Vector4i32 Class Reference

#include <sse_vector_4i32.h>

Detailed Description

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 + 2 + 3 R0 R1 R2 R3
