[java] 3d keyword
Author
I was just browsing somebody else's source code so I could figure out how to implement csg when I saw this
does anybody know what the 3d keyword means?
the 3d keyword mean that the point is in a 3 dimensional plane, not only does it have an x and y axis but a z axis as well.
D or d indicates that the number is a double precision floating point number.
He could have used 3.0 instead, but 3d was funnier i suppose.

it's not a keyword ... it means they're dividing by 3 as an double rather than a float or integer. I forget the exact name of the letter, but put "f" after values you want treated as floats
