XMU555 Structure

A 4D vector with x-,y-, and z- components represented as 5 bit unsigned integer values, and the w-component as a 1 bit integer value.

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

Syntax

struct XMU555  

Remarks

The fields in the XMU555 structure are declared as follows:

struct XMU555
{
    union
    {
        struct
        {
            uint16_t x : 5; // Unsigned 5-bit integer value in the range [0,31] 
                            // describing the x-coordinate of the vector.
            uint16_t y : 5; // Unsigned 5-bit integer value in the range [0,31] 
                            // describing the y-coordinate of the vector.
            uint16_t z : 5; // Unsigned 5-bit integer value in the range [0,31] 
                            // describing the z-coordinate of the vector.
            uint16_t w : 1; // A 1-bit integer value in the range [0,31] 
                            // describing the w-coordinate of the vector.
        };
        uint16_t v; // Unsigned 16-bit short representing the 4D vector.
    };  

XMU555 can be loaded into instances of XMVECTOR by using XMLoadU555.

Instances of XMVECTOR can be stored into an instance of XMU555 with XMStoreU555.
