But other programs, e.g. "wsh", are pure X apps in 4.0, and you can use them remotely from non-SGI X servers. [I don't have a complete list of which is which.] The "move to X" was never intended to abandon the Geometry Engine technology or the GL protocol for speaking to it, any more than previous versions of Irix did GL rendering "through" NeWS/4Sight [which they didn't]. X is as pervasive in 4.0 as NeWS was previously, and perhaps even a bit more. But the X protocol simply does not (yet) support the 3-d imaging operations that make so many of the SGI apps what they are today. Until it (or some future protocol standard) does, we'll probably continue to have a mixed GL & X world. -Rob ----- Rob Warnock, MS-1L/515 rpw3@sgi.com rpw3@pei.com Silicon Graphics, Inc.
