Mesh

[Eata Kitty Honored Resident]

Simplygon is part of the Unreal engine toolkit and produces accurate LODs automatically. How practical to add it is hard to say as I think you need to do some prep work on your models but anything that improves the auto LODs could save a lot of time and help out mesh amateurs.

Simplygon uses proprietary mesh reduction, which keeps all the geometrical LOD attributes, and also guarantees the visual quality of LOD switching by respecting all critical features. In addition to geometry reduction, material LODs can be automatically created through re-calclation of new UVs and baking of new maps. 

They also have an interesting sounding optimiser. Something for sim wide builds but I don't know how it could be implemented.

A unique revolutionary technology, Proxy LODs are made by generating a proxy mesh (re-meshing) and a new set of textures (proxy maps), that resemble a copy of the base model. In large scenes ProxyLODs can replace large groups of static objects, containing many materials and meshes, thereby significantly reducing the number of draw calls and triangle counts. This technology can also be used for creating low-poly models from game as well as non-game data types such as 3D scan and 3D CAD data.

I agree as would PhysX and many other technologies but right now, I think most of us share the same concerns of fixing what we currently have as a priority.  Search sucks, always has for both in world search and inventory searches.  Teleports are still and always have been iffy. Sim stability is another ongoing issue and the limitations of 40 users to a region is very 2003.

True, many great products out there but it sort of like strapping a jet engine on a skateboard.  I think most would agree that they need to fix what we have first.

They were meant to do that in 2007 with the whole open letter situation...

[Rage Riptide]

One word. Impossible. For many reasons.

[Yurii Velinov]

No, it would be possible for anyone except Linden Labs...

Your quote should tell you this is not going to be added to the SL Viewer, which isopen source.

Simplygon uses proprietary mesh reduction, ...

If the Lab were to purchase the rights, then it still would not appear in the third party viewers.

So is the JPEG2000 uploader?

The mesh uploaders physics shape generation is also proprietary.
