2399// ======================================
2400// Drawing functions. These functions allow the visualization in several ways
2401// of the volumes defined in the geometrical data structure. It is possible
2402// to draw the logical tree of volumes belonging to the detector (DTREE),
2403// to show their geometrical specification (DSPEC,DFSPC), to draw them
2404// and their cut views (DRAW, DCUT). Moreover, it is possible to execute
2405// these commands when the hidden line removal option is activated; in
2406// this case, the volumes can be also either translated in the space
2407// (SHIFT), or clipped by boolean operation (CVOL). In addition, it is
2408// possible to fill the surfaces of the volumes
2409// with solid colours when the shading option (SHAD) is activated.
2410// Several tools (ZOOM, LENS) have been developed to zoom detailed parts
2411// of the detectors or to scan physical events as well.
2412// Finally, the command MOVE will allow the rotation, translation and zooming
2413// on real time parts of the detectors or tracks and hits of a simulated event.
2414// Ray-tracing commands. In case the command (DOPT RAYT ON) is executed,
2415// the drawing is performed by the Geant ray-tracing;
2416// automatically, the color is assigned according to the tracking medium of each
2417// volume and the volumes with a density lower/equal than the air are considered
2418// transparent; if the option (USER) is set (ON) (again via the command (DOPT)),
2419// the user can set color and visibility for the desired volumes via the command
2420// (SATT), as usual, relatively to the attributes (COLO) and (SEEN).
2421// The resolution can be set via the command (SATT * FILL VALUE), where (VALUE)
2422// is the ratio between the number of pixels drawn and 20 (user coordinates).
2423// Parallel view and perspective view are possible (DOPT PROJ PARA/PERS); in the
2424// first case, we assume that the first mother volume of the tree is a box with
2425// dimensions 10000 X 10000 X 10000 cm and the view point (infinetely far) is
2426// 5000 cm far from the origin along the Z axis of the user coordinates; in the
2427// second case, the distance between the observer and the origin of the world
2428// reference system is set in cm by the command (PERSP NAME VALUE); grand-angle
2429// or telescopic effects can be achieved changing the scale factors in the command
2430// (DRAW). When the final picture does not occupy the full window,
2431// mapping the space before tracing can speed up the drawing, but can also
2432// produce less precise results; values from 1 to 4 are allowed in the command
2433// (DOPT MAPP VALUE), the mapping being more precise for increasing (VALUE); for
2434// (VALUE = 0) no mapping is performed (therefore max precision and lowest speed).
2435// The command (VALCUT) allows the cutting of the detector by three planes
2436// ortogonal to the x,y,z axis. The attribute (LSTY) can be set by the command
2437// SATT for any desired volume and can assume values from 0 to 7; it determines
2438// the different light processing to be performed for different materials:
2439// 0 = dark-matt, 1 = bright-matt, 2 = plastic, 3 = ceramic, 4 = rough-metals,
2440// 5 = shiny-metals, 6 = glass, 7 = mirror. The detector is assumed to be in the
2441// dark, the ambient light luminosity is 0.2 for each basic hue (the saturation
2442// is 0.9) and the observer is assumed to have a light source (therefore he will
2443// produce parallel light in the case of parallel view and point-like-source
2444// light in the case of perspective view).
