NVIDIA FleX Changelog

What's new in NVIDIA FleX 1.1.0

• New API style, for consistency with other products the API has now an NvFlex prefix and follows a naming convention similar to PhysX
• Add support for DirectX, in addition to CUDA there is now a cross platform DirectX 11 and 12 version of the Flex libraries that Windows applications can link against
• Add support for max acceleration clamping, see NvFlexParams::maxAcceleration, can be useful to reduce popping with fast moving kinematic shapes and large interpenetration
• Add support to querying compute device, see NvFlexGetDeviceName()
• Add support for flushing compute queue, see NvFlexFlush()
• Add support for multiple library instances, NvFlexInit() now returns a library which is bound to a single compute device
• Add support for local space particle simulation, see NvFlexExtMovingFrameInit() and two new local space fluid and cloth demos
• Add support for CUDA 8.0.44
• Remove NvFlexError enum, errors will be reported through the NvFlexErrorCallback passed to NvFlexInit()
• Remove NvFlexMemory enum, users should use the new NvFlexBufferType
• Fix bug in inflatable constraint solver that could cause some shapes to generate NaNs
• Fix for SDF contact generation when the particle lies completely outside volume, fixes a problem with ghost contacts
• Fix for friction being incorrectly applied on trigger shapes
• Fix for multi-phase fluid cohesion not working correctly, re-enable Rayleigh-Taylor instability test
• Fix bug with public projects that referenced internal CUDA paths
• Fix for calling NvFlexSetInflatables() with a count of zero
• Fix for buoyancy parameter
• Fix for bug in BVH builder that could cause missed collisions
• New optional NvFlexDevice library for handling GPU selection and initialization in CUDA
• New buffer based API, all data must now be passed to Flex through FlexBuffers created through NvFlexAllocBuffer()
• New stable shape matching code for more robust and efficient soft bodies, removes need for NvFlexParams::inertiaBias
• New collision shape API supports instancing of convex meshes and a much simplified API, see NvFlexSetShapes()
• Improvements to collision detection for moving shapes, Flex will now perform a CCD check also taking into account the shape trajectory using the prev/current transforms of each shape
