Detailed Description

This is an "unaligned" LVecBase4.

It has no functionality other than to store numbers, and it will pack them in as tightly as possible, avoiding any SSE2 alignment requirements shared by the primary LVecBase4 class.

Use it only when you need to pack numbers tightly without respect to alignment, and then copy it to a proper LVecBase4 to get actual use from it.

Member Function Documentation

◆ __init__() [1/5]

__init__ ( )

◆ __init__() [2/5]

__init__ ( const LVecBase4f  copy)

◆ __init__() [3/5]

__init__ ( const  UnalignedLVecBase4f)

◆ __init__() [4/5]

__init__ ( float  fill_value)

◆ __init__() [5/5]

__init__ ( float  x,
float  y,

)

◆ fill()

fill ( float  fill_value)

Sets each element of the vector to the indicated fill_value.

This is particularly useful for initializing to zero.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getData()

getData ( )

Returns the address of the first of the three data elements in the vector.

The remaining elements occupy the next positions consecutively in memory.

◆ getNumComponents()

static int getNumComponents ( )
static

◆ operator !=()

bool operator != ( const UnalignedLVecBase4f  other)

◆ operator []() [1/2]

operator [] ( int  i,
float  assign_val 
)

◆ operator []() [2/2]

float operator [] ( int  i)

◆ operator==()

bool operator== ( const UnalignedLVecBase4f  other)

◆ set()

set ( float  x,
