14\ingroup Geometry_classes
15
16Geometry checking package.
17
18TGeoChecker class provides several geometry checking methods. There are two
19types of tests that can be performed. One is based on random sampling or
20ray-tracing and provides a visual check on how navigation methods work for
21a given geometry. The second actually checks the validity of the geometry
22definition in terms of overlapping/extruding objects. Both types of checks
23can be done for a given branch (starting with a given volume) as well as for
24the geometry as a whole.
25
26#### TGeoChecker::CheckPoint(Double_t x, Double_t y, Double_t z)
27
28This method can be called directly from the TGeoManager class and print a
29report on how a given point is classified by the modeller: which is the
30full path to the deepest node containing it, and the (under)estimation
31of the distance to the closest boundary (safety).
32
33#### TGeoChecker::RandomPoints(Int_t npoints)
34
35Can be called from TGeoVolume class. It first draws the volume and its
36content with the current visualization settings. Then randomly samples points
37in its bounding box, plotting in the geometry display only the points
38classified as belonging to visible volumes.
39
40#### TGeoChecker::RandomRays(Int_t nrays, Double_t startx, starty, startz)
41
42Can be called and acts in the same way as the previous, but instead of points,
43rays having random isotropic directions are generated from the given point.
44A raytracing algorithm propagates all rays until they exit geometry, plotting
45all segments crossing visible nodes in the same color as these.
46
47#### TGeoChecker::Test(Int_t npoints)
48
49Implementation of TGeoManager::Test(). Computes the time for the modeller
50to find out "Where am I?" for a given number of random points.
51
52#### TGeoChecker::LegoPlot(ntheta, themin, themax, nphi, phimin, phimax,...)
53
54Implementation of TGeoVolume::LegoPlot(). Draws a spherical radiation length
55lego plot for a given volume, in a given theta/phi range.
56
57#### TGeoChecker::Weight(Double_t precision)
58
59Implementation of TGeoVolume::Weight(). Estimates the total weight of a given
60volume by material sampling. Accepts as input the desired precision.
