APEX SDK 1.2.3 is now available

with 10 comments

NVIDIA has released an updated version of APEX SDK.

Update: APEX SDK 1.2.4 is available

New version is compatible with latest PhysX SDK 3.2.3, and also includes a bunch of bug-fixes and some minor new features.

APEX SDK 1.2.3 – Release Notes

  • APEX Framework 1.2.3
    • NxResourceProvider is now case-insensitive by default. To get the old case-sensitive behavior, set resourceProviderIsCaseSensitive true in the NxApexSDKDesc.
    • Fixed issues with re-entrant read locks.
  • APEX Destruction 1.2.3
    • GPU rigid bodies are no longer supported on pre-Fermi hardware.
    • Added actor synchronization filtering by damage event depth and fracture event depth.
    • Added NxDestructibleActor::setDeleteFracturedChunks() to tell a destructible actor to delete its fractured chunks instead of simulating them.
    • Added NxUserDestructibleSyncHandler::onPreProcessReadBegin() and NxUserDestructibleSyncHandler::onPreProcessReadDone() callbacks.
    • Edited NxUserDestructibleSyncHandler::onReadBegin() callback. Removed NxUserDestructibleSyncHandler::onSwizzleDone() callback.
    • Added NxDestructibleActorSyncState struct. Edited NxDestructibleActor::setSyncParams() method.
    • Edited NxDestructibleActor::setHitChunkTrackingParams() method.
    • Added new NxDestructibleAssetStats: maxHullVertexCount, maxHullFaceCount, chunkWithMaxEdgeCount.
    • NxDestructibleAsset::createDestructibleActor() renamed to NxDestructibleAsset::createDestructibleActorFromDeserializedState().
    • NxDestructibleActor::getPartTM() renamed to NxDestructibleActor::getChunkTM().
    • IExplicitHierarchicalMesh::IConvexHull::reduceHull function removes vertices from a convex hull until the given limits are reached (after cooking).
    • Added both the destructible actor pointer and the chunk index to the NxApexPhysX3Interface::setContactReportFlags() callback when PhysX 3.x shapes are created.

NVIDIA is continuing to be a partner for physics middleware on PlayStation 4

with 2 comments

Recent announcement of Sony’s next-generation PlayStation 4 console has revealed that the new gaming system will be equipped with custom AMD GPU, capable of GPGPU computations – for example, physics simulation. To showcase its processing power, a live demo of GPU accelerated particle simulation, running on the Havok engine, was demonstrated during the event.

Update: official press-release

Update #2: PhysX SDK and APEX – now on Xbox One

PS4 logo

An opinions began to emerge, that NVIDIA PhysX SDK engine and PhysX Technology as a whole won’t find its place in the world of next-generation consoles and, thus, will be abandoned quickly.

However, official “PlayStation 4 Tools & Middleware Developers” page says that “following middleware companies have their innovative technology solutions available right now to support PlayStation 4 developers”:

Since NVIDIA does not own any AI or Animation middleware, it is pretty clear that PhysX SDK physics engine is implied here. PhysX SDK will support PlayStation 4 and is already available for developers, as our sources, close to the industry, can confirm.

It is yet unclear, how the situation with GPU acceleration (you know, that “NVIDIA technology running on AMD hardware?!?!” stuff) will be handled on PS4 , but it is now certain – PhysX is here to stay.

Pre-GDC 2013: APEX and PhysX Presentations overview

without comments

Official NVIDIA page for the upcoming Game Developer Conference 2013, which will be held on March 25-29 in San-Francisco, is now online.

Current schedule reveals several presentations, dedicated to APEX and PhysX Technologies. Let’s take a look on what we can expect this year:

March 28th, West Hall, Room #2002

Post Mortem: GPU Accelerated Effects in Borderlands 2

11:15 am - 12:15 pm.

Dane Johnston, Technical Artist, NVIDIA. James Sanders, Director of Visual FX, Gearbox.

Borderlands 2 released to critical acclaim on September 18th, 2012 and showcased a wide variety of NVIDIA CUDA®-accelerated GPU effects. This session will dive into the exact effects that were featured and their benefits to the visual fidelity of the gamer experience.

Side-by-side examples of how GPU-accelerated effects are changing the gaming landscape will be demonstrated in a gaming session. Further examinations into the production process and effects creation will also be explored.

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).

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.
