• Fixed PS4 mising override error.
• Fix setCapsules bug.

New: - Authoring library (helper functions useful for authoring tools)

Known issues: - None

1.1.4

Fixed:

• DirectX 11 solver had issues with ccd sphere/capsule collision.
• Fixed sphere collision detection issue when clothing AABB is (almost) completely flat.
• Fix virtual particle collision issue on cuda (static particles could be moved)
• Enabled namespace in simd library, fixed runtime issues on switch when linking with APEX or PhysX.

New:

• Removed old cuda architectures that are not supported anymore
• Added improved teleportation API, rotation support and better support for teleporting while moving
• Virtual particle collision detection is now implemented in DX11 as well (DX11 was the only solver lacking it)

Known issues: - None

1.1.3

Supported platforms:

• Windows (CPU, CUDA, DX11)
• Mac (beta, tested on Sierra)
• Linux (beta, tested on Ubuntu 16.04.1 LTS x64)
• PlayStation 4 (beta) with PS4 SDK 4.5
• Xbox one (CPU, DX11, beta)
• Android (arm64-v8a, API >= 21), tested on Shield TV

Note: beta platforms are not yet optimized.

Supported compilers (via cmake 3.7)

• Windows: Visual Studio 12, 14 (2013, 2015)
• Linux: gcc 5.4 (only x64)
• Mac: xcode
• PlayStation 4: Visual studio 14 (2015)
• Xbox one: Visual studio 14 (2015)
• Android: NDK r12b and above

Fixed:

• Incorrect assertion in ClothImpl::setFluidDensity.
• Make the simulation with MultithreadedSolverHelper work when no cloth present in the solver.
• Correct number of simulation chunks calculation for DX11/CUDA solvers when no cloths were added to the solver.
• Cuda wind simulation crashed on older hardware.
• Internal simd library now lives inside the nv::cloth namespace to avoid issues when statically linked with PhysX.

New:

• Introduce addCloths() method for all the solvers, which allows to perform a fast batch addition of multiple cloths.
• Cuda support on linux (experimental)
• Android support

Known issues: - DirectX 11 solver has issues with ccd sphere/capsule collision.

1.1.2

Fixed:

• Dynamic allocations at runtime removed from MovingAverage.
• Possible error when starting samples due to gpu incompatible with dx debug mode.

New:

• Added cmake flags to disable dx11 and/or cuda support.

Known issues: - DirectX 11 solver has issues with ccd sphere/capsule collision.

1.1.1

Fixed:

• Air drag/lift did react to flow speed only linearly, model was changed to be more physically correct.
• Fixed issue where scaling units would result in different air drag/lift behavior (by adding fluid density parameter).
• Fixed “unused typedef __t100” warning in xcode.

Known issues: - DirectX 11 solver has issues with ccd sphere/capsule collision.

1.1.0

Fixed:

• DirectX 11 solver now supports triangle collision shapes and air drag/lift.
• Fixed bug where changing friction on cloth already in simulation would cause assert or crash.
• Optimization flag now working on PS4 release build.

New:

• Solver::getNumCloths and Solver::getClothList interface.
• Improved samples (new scenes and debug visualization)

Known issues: - DirectX 11 solver has issues with ccd sphere/capsule collision.

1.0.0

Known issues: - DirectX 11 solver doesn’t support triangle collision shapes and air drag/lift
