates) llconvexdecomposition.

For open source, there is a stub version.

Which is unfortunate... because Open Source viewers all use HACD to
replace the closed source llconvexdecomposition.

I'd suggest that the HAVOC stub is kept separate from the
llconvexdecomposition stub.

Could somebody hit the Jira with this so it can be hopefully properly

Fourthed !
But am 100% Oz will receive a message from the top regarding this! Bah ..
moving on. When fear drives things instead of true openness, opensource
efforts get hurt.

We use Havok libraries as our implementation of llconvexdecomposition.
The interface to llconvexdecomposition has not changed, only the packaging
of it, as we needed to add more havok functionality to the viewer for
pathfinding.

You should be able to tie in HACD to llphysicsextensions and leave the rest
stubbed out with minimal effort. If anyone has difficulty with porting to
the new structure do let us know, and we'll help how we can.

Separating out the two parts would just result in havok libraries that are
shared between convex decomposition and the pathfinding functionality being
linked in twice for the main viewer.

Has the llphysicsextention stub source been pushed to a public repo
yet? Last I heard there was some closed sources bits that needed to be
sorted out still.

If the efforts are so minimal, what about doing it
yourself ?... :-P

I mean, why keeping the llconvexdecomposition stub at all when HACD is
available and used by all OpenSource viewers based off LL's v3 ?...

LL could even drop Havok for mesh convex decomposition: HACD actually
provides much simpler (from the users' point of view) and no less
cost-effective decomps than Havok's, and it lowers the number of
steps necessary to upload a mesh.

And gluing them together causes issues for people using HACD (i.e. all
existing TPVs)... Not that I care much myself since I don't use LL's v3
repository and build system, but others will appreciate your "minimal
efforts" to keep things easy to cope with... ;-)

Regards,

Henri.

This is in fact old news and was mentioned a few times on the ML
already. It might have
been better to bring up a request to keep the functionality split back then.

Under https://bitbucket.org/NickyD/ndphysicsstub you will find a stub for your
pathfinding and mesh upload pleasure. I updated it today to match the
latest PF shiny
and incorporated it into Firestorm with not much fuss.

It's not based on LLs pathing or physics files, so there is no license
from LL attached.

Whoever based their mesh upload on a fork of my original mesh upload
package, might
have to wait until the fork is updated, obviously.

Cheers,
   Nicky
