A template class for modeling pyramids.
This template class models pyramids with specializations for pyramids having their bases in the X-, Y-, Z- and any plane. The class can be used to model "open" pyramids (pyramids that extend to infinity in the direction pointing from the tip of the pyramid towards the plane used to define the pyramid base) or closed pyramids. The pyramid bases can be arbitrary closed polygons. Pyramid geometries have a single region (inside the pyramid). They are defined via the following set of keys:
library = egs_pyramid type = EGS_PyramidX or EGS_PyramidY or EGS_PyramidZ or EGS_Pyramid points = list of 2D or 3D positions tip = Ox, Oy, Oz # 3D position of the tip of the pyramid. closed = 0 or 1 # optional
As with prisms , when a X-, Y- or Z-pyramid 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_Pyramid 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_Pyramid is rejected. The tip
key defines the 3D position of the tip of the pyramid. The closed
key is optional. When missing or set to 0, the pyramid is open, otherwise it is closed by the plane in which the pyramid base is defined.
The pyramid.geom
example geometry file demonstrate the use of a pyramid object.
A simple example:
:start geometry definition: :start geometry: name = my_pyramid library = egs_pyramid type = EGS_PyramidZ points = 1 1 -1 1 -1 -1 4 -1 tip = 0 0 2 closed = 1 :start media input: media = water :stop media input: :stop geometry: simulation geometry = my_pyramid :stop geometry definition:

const EGS_Vector & | Xo, | ||
bool | O = true , |

const string & | N = "" |

) |
Construct a pyramid using P as the base polygon and Xo as the position of the tip.
If O is true
, the pyramid is open (i.e. extends to infinity in the direction from the tip towards the pyramid base), otherwise it is closed by the base polygon.
