Calculates the dot product between an input plane and a 4D vector.
- P [in]
XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation
- V [in]
4D vector to use in the dot product.
Returns the dot product of P and V replicated into each of the four components of the returned XMVECTOR.
The XMPlaneDot function is useful for determining the plane's relationship with a homogeneous coordinate. For example, this function can be used to determine if a particular coordinate is on a particular plane, or on which side of a particular plane a particular coordinate lies.
