A pair test is a type of test between two [[Geometric Primitive]]. There are two types of pair tests, Inclusivity and Exclusivity. ### Inclusivity For some two primitives $A,B$ is: - $A \subseteq B$ A is fully contained by B - $\exists x : x \in A,B$ A is overlapping with B - [[Intersection]] points between B ### Exclusivity The inverse of inclusivity, used for: - [[Culling]] - [[Clipping]]
