Class Description

 Geometrical transformation package





/*

*/

 Returns true if no rotation or the rotation is about Z axis

 Get total size in bytes of this

 The homogenous matrix associated with the transformation is used for
 piling up's and visualization. A homogenous matrix is a 4*4 array
 containing the translation, the rotation and the scale components

          | R00*sx  R01    R02    dx |
          | R10    R11*sy  R12    dy |
          | R20     R21   R22*sz  dz |
          |  0       0      0      1 |

   where Rij is the rotation matrix, (sx, sy, sz) is the scale
 transformation and (dx, dy, dz) is the translation.

 convert a point by multiplying its column vector (x, y, z, 1) to matrix inverse

 convert a vector by multiplying its column vector (x, y, z, 1) to matrix inverse

 convert a point by multiplying its column vector (x, y, z, 1) to matrix inverse

 convert a point by multiplying its column vector (x, y, z, 1) to matrix

 convert a point by multiplying its column vector (x, y, z, 1) to matrix

 convert a point by multiplying its column vector (x, y, z, 1) to matrix

 print the matrix in 4x4 format

 If no name was supplied in the ctor, the type of transformation is checked.
 A letter will be prepended to the name :
   t - translation
   r - rotation
   s - scale
   c - combi (translation + rotation)
   g - general (tr+rot+scale)
 The index of the transformation in gGeoManager list of transformations will
 be appended.
