NAME

arch − display a simulated architectural model

SYNOPSIS

/usr/people/demos/arch

/usr/people/mexdemos/arch

DESCRIPTION

arch displays a model of an imaginary city block.  Operator controls adjust the viewing position and select one or several structures for display. 

Most of the user interface is through the mouse buttons.  Each non-zero combination of mouse buttons causes a different viewpoint movement.  The mouse valuators are ignored. 

In the initial state, a single building is displayed.  Typing keys create different actions. 

Key Function
sturn on (or off) wireframe buildings that complete the block
f cover (or uncover) building surfaces
mturn on (or off) automatic movement around the city
r initialize the program
h show help menu (does not work in window manager)
ESC exit the program

DISPLAY OPTIONS

Upon entry into the program, arch is set for NTSC or high resolution output, depending on the currently selected monitor.  The display monitor can be altered during program execution by pressing the proper control character.

WINDOW MANAGER

The window manager version of usr/people/mexdemos/arch runs without the aforementioned display options.  If the site is in constant motion, it stays in motion, even if the window is detached.  The multiple display options (60-Hz, 30-Hz, NTSC and PAL) are not available for the window manager version. There is no help menu in the window manager version of arch. Raster fonts do not scale to arbitrarily sized windows.
