Vector2f64 Class Reference

#include <sse_vector_2f64.h>

详细描述

The class and the default constructor are always defined. The functions of this class are only defined when C4D_HAS_SSE2_CAPABILITY is set. Instances of this class must be aligned to 16 bytes. The layout in the memory is as follows: address + 0 + 1 R0 R1

◆  Vector2f64() [2/3]

MAXON_ATTRIBUTE_FORCE_INLINE Vector2f64 ( Float64   d0 ,
Float64   d1  
)
explicit

Constructs the object and sets all values to f0...f3.

参数
[in] d0 The value that is assigned to vector element 0.
[in] d1 The value that is assigned to vector element 1.

◆  Vector2f64() [3/3]

MAXON_ATTRIBUTE_FORCE_INLINE Vector2f64 ( const Float64 *  p ,
Bool   aligned  
)
explicit

Constructs a vector from an address in the memory.

参数
[in] p The address where the vector is loaded from.
[in] aligned Should be set to true, if #p is known to be 16-byte aligned.

◆  LoadUnaligned()

MAXON_ATTRIBUTE_FORCE_INLINE void LoadUnaligned ( const Float64 *  p )

Loads a vector from an address in the memory.

参数
[in] p The address where the vector is loaded from.

◆  LoadAligned()

MAXON_ATTRIBUTE_FORCE_INLINE void LoadAligned ( const Float64 *  p )

Loads a vector from an address in the memory.

参数
[in] p The address where the vector is loaded from. It must be 16-byte aligned.

◆  LoadSingle()

MAXON_ATTRIBUTE_FORCE_INLINE void LoadSingle ( const double *  p )

Loads a single value from an address in the memory to the lower value of the vector. The upper part is set to zero.

参数
[in] p The address where the vector is loaded from.

◆  Shuffle()

static MAXON_ATTRIBUTE_FORCE_INLINE Vector2f64 Shuffle ( const Vector2f64 &  a )
static

Shuffles the components of the input vectors. Note that the template arguments must be numeric constants and be either 0 or 1.

参数
[in] a Input vector A.
Template Parameters
ma1 Decides which element of vector A becomes the new R0.
mb1 Decides which element of vector B becomes the new R0.
返回
A vector consisting of R0=A[ma1], R1=B[mb1]
