protected

Find the intersections between a line passing through Point and parallel to the Z axis and the given mesh, then return the lowest and highest of those intersections.

Parameters

Mesh	The mesh with which to perform the intersection test
Point	The point through which the line passes through (the z component is redundant)
dMinZ	The returned lowest intersection point
dMaxZ	The returned highest intersection point
bForceFind	Force the algorithm to find at least one intersection, what this means is that it will find the intersection with the closest triangle and use that intersection as the maximum and minimum returned bounds. This is usefull for cases where the vertical line just misses the mesh and the closest intersection is needed.
