XMVectorIsInfinite function (directxmath.h)
Performs a per-component test for +/- infinity on a vector.
Syntax
XMVECTOR XM_CALLCONV XMVectorIsInfinite(
[in] FXMVECTOR V
) noexcept;
Parameters
[in] V
Vector to test.
Return value
Returns a vector containing the results of each component test.
Remarks
The following pseudocode demonstrates the operation of the function:
XMVECTOR Result;
Result.x = (V.x == +infinity || V.x == -infinity) ? 0xFFFFFFFF : 0;
Result.y = (V.y == +infinity || V.y == -infinity) ? 0xFFFFFFFF : 0;
Result.z = (V.z == +infinity || V.z == -infinity) ? 0xFFFFFFFF : 0;
Result.w = (V.w == +infinity || V.w == -infinity) ? 0xFFFFFFFF : 0;
return Result;
