Description
Gets the distance from the eye point to the 3d world
of the current pixel. This function is useful when
calculating depth effects, which are based on the
pixel depth.
Note, that this function only has a meaningful use when
called from a shader's pixel function. When called from
any other place, the resulting xyz value is undefined.
