Z axis direction and other stuff

[Gary David Bouton]

While reading "Maya 4 Fundamentals", I happened across an interesting point: The Z-axis in modeling programs is not always depth, because some modeling programs grew out of CAD, and a lot of times, the view of a project was from above...IOW, our sense of depth, and this was marked the Y axis. Therefore, the Z axis became height. BTW, Maya can adjust the axes so that Z is anythin g you want. The attched image was done in PIXAR Showplace, actually, and was marked up in XARA, and was used in a book on coordinate systems. Using the right-hand coordinate system, positive rotqation occurs in the direction in which the digits curl.

My Best,

Free education! The Writings Web site
and the updated GaryWorld Gallery is pretty okay, too.
