Base abstract class for all shapes.
Shapes are geometrical objects that provide the basic modelling functionality. They provide the definition of the LOCAL frame of coordinates, with respect to which they are defined. Any implementation of a shape deriving from the base TGeoShape class has to provide methods for :
The modeler currently provides a set of 16 basic shapes, which we will call primitives. It also provides a special class allowing the creation of shapes made as a result of boolean operations between primitives. These are called composite shapes and the composition operation can be recursive (composition of composites). This allows the creation of a quite large number of different shape topologies and combinations.
Named shapes register themselves to the manager class at creation time. The manager is responsible for their final deletion. Shapes can be created using their default constructor if their retrieval by name is not needed, but in this case they are owned by the user. A shape may be referenced by several volumes, therefore its deletion is not possible once volumes were defined based on it.
Shape objects embed only the minimum set of parameters that are fully describing a valid physical shape. For instance, a tube is represented by its half length, the minimum radius and the maximum radius. Shapes are used together with media in order to create volumes, which in their turn are the main components of the geometrical tree. A specific shape can be created stand-alone :
Sometimes it is much easier to create a volume having a given shape in one step, since shapes are not directly linked in the geometrical tree but volumes are :
Note that global queries related to a geometry are handled by the manager class. However, shape-related queries might be sometimes useful.
Bool_t TGeoShape::Contains(const Double_t *point[3])
this method returns true if POINT is actually inside the shape. The point has to be defined in the local shape reference. For instance, for a box having DX, DY and DZ half-lengths a point will be considered inside if :
Double_t TGeoShape::DistFromInside(Double_t *point[3], Double_t *dir[3], Int_t iact, Double_t step, Double_t *safe)
computes the distance to exiting a shape from a given point INSIDE, along a given direction. The direction is given by its director cosines with respect to the local shape coordinate system. This method provides additional information according the value of IACT input parameter :
Double_t TGeoShape::DistFromOutside(Double_t *point[3], Double_t *dir[3], Int_t iact, Double_t step, Double_t *safe)
computes the distance to entering a shape from a given point OUTSIDE. Acts in the same way as B).
Double_t Safety(const Double_t *point[3], Bool_t inside)
compute maximum shift of a point in any direction that does not change its INSIDE/OUTSIDE state (does not cross shape boundaries). The state of the point have to be properly supplied.
Double_t *Normal(Double_t *point[3], Double_t *dir[3], Bool_t inside)
returns director cosines of normal to the crossed shape surface from a given point towards a direction. One has to specify if the point is inside or outside shape. According to this, the normal will be outwards or inwards shape respectively. Normal components are statically stored by shape class, so it has to be copied after retrieval in a different array.
Shapes can generally be divided along a given axis. Supported axis are X, Y, Z, Rxy, Phi, Rxyz. A given shape cannot be divided however on any axis. The general rule is that that divisions are possible on whatever axis that produces still known shapes as slices. The division of shapes should not be performed by TGeoShape::Divide() calls, but rather by TGeoVolume::Divide(). The algorithm for dividing a specific shape is known by the shape object, but is always invoked in a generic way from the volume level. Details on how to do that can be found in TGeoVolume class. One can see how all division options are interpreted and which is their result inside specific shape classes.
