my question is why it is named "cone" metric space .Is there any geometrical meaning for that ..one thing that cone is in three dimensional . but we can define cone metric space for any set with co-domain is real banach and cone in that.

whether cone in three dimensional is projected to two dimensional

 I'm afraid your question is not appropriate for this site, so I'm closing it. In mathematics, the word "cone" is not restricted to three dimensional objects. – S. Carnahan♦ Jan 24 2011 at 14:43

 Or, it sure doesn't look appropriate. You might have more success on Math Overflow if you took more trouble with formulating your question; the phrases "one thing that cone is in three dimensional" and "whether cone in three dimensional is projected to two dimensional" are ungrammatical, and seem close to gibberish. A quick answer to your first question is that it's a set with a distance function which is valued in a real Banach space E which is partially ordered with respect to a cone in E, or so I gather after a quick consultation with google. Seems pretty straightforward to me. – Todd Trimble Jan 24 2011 at 14:51
