Facility Vulnerability with VISAC

Facility Geometry Viewers

In addition to the geometry editor Edificio, VISAC has a set of viewers to provide detailed views in both 2D and 3D. These are used for viewing the facility geometry models as well as viewing the damage results from incidents.

	Name	Description
	2D Triple View Slicer	Shows three section views, like a standard engineering drawing.
	QuickView 3D	Interactive scengraph viewer. Approximates curved surfaces with sets of planes.
	3D Ray Tracer	Precision renderer for presentation-quality graphics.
	Topographic Viewer	Used for terrain contour maps and elevation shading maps.

These viewers all have similar menu structures and display VISAC models using a standard color scheme:

BRL Code	Color	Material
100-199	pink	air
200-299	green	soil
500-599	gray	concrete
600-699	yellow	rebar steel
700-799	light gray	rock rubble
800-899	blue	steel plate
900-999	red	critical components
911	cyan	broken critical components
111	dark gray	holes generated by QuickBlast
---	very light gray	interiors of basic models

In these viewers, the colors for each material type present can also be selected by the user by using the 'Geometry' menu, 'Materials/Colors' option.

The 'File' menu in any of the viewers allows the geometry to be exported or the current image to be saved.

'Export Geometry' option - writes out the geometry information in a variety of formats, including BRL-CAD, WaveFront and Unreal Tournament.
'Save Image as JPEG' - creates a *.jpeg file for the current view.
'Copy Image to Clipboard' - copies the current image to the system clipboard, which can then be pasted into other programs, such as MS Word.
