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.

Members

Classes

Name	Description
scoped_d3d_access_lock Class	An RAII wrapper for a D3D access lock on an accelerator_view object.

Structures

Name	Description
adopt_d3d_access_lock_t Structure	Tag type to indicate the D3D access lock should be adopted rather than acquired.

Functions

Name	Description
abs Function	Returns the absolute value of the argument
clamp Function	Overloaded. Clamps _X to the specified _Min and _Max range
countbits Function	Counts the number of set bits in _X
create_accelerator_view Function	Creates an accelerator_view Class from a pointer to a Direct3D device interface
d3d_access_lock Function	Acquires a lock on an accelerator_view for the purpose of safely performing D3D operations on resources shared with the accelerator_view
d3d_access_try_lock Function	Attempt to acquire the D3D access lock on an accelerator_view without blocking.
d3d_access_unlock Function	Release the D3D access lock on the given accelerator_view.
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.
imax Function	Compares two values, returning the value which is greater.
imin Function	Compares two values, returning the value which is smaller.
is_timeout_disabled Function	Returns a boolean flag indicating if timeout is disabled for the specified accelerator_view.
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
rcp Function	Calculates a fast, approximate reciprocal of the argument
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
umax Function	Compares two unsigned values, returning the value which is greater.
umin Function	Compares two unsigned values, returning the value which is smaller.
