A collection of non-parallel planes.
This class implements the geometry methods of a set of non-parallel planes. A position is considered to be in the 'th region of a plane collection if it is inside the 'th plane (i.e. the point is on that side of the plane to which the plane normal points to) but outside the 'st plane. Note that a set of non-parallel planes does not form a well defined set of regions in general. The EGS_PlaneCollection class is therefore only meant to be used for construction of composite geometries where other geometrical structures restrict the extent of the geometry to the portion of space where the non-parallel planes do not intersect and therefore the regions formed by the plane collection are well defined.
The additional keys needed to define a plane collection are
library = egs_planes type = EGS_PlaneCollection normals = ax1,ay1,az1 ax2,ay2,az2, ... positions = p1 p2 ...
where there are floating number inputs for the normals
key and floating number inputs for the positions
key needed to define a collection with planes defining regions.
An example of the use of a plane collection is found in the photon_linac.geom example geometry file. See also Example geometries
A simple example:
