[−][src]Function directx_math::XMVectorShiftLeft
pub fn XMVectorShiftLeft(
V1: FXMVECTOR,
V2: FXMVECTOR,
Elements: u32
) -> XMVECTOR
Shifts a vector left by a given number of 32-bit elements, filling the vacated elements with elements from a second vector.
Parameters
V1
Vector to shift left.
V2
Vector used to fill in the vacated components of V1
after it is shifted left.
Elements
Number of 32-bit elements by which to shift V
left. This parameter must be 0, 1, 2, or 3.
Return value
Returns the shifted and filled in XMVECTOR.
Remarks
The following code demonstrates how this function might be used.
XMVECTOR v1 = XMVectorSet( 10.0f, 20.0f, 30.0f, 40.0f );
XMVECTOR v2 = XMVectorSet( 50.0f, 60.0f, 70.0f, 80.0f );
XMVECTOR result = XMVectorShiftLeft( v1, v2, 1 );
The shifted vector (result) will be <20.0
, 30.0
, 40.0
, 50.0
>.
In the case of a constant shift value, it is more efficent to use the template form of XMVectorShiftLeft:
