Concurrency::direct3d Namespace

The direct3d namespace provides functions that support D3D interoperability. It enables seamless use of D3D resources for compute in AMP code as well as allow use of resources created in AMP in D3D code, without creating redundant intermediate copies. You can incrementally accelerate the compute intensive sections of your DirectX applications by using C++ AMP and use the D3D API on data produced from AMP computations.

Functions

Name	Description
clamp Function	Overloaded. Clamps _X to the specified _Min and _Max range
countbits Function	Counts the number of set bits in _X
firstbithigh Function	Gets the location of the first set bit in _X, starting from the highest order bit and working downward
firstbitlow Function	Gets the location of the first set bit in _X, starting from the lowest order bit and working upward
get_buffer Function	Get the D3D buffer interface underlying an array.
mad Function	Overloaded. Performs an arithmetic multiply/add operation on three arguments: _X * _Y + _Z
make_array Function	Create an array from a D3D buffer interface pointer.
noise Function	Generates a random value by using the Perlin noise algorithm
radians Function	Converts _X from degrees to radians
reversebits Function	Reverses the order of the bits in _X
saturate Function	Clamps _X within the range of 0 to 1
sign Function	Overloaded. Returns the sign of the argument
smoothstep Function	Returns a smooth Hermite interpolation between 0 and 1, if _X is in the range [_Min, _Max].
step Function	Compares two values, returning 0 or 1 based on which value is greater
tile_barrier::wait_with_all_memory_fence Method	Blocks execution of all threads in a tile until all memory accesses have been completed and all threads in the tile have reached this call.
tile_barrier::wait_with_global_memory_fence Method	Blocks execution of all threads in a tile until all global memory accesses have been completed and all threads in the tile have reached this call.
tile_barrier::wait_with_tile_static_memory_fence Method	Blocks execution of all threads in a tile until all tile_static memory accesses have been completed and all threads in the tile have reached this call.
