Detailed Description

TTreeTransform is the full representation of a tree's transform

x'= fUniformScaling*fRotation*fXYZScaling*(x-fHotPoint) + fOffset

Example (in 1D):

   
    Parent          fOffset              H.P.           fHotPoint           Local
    Zero +------------------------------> + <-----------------------------+ Zero
