What to expect from GPU PhysX in Batman: Arkham City ?

without comments

Batman: Arkham City tests the patience of PC gamers with several release delays, but will try to wheedle them with DX 11 Graphics and PhysX Technology.

Update: GPU PhysX in Batman: Arkham City - review and comparison video.

Recent comparison trailer gave us a glimpse of extra physics effects, and now we want to provide you with some additional details on what to expect from GPU PhysX content. In addition, new comparison PhysX video was released as well.

As usually, it will be possible to adjust level of in-game physics via “Hardware Accelerated PhysX” option in game’s launcher. There will be three settings:

PhysX Off: all GPU accelerated effects are disabled, only standart CPU physics (like ragdolls) is used.

PhysX Normal: enables additional particles effects (debris, volumetric smoke and steam, etc) and destructible environments.

PhysX High: includes all effects enabled withing “Normal” settings as well as realtime cloth and clothing simulation.

PhysX Research: adding physics to animated characters with Oriented Particles

with 3 comments

Another interesting research paper was published by Dr. Matthias Müller-Fischer, PhysX SDK Research Lead in NVIDIA.

Update: Oriented Particles solver through CUDA

It is called Adding Physics to Animated Characters with Oriented Particles and it further expands oriented particles approach with techniques for simulation of clothing on animated characters.

Abstract:

We present a method to enhance the realism of animated characters by adding physically based secondary motion to deformable parts such as cloth, skin or hair. To this end, we extend the oriented particles approach to incorporate animation information. In addition, we introduce techniques to increase the stability of the original method in order to make it suitable for the fast and sudden motions that typically occur in computer games. We also propose a method for the semi-automatic creation of particle representations from arbitrary visual meshes. This way, our technique allows us to simulate complex geometry such as hair, thick cloth with ornaments and multi-layered clothing, all interacting with each other and the animated character.

Siggraph 2011: The Latest Advances in NVIDIA PhysX and APEX Technology

with 2 comments

Autodesk has published a recorded video of a presentation – “The Latest Advances in NVIDIA PhysX / APEX Technology” – that was performed by Daniel Horowitz, engineering manager for PhysX dev. tools in NVIDIA,  at Siggraph 2011.

Update: MassFX: what is coming in future versions of 3ds Max

This presentation is covering such topics as design principles of PhysX and MassFX plug-ins, relationship between those tools, and is also giving an overview on APEX Clothing authoring process and upcoming features.

Some interesting facts:

  • APEX Destruction functionality will be added to PhysX plug-ins in the future. It was also mentioned, that it will be possible to use to use 3d party tools for fracturing (not only default solution in PhysXLab) and also tweak graphical and physical meshes separately.
  • Next release – PhysX plug-in 2.7 will support PhysX SDK 2.8.4, PhysX SDK 3.1 and APEX 1.1
  • APEX Softbodies module was mentioned.
  • Contact Layers feature (basically, collision filtering) will be added in 2.7 plug-in for Maya, and 2.x plug-in for 3ds Max.
  • Patner integration program. For example, PhysX based rigid bodies from Particle Flow plug-ins will be able to interact with MassFX rigid bodies.
  • mCloth module will be based on ClothFX plug-in from Size8Software, but it will fully interact with MassFX rigid bodies, ragdolls, atachments and so on (nice solution to keep PhysX cloth and APEX focused on clothing simulation for games only).

It was promised that new 2.7 PhysX plug-ins will arrive shortly, in a few weeks, so keep an eye on our website for a full review.

APEX Clothing tutorial: from Maya to UDK

without comments

User monkeYB07 has posted a video tutorial, that covers APEX Clothing authoring process in Maya and further importing of completed clothing asset into Unreal Development Kit.

Update: New complete set of official APEX Clothing tutorials, including assets import and usage in UE3/UDK.

Basic result, working dynamic cloth, can be achieved in less than 10 minutes, but proper tweaking will certanly require more time.

For additional details on APEX Clothing authoring workflow you may refer to NVIDIA tutorials and APEX C page at Unreal Developer Network.
