AxonVR is bringing lifelike touch to digital experiences through advanced haptic technology. The heart of AxonVR?s platform is HaptX, a haptic textile that lets users feel the physical properties of virtual objects. This includes texture, shape, motion, vibration and temperature.
...
AxonVR built its haptic engine on top of NVIDIA PhysX

Recently CGIcoffee.com blog author Armen Barsegyan conducted two studies involving NVIDIA FleX with two main goals: to see how FleX could be integrated into a Digital Content Creation package (in this case - Autodesk Softimage) and whether it could speed up such routine tasks as cloth and fluid simulation for production work.

What's new in Unity 5.6

...
Physics: Physics Debug

    A tool designed to provide a visualization of what is going on in our physics middleware (PhysX), allowing you to quickly inspect the Collider geometry in your Scene, and profile common physics-based scenarios.
        Also serves as a profiling tool, because it can hide all sleeping Rigidbody components and show all concave Mesh Colliders.

Stand-alone driver for rigs that ain't compatible with GeForce driver 381.65

 

   Release Highlights
     

        THE ONLY CHANGE in this version 9.17.0329 from 9.16.0328 is that this version has new digital signatures on all of the DLLs. Both SAH1 and SHA256 signatures are present.
        Includes the latest PhysX runtime builds to support all released PhysX content.
        Changes & fixed issues in this release
            Adds Support for 1000 series GPUs for Batman Arkham Knight.
        Supports NVIDIA PhysX acceleration on all GeForce 9‑series, and 100‑series to 900‑series GPUs with a minimum of 256MB dedicated graphics memory.
        Note: Some applications may have higher minimum requirements.
        Supports NVIDIA PhysX acceleration on GeForce for SDK versions 2.7.1, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 2.8.0, 2.8.1, 2.8.3 and 2.8.4.
        Supports control of your GPU PhysX configuration from the NVIDIA display driver control panel.
        Note: For games that use SDK versions before 2.7.1 the PhysX Legacy Installer must also be installed. These are games that were released around the end of 2007 or earlier. (AGEIA titles) Examples of these games include CellFactor, Clive baker?s Jerich, Gears of War, Pirates of the Burning Sea, Switchball and Velvet Assassin. The PhysX Legacy Installer is available here: PhysX_System_Software_Legacy_Driver

1.2.0 (beta)
------------

- New API to retrieve particle neighbor information, see NvFlexGetNeighbors()
- New API to support shape collision filtering, collision channels can be assigned to particles and shapes to specify which pairs collide, see NvFlexPhase
- New API to support per-shape plastic deformation, it is now possible to specify plastic creep and threshold coefficient on a per-shape basis (previous global settings), see NvFlexSetRigids()
- New API to selectively disable solver features, this can lead to improved performance, see NvFlexFeatureMode, replaces global FlexParams::fluid option
- New API to allow sub-range particle buffer updates, see NvFlexCopyDesc
- New API for asynchronous compute, see NvFlexInitDesc
- Fix for unnecessary synchronization when calling NvFlexMap() on a device buffer
- Fix numerical precision for shape-matching constraints with large coordinates
- Fix for uninitialized contact indices returned from NvFlexGetContacts() if NvFlexUpdateSolver() has not been called
- Fix for SDF collision in D3D12
- Fix for D3D warning when using NvFlexSetRigids()
- Add D3D12 rendering support to the demo
- Add support for device NvFlexBuffers on D3D
- Enable NvToolkit profiling zones so to provide annotations in NSight profiles by default

Known Issues
------------

- Demo rendering artifacts in D3D12 fullscreen on AMD platforms
- NvFlexGetTimers() may report incorrect values on D3D12
- Crash on inflatable test scenes on some Kepler class GPUs

    This version of the PhysX System software fixes an issue in the PhysX Loader that caused some games using PhysX 2.7.1 SDK (very old) to fail with the new GPU driver.
    Includes the latest PhysX runtime builds to support all released PhysX content.
    Supports NVIDIA PhysX acceleration on all GeForce 9‑series, and 100‑series to 1000‑series GPUs with a minimum of 256MB dedicated graphics memory.
    Note: Some applications may have higher minimum requirements.
    Supports NVIDIA PhysX acceleration on GeForce for SDK versions 2.7.1, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 2.8.0, 2.8.1, 2.8.3, 2.8.4, and above.
    Supports control of your GPU PhysX configuration from the NVIDIA display driver control panel.
    Note: For games that use SDK versions before 2.7.1 the PhysX Legacy Installer must also be installed. These are games that were released around the end of 2007 or earlier.
