XMUNIBBLE4 Structure

A 4D vector with four unsigned 4-bit integer components.

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

Syntax

struct XMUNIBBLE4

Remarks

The fields in the XMUNIBBLE4 structure are declared as follows:

struct XMUNIBBLE4
{
    union
    {
        struct
        {
            uint16_t x : 4; // Unsigned 4-bit integer value in the range [0,15] 
                            // describing the x-coordinate of the vector. 
                            // The 4-bit x component.
            uint16_t y : 4; // Unsigned 4-bit integer value in the range [0,15] 
                            // describing the y-coordinate of the vector. 
                            // The 4-bit y component.
            uint16_t z : 4; // Unsigned 4-bit integer value in the range [0,15] 
                            // describing the z-coordinate of the vector. 
                            // The 4-bit z component.
            uint16_t w : 4; // Unsigned 4-bit integer value in the range [0,15] 
                            // describing the w-coordinate of the vector. 
                            // The 4-bit w component.
        };
        uint16_t v; // Unsigned 16-bit short representing the 4D vector in a packed format.
    };

XMUNIBBLE4 can be loaded into instances of XMVECTOR by using XMLoadUNibble4.

Instances of XMVECTOR can be stored into an instance of XMUNIBBLE4 with XMStoreUNibble4.
