Article
02/22/2024

Loads data into the x, y, and z components of an XMVECTOR, without type checking.

Note This function is provided for backward compatibility with the Xbox Math library. You should use XMLoadInt3 when you load integer data, and use XMLoadFloat3 when you load floating point data.

Syntax

XMVECTOR XM_CALLCONV XMLoadInt3(
  [in] const uint32_t *pSource
) noexcept;

Parameters

[in] pSource

Address of the data to load.

Return value

Returns an XMVECTOR loaded with the data from the pSource parameter.

Remarks

The w component of the returned XMVECTOR is initialized to 0.

To convert the loaded XMVECTOR into float values, use XMConvertVectorUIntToFloat or XMConvertVectorIntToFloat.

The following pseudocode shows you the operation of the function.

XMVECTOR vectorOut;

uint32_t* pElement = (uint32_t*)pSource;

V.u[0] = pElement[0];
V.u[1] = pElement[1];
V.u[2] = pElement[2];
V.u[3] = 0;

return vectorOut;

Platform Requirements
