XMPlaneFromPointNormal function (directxmath.h)
Computes the equation of a plane constructed from a point in the plane and a normal vector.
Syntax
XMVECTOR XM_CALLCONV XMPlaneFromPointNormal(
[in] FXMVECTOR Point,
[in] FXMVECTOR Normal
) noexcept;
Parameters
[in] Point
3D vector describing a point in the plane.
[in] Normal
3D vector normal to the plane.
Return value
Returns a vector whose components are the coefficients of the plane (A, B, C, D) for the plane equation
XMVECTOR Result;
Result.x = Normal.x;
Result.y = Normal.y;
Result.z = Normal.z;
Result.w = -(Point.x * Normal.x + Point.y * Normal.y + Point.z * Normal.z);
return Result;
.
Remarks
The following pseudocode demonstrates the operation of the function:
