Thiago mentioned that James removed/changed some code from DynBVH recently that might alter it's performance, I did notice it was about 3x slower than the original DynBVH code base on my workstation, but I didn't see any indication of why in the log files.

Can anyone (James, Solomon) shed some light on these concerns? I also noticed that the build for my 60k triangle mesh is extremely slow.

Hi

I've been using Manta for a while and had an old version checked out of 
SVN, I got a newer version today to play with it and noticed the DynBVH 
was about 5 times slower (general scenes using DynBVH have gone from 
5fps down to below 1fps). I was wondering if this was because it is 
still being worked on, given I can see that you can no longer add 
directly to a DynBVH but have to add to a group and then call rebuild 
passing through to group to generate the DynBVH (which I've noted takes 
in the region of 2 seconds to rebuild) or if something had changed I was 
just not aware of.

Sorry to bother you with small questions like this but I was unsure on 
who to email and your username is the only one on the Manta wiki that 
has contact information.

Kind regarsds,
