/*
* Much math isn't it. Well here is what it does.
* We can't use Sins.GetVertexHeight to get height info because it is used for vertex and a joint have a very big probability of not perpeticular on a vertice.
* First find which triangle the joint falls under. To do that we floor and ceil both x and z coordinates of joint's position.
* p1 and p2 of triangle always will be (xFloor, y, zCeil) and (xCeil, y, zFloor). p3 will be closest one of (xFloor, y, zFloor) or (xCeil, y, zFloor)
* Then find which point on triangle joint falls under. Just find out of triangle's plane equation using triangle's normal then using these equation and x, z positions find out y position.
