XMPlaneNearEqual function (directxmath.h)
Determines whether two planes are nearly equal.
Syntax
bool XM_CALLCONV XMPlaneNearEqual(
[in] FXMVECTOR P1,
[in] FXMVECTOR P2,
[in] FXMVECTOR Epsilon
) noexcept;
Parameters
[in] P1
XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation Ax+By+Cz+D=0.
[in] P2
XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation Ax+By+Cz+D=0.
[in] Epsilon
An XMVECTOR that gives the component-wise tolerance to use when comparing P1 and P2.
Return value
Returns true if P1 is nearly equal to P2 and false otherwise.
Remarks
The XMPlaneNearEqual function normalizes the P1 and P2 parameters before passing them, and the Epsilon parameter, to the XMVector4NearEqual function. For more information about how the calculation is performed, see the XMVector4NearEqual function.
