Class Description

 dummy ctor

 constructor.

 constructor.

 ctor with an array of parameters
 param[0] = dx1
 param[1] = dx2
 param[2] = dy
 param[3] = dz

 destructor

 compute bounding box for a trd1

 test if point is inside this shape
 check Z range

 compute distance from inside point to surface of the trd1

 get the most visible corner from outside point and the normals

 get the opposite corner of the intersected face

 compute distance from outside point to surface of the trd1

 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.

--- Divide this trd1 shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume in case of Y divisions. For Z divisions just
 return the pointer to the volume to be divided. In case a wrong
 division axis is supplied, returns pointer to volume that was divided.

 Get range of shape for a given axis.

--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

 Fills real parameters of a positioned box inside this. Returns 0 if successfull.

 in case shape has some negative parameters, these has to be computed
 in order to fit the mother

 print shape parameters

 computes next intersection point of curve c with this shape

 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.

 set trd1 params in one step :

 set vertex of a corner according to visibility flags

 create arb8 mesh points

 create arb8 mesh points

 fill size of this 3-D object
