D3PLOT 22.1
The "X" (X_Windows) 2-D Protocol
The "X" (X_Windows) 2-D protocol
X_Windows is the most widely supported graphics protocol on modern engineering work-stations. It has the following attributes:
| It uses a client/server mode of working that makes it network transparent. That is you can display results on one machine (the server), while actually running on another, (the client). Client and server may be totally different machines connected by a network, or indeed the same machine working autonomously. | |
| It supports a wide range of screen types. Almost any graphics screen of any resolution and type will work under this protocol. | |
| It integrates well with window managers. All current workstation window managers will support multiple "X" windows. | |
|
It is two dimensional only. (The PEX 3D extension has proved unsuccessful in the face of competition from OpenGL.) |
The D3PLOT screen menu is an X-Window, a child of the window manager, and it has its own children that it manages locally.
The menu system always uses the default visual of the screen so that, in itself, it will not clash with other applications. The graphics sub-window within this menu may also be invoked with the default visual, or with a different one.
X "visuals" are discussed in the next section.
