Plane::IsOnPositiveSide

Syntax

bool Plane::IsOnPositiveSide(const float4 &point) const; [4 lines of code]

Tests if the given point lies on the positive side of this plane.

A plane divides the space in three sets: the negative halfspace, the plane itself, and the positive halfspace. The normal vector of the plane points towards the positive halfspace.

Return Value

This function returns true if the given point lies either on this plane itself, or in the positive halfspace of this plane.
