XMUBYTE4 Structure

Describes a 4D vector where each component is a unsigned integer, 8-bits (1 byte) in length.

A 4D vector where each component is a unsigned integer, 8-bits (1 byte) in length.

If you are programming in C++, you can use the constructors and operator methods of this structure.

Note See DirectXMath Library Type Equivalences for information about equivalent D3DDECLTYPE, D3DFORMAT, and DXGI_FORMAT objects.

Syntax

struct XMUBYTE4

Remarks

The fields in the XMUBYTE4 structure are declared as follows:

struct XMUBYTE4
{
    union
    {
        struct
        {
            uint8_t x; // Unsigned 8-bit integer value in the range [0, 255] 
                       // describing the x-coordinate of the vector.
            uint8_t y; // Unsigned 8-bit integer value in the range [0, 255] 
                       // describing the y-coordinate of the vector.
            uint8_t z; // Unsigned 8-bit integer value in the range [0, 255] 
                       // describing the z-coordinate of the vector.
            uint8_t w; // Unsigned 8-bit integer value in the range [0, 255] 
                       // describing the w-coordinate of the vector.
        };
        uint32_t v; // Unsigned 32-bit 8-bit integer representing the 4D vector.
    };

XMUBYTE4 can be loaded into instances of XMVECTOR by using XMLoadUByte4.

Instances of XMVECTOR can be stored into an instance of XMUBYTE4 with XMStoreUByte4.
