2375// ======================================
2376// Drawing functions. These functions allow the visualization in several ways
2377// of the volumes defined in the geometrical data structure. It is possible
2378// to draw the logical tree of volumes belonging to the detector (DTREE),
2379// to show their geometrical specification (DSPEC,DFSPC), to draw them
2380// and their cut views (DRAW, DCUT). Moreover, it is possible to execute
2381// these commands when the hidden line removal option is activated; in
2382// this case, the volumes can be also either translated in the space
2383// (SHIFT), or clipped by boolean operation (CVOL). In addition, it is
2384// possible to fill the surfaces of the volumes
2385// with solid colours when the shading option (SHAD) is activated.
2386// Several tools (ZOOM, LENS) have been developed to zoom detailed parts
2387// of the detectors or to scan physical events as well.
2388// Finally, the command MOVE will allow the rotation, translation and zooming
2389// on real time parts of the detectors or tracks and hits of a simulated event.
2390// Ray-tracing commands. In case the command (DOPT RAYT ON) is executed,
2391// the drawing is performed by the Geant ray-tracing;
2392// automatically, the color is assigned according to the tracking medium of each
2393// volume and the volumes with a density lower/equal than the air are considered
2394// transparent; if the option (USER) is set (ON) (again via the command (DOPT)),
2395// the user can set color and visibility for the desired volumes via the command
2396// (SATT), as usual, relatively to the attributes (COLO) and (SEEN).
2397// The resolution can be set via the command (SATT * FILL VALUE), where (VALUE)
2398// is the ratio between the number of pixels drawn and 20 (user coordinates).
2399// Parallel view and perspective view are possible (DOPT PROJ PARA/PERS); in the
2400// first case, we assume that the first mother volume of the tree is a box with
2401// dimensions 10000 X 10000 X 10000 cm and the view point (infinetely far) is
2402// 5000 cm far from the origin along the Z axis of the user coordinates; in the
2403// second case, the distance between the observer and the origin of the world
2404// reference system is set in cm by the command (PERSP NAME VALUE); grand-angle
2405// or telescopic effects can be achieved changing the scale factors in the command
2406// (DRAW). When the final picture does not occupy the full window,
2407// mapping the space before tracing can speed up the drawing, but can also
2408// produce less precise results; values from 1 to 4 are allowed in the command
2409// (DOPT MAPP VALUE), the mapping being more precise for increasing (VALUE); for
2410// (VALUE = 0) no mapping is performed (therefore max precision and lowest speed).
2411// The command (VALCUT) allows the cutting of the detector by three planes
2412// ortogonal to the x,y,z axis. The attribute (LSTY) can be set by the command
2413// SATT for any desired volume and can assume values from 0 to 7; it determines
2414// the different light processing to be performed for different materials:
2415// 0 = dark-matt, 1 = bright-matt, 2 = plastic, 3 = ceramic, 4 = rough-metals,
2416// 5 = shiny-metals, 6 = glass, 7 = mirror. The detector is assumed to be in the
2417// dark, the ambient light luminosity is 0.2 for each basic hue (the saturation
2418// is 0.9) and the observer is assumed to have a light source (therefore he will
2419// produce parallel light in the case of parallel view and point-like-source
2420// light in the case of perspective view).
