GPU PhysX effects will appear in Rise of the Triad

without comments

As revealed in a recent developer video blog, Rise of the Triad title, remake of the original 1995’s Rise of the Triad game, will offer support for GPU accelerated PhysX effects.

Unreal Engine 3 powered remake is developed by a company called Interceptor Entertainment and is slated for release on PC in 2013 via Steam.

As showcased in the production diary (at 3:00), PhysX effects will at least include physical particles (impact chunks and debris, standart stuff) and destructible environments (probably, APEX based).

Be sure to check game’s website -  RiseoftheTriad.net – for more information.

And to keep an eye on other upcoming projects, featuring PhysX support, don’t forget to visit our Upcoming GPU PhysX games page.

Online shooter Warframe to feature GPU PhysX support

with 6 comments

Eager to see what kind of GPU PhysX games can one expect in 2013?

Welcome Warframe – online free-to-play third person shooter/slasher, being developed by Digital Extremes, a company that has brought as games such as The Darkness 2 and Dark Sector.

Update: official PhysX trailer available

As wielders of Warframes, ancient combat exoskeletons, players will have to fight their way, with swords and guns, through procedurally generated levels across the Solar System.

Intense cooperative PvE (up to 4 players) gameplay of Warframe is complemented by several MMO-style features, such as crafting system, upgradable equipment and weapons, boss raids, etc.

Warframe is based on the last generation of Digital Extemes’ in-house engine – Evolution Engine – which features not only very nice, DX 11 enhanced visuals, but also PhysX SDK 3.2 and APEX 1.2 integrations.

Hawken PhysX trailer showcases Turbulence and Particle effects

with 6 comments

NVIDIA has released an official trailer, that demonstrates how hardware accelerated PhysX particle effects can enhance the visual look of Hawken, free-to-play MMO mech shooter.

Update: full GPU PhysX support will be enabled in March 5 patch

Hawken incorporates two types of physical effects – APEX Turbulence based particle simulation, and also more common impact debris and weapon effects.

While basic particles were available since the release of the game in December (you can check out our preview for more detailed information), Turbulence effects will be fully enabled in Hawken after a short period of time.

However, one can get an idea of Turbulence even today, by setting

"PhysXLevel = 2"

in game’s .ini file

\Users\Documents\My Games\Hawken\HawkenGame\Config\HawkenEngine.ini

In addition, be sure to check out the “Hawken: Advanced PhysX Effects Coming Soon To Free-To-Play First Person Shooter” article at GeForce.com for more detailed description of current and upcoming GPU PhysX effects in Hawken.

PhysX effects will be re-enabled in PlanetSide 2 with upcoming patch

with 7 comments

During the closed beta, SOE’s PlanetSide 2 has shown us some impressive GPU PhysX tech, such as APEX Turbulence based particles, running on a newest PhysX 3 engine.

However, the hardware PhysX effects have not made it into final release of the game, happened several months ago, as it was decided to enhance some aspects of their implementation.

Now, the wait is nearly over. According to Tramell Ray Isaac, Sr. Art Director of PlanetSide 2 in SOE, GPU PhysX support will be re-enabled in the game with next big update, coming January 30, 2013.

Update: GPU PhysX effects were postponed once again. Mr. Tramell has refused to provide another release date.

Update #2: There is a way to force the PhysX effects to appear in a current state, but is it worth it?

Update #3: GPU PhysX is now officially enabled in PlanetSide 2

PhysX SDK was updated to version 3.2.3

with 3 comments

NVIDIA has released yet another set of bug-fixes for PhysX SDK 3.x

Update: PhysX SDK 3.2.4 is available

nvidia-physx

PhysX SDK 3.2.3 – Release Notes

  • General
    • Quaternions passed through the API are now considered valid if their magnitude is between 0.99 and 1.01.
    • Fixed crash when running out of memory on creation of a triangle mesh.
    • For applications using floating point exceptions, the SDK will now mask or avoid exceptions arising from invalid floating point operations (inexact and underflow exceptions may still be generated).
    • Fixed a bug with recursive use of the PxScene read/write lock.
    • Fixed a shutdown bug with very short lived threads on Linux platforms.
    • PhysX version number in error messages now printed in hex for easier reading.
  • Broad Phase
    • Fixed a broad phase crash bug that occurred when deleting shapes with bounds very far from the origin.

PhysX Research: Fast Simulation of Inextensible Hair and Fur

without comments

New “Fast Simulation of Inextensible Hair and Fur” paper from Dr. Matthias Müller-Fischer and PhysX Research team is a further extension of the work on realtime fur and hair simulation, previously demonstrated at GDC 2012.

Update: Introducing NVIDIA HairWorks – fur and hair simulation solution, based on the research

In this short paper we focus on the fast simulation of hair and fur on animated characters. While it is common in films to simulate single hair strands on virtual humans and on furry animals, those features are either not present on characters in computer games or modeled with simplified textured meshes. The main difficulty of simulating hair in real time applications is the sheer number of hair strands and the fact that each hair is inextensible. Keeping thousands of deformable objects from being stretched is computationally expensive.

In this paper, we present a robust method for simulating hair and fur that guarantees inextensiblity with a single iteration per frame. For an iteration count this low, existing methods either become unstable or introduce a substantial amount of stretching. Our method is geometric in nature and able to simulate thousands of inextensible hair strands in real time.

Like with any other research projects, there is a high probability that this particular technology will be utilized in future releases of PhysX SDK or APEX.

Catzilla: a new cross-API benchmark

without comments

A Beta version of the Catzilla benchmark, developed by Plastic Demo in collaboration with Polish post production company, Platige, is now available for download.

Catzilla is a cross-API (OpenGL 4.0 and DirectX 9/11) benchmark designed the Windows platform, and is also featuring a parallel graphics engine that can take advantage of multi-core CPUs.

Benchmark consists of the main demoscene-style dubstep-heavy giant cat fight scene, which stresses both CPU and GPU, and a set of smaller benchmarks – CPU rigid body physics, GPU smoke simulation, fur rendering, etc.

As interesting note, Catzilla uses PhysX SDK 3.2 as physics engine, however, it is running purely on CPU (as confirmed by one of the developers).

Hawken Open Beta: update on GPU PhysX support

without comments

Online first-person mech shooter Hawken, that may be already familiar to our readers, has reached the Open Beta state this week (whilst release date has been delayed).

Update: Hawken – official PhysX trailer

Update #2: full GPU PhysX support will be enabled in March 5 update

Update #3: GPU PhysX in Hawken – review and benchmarks

What kind of PhysX content current Beta has to offer ? Let’s find out.

Hawken still contains only physical particle PhysX effects, however, they have recieved a noticable overhaul over a recent month. APEX Turbulence based simulations were postponed as it was decided to give them a few rounds of additional polishing. Finally, APEX Destruction module and destructible environments will be added to the game in early 2013.

Current set of PhysX Particles includes following effects:

  • Particles from explosions and impact debris (pieces of concrete, strips of metal, etc).
  • Small parts and chunks flying off on weapon impacts on mechs.
  • Additional debris generated as mech walks, dashes or lands.
  • Forcefields (from explosions and moving mechs) to push around any ambient PhysX particles.

In overall, particle effects are done well, they are pretty intense (battlefield will be covered with chunks and debris in just a few seconds after first machine gun bursts) and are adding a certain amount of juice to the visual look of the game. We can name only one flaw – particle effects lack variety, a little.

APEX SDK was updated to version 1.2.2

with 2 comments

APEX SDK 1.2.2 update is now available for download.

Update: APEX SDK 1.2.3 released

New release features PhysX SDK 3.2.2 support, includes a bunch of bug-fixes and several new interesting features, like the ability to calculate static stress for destructible objects.

Updated authoring tools will follow.

APEX SDK 1.2.2 – Release Notes

  • APEX Framework 1.2.2
    • APEX requires the use of the PhysX 3.x scene multiple-reader-single-writer lock to access both APEX and PhysX scene objects when using the PxSceneFlag::eREQUIRE_RW_LOCK flag. This allows the application using APEX to access PhysX objects from multiple threads.
  • APEX Destruction 1.2.2
    • Option to include use of stress solver in destructibles. The stress solver attempts to detect and break off chunks deemed to be overly-strained.
    • Introduced a new parameter struct “StrutureSettings” in the destructible actor. Parameters that make up “StructureSettings” affect all actors’ settings structure-wide.
    • New parameters “useStressSolver”, “stressSolverTimeDelay” and “stressSolverMassThreshold” introduced for the stress solver.
    • Option to remove all T-junctions from a fractured mesh. This allows post-processing such as deformation to be applied (for example in a DCC tool).
    • Ability to control the interior materials used when fracturing selected chunks.
    • Ability to add noise to the perimeter faces of cutout chunks.
  • APEX Clothing 1.2.2
    • New ClothingMeshSkinningMap API to get mesh skinning information, so it can be done in the application.
    • New API to add collision objects to a clothing actor. This can be used to implement collision with world objects.
