Points inside a tetrahedral

  1. Jul 14, 2008 #1
    Hello ,
    does anybody knows how can I check if a point is inside a tetrahedral. The tetrahedral isn't regular.

    I don't know if this is a good way to solve it. But if in a triangle, the easiest way to check if a point is inside is to check the sum of the area. i.e. for ABC, there is a point P, if P is inside ABC, then, area(ABP)+area(ACP)+area(BCP) = area(ABC).

    You can check the volume in the tetrahedral case.
