Detailed Description
template<class T>
class EGS_PrismT< T >
A class for modeling prisms.
This template class is used to model prisms with specializations for prisms having their bases in the X-, Y-, Z- and any plane. It can be used to model "open" prisms (prisms that extend to infinity along the axis perpendicular to the prism base) or closed prisms. The prism bases can be arbitrary closed polygons. Prism geometries have a single region (inside the prism). They are defined via the following set of keys:
library = egs_prism type = EGS_PrismX or EGS_PrismY or EGS_PrismZ or EGS_Prism points = list of 2D or 3D positions closed = two inputs
When a X-, Y- or Z-prism is being constructed the list of inputs for the points key is considered to be a list of 2D positions in the X-, Y- or Z-planes through the origin (and therefore the number of floating point numbers input must be even). When a EGS_Prism object is constructed, the list of inputs for the points key is considered to be a list of 3D positions (and therefore, the number of floating point numbers input must be divisible by 3). In this case, all points must be on a single plane, otherwise the construction of an EGS_Prism is rejected. The closed key is optional and if missing, the prism becomes "open". If present, the two inputs define the distance from the top and bottom prism plane to the plane used to define the polygon. Note that at least 3 different 2D or 3D positions are required for the points key in order to construct a prism. Also note that if the last point of the polygon is not the same as the first point, the polygon is automatically closed.
A simple example:
:start geometry definition:
:start geometry:
name = my_prism
library = egs_prism
type = EGS_PrismZ
points = 1 1 -1 1 -1 -1 4 -1
closed = 1 4
:start media input:
media = water
:stop media input:
:stop geometry:
simulation geometry = my_prism
:stop geometry definition:
