SIGGRAPH 2010: Nvidia APEX and Scalability
Nvidia has recently uploaded APEX related presentation called “APEX : Creating scalable immersive game environments” from their SIGGRAPH 2010 sponsored sessions list.
Usual overview of APEX framework and current modules (like Destruction and Clothing), which are already familiar to us from past GDC10 and SIGGRAPH09 sessions, is followed by topic never described in detail previously – Scalability and LOD features inside APEX (starts at 32:55).
In general, it’s devided into two components – scalable parameters for each of the modules (like number of particles or cloth vertices), that can be adjusted during authoring to fit into platform computing capabilities..

..and dynamic LOD system, that manages resources destribution between actors and modules, based on current situation and resources budget (for example, clothing on character closer to the camera will be simulated with higher fidelity).

Now, as we know almost everything about APEX, we just need to wait until it will be released to public (standalone, or integrated into popular engines like UE3).













You managed to watch the APEX video very fast and write this post, considering when the videos became available…

The presentation had a good level of detail, better than previous years.

Not as fast as I planned

Indeed. APEX is now close to release, afaik.

Interesting. LOD is realy good implemented i guess. Destructibles are easier to create but i prefer something procedural, generating realtime. Also i miss some way to create structures like that, static with breakable joints:

So far there is not enough info to show that this isnt possible. Apparently there is a CPU interface so perhaps that could be used to generate new geometry Just In Time.

CPU should have been C++ …

The static objects with breakable joints are still implemented in the Unreal Development Kit, they are actually a bunch of simple Kactor’s with rigid body physics, interconnected with Joint actors. there are quite a few ways people could do this and still can! I have upgraded in my work now and use metal cloth beams interconnected with joints. it’s basically a paint weighted plane mesh with a cloth bone and no rigid vertices exported with the actor-x plugin. the cloth objects yield excellent results with compartment mode on! anyways I am eager to try the apex module : )
