XMPlaneEqual function (directxmath.h)

  • Article

Determines if two planes are equal.

Syntax

bool XM_CALLCONV XMPlaneEqual(
  [in] FXMVECTOR P1,
  [in] FXMVECTOR P2
) noexcept;

Parameters

[in] P1

XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation

return (P1.x == P2.x && P1.y == P2.y && P1.z == P2.z && P1.w == P2.w);

.

[in] P2

XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation Ax+By+Cz+D=0.

Return value

Returns true if the two planes are equal and false otherwise.

Remarks

The following pseudocode demonstrates the operation of the function.

Ax+By+Cz+D=0
