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

◆ get_data()

const double * UnalignedLVecBase4d::get_data ( ) const
inline

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

The remaining elements occupy the next positions consecutively in memory.

Definition at line 3154 of file lvecBase4.h.

◆ get_num_components()

int UnalignedLVecBase4d::get_num_components ( ) const
inline

Returns the number of elements in the vector, 4.

Definition at line 3164 of file lvecBase4.h.

◆ size()

int UnalignedLVecBase4d::size ( )
inlinestatic

Returns 4: the number of components of a LVecBase4.
