Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

New generic method to check shape navigation methods TGeoShape::CheckShape that can run a given test number from a test suite. Currently a single test implemented (see desctiption in TGeoShape::CheckShape). Fixed TGeoArb8::DistToPlane with respect to boundary crossing. Added possibility to divide assemblies according a pattern (still under development). This is the first step in being able to gave generic divided-like volumes without being forced to have a container shape - particularly useful in describing calorimeters.

From Andrei:
- Removed casting away constness in headers, and removed == and != between doubles in all geom code (Philippe's suggestion)
- Info messages suppressed now by the static TGeoManager::SetVerboseLevel(0). We should probably call this at the beginning of stressGeometry.cxx
- Fine tune in TGeoIntersection::DistFromInside() that solves inner boundary crossings in case the starting point is very close to boundary
- TGeoManager::FindInCluster() gives now priority (when selecting between MANY candidates) to the node that was proposed by FindNextBoundary()

From Andrei:

- TGeoUnion::DistFromInside() fixed to give the full distance to outside rather than the one from the current component.

From Andrei:
- Truncation errors better taken into account when propagating to boundaries.
- A fix for TGeoXtru::DistFromInside() in case propagation to outside fails.
- A very important protection in TGeoArb8 that checks if the vertices are defined clockwise. It posts an error message if this is not the case and automatically fixes the wrong shapes event if geometry is loaded from file.

From Andrei:
fixes an I/O problem for TGeoArb8: the data member fTwist is not persistent so it has to be recomputed when loading the geometry from file. Introduced custom Streamer that calls ComputeTwist() after reading. Affected safety computation for twisted TGeoArb8-s (3 shapes like this in alice) that in this case was wrongly assuming planarity of shape surfaces.

From Andrei:
there was an implicit dependency of TGeoMatrix by TGeoManager.h via TGeoNavigator.h->TGeoCache.h + few other bad dependencies like: TGeoMatrix included by TGeoNode.h via TGeoPatternFinder.h Hmm... I had to cleanup few inlines, introduce a transient matrix in TGeoNavigator (to recover the lost inlining speed) + add several #include "TGeoMatrix.h" allover where this was included and used via TGeoManager.h

TMath::Abs, TMath::Min, TMath::Max, TMath::Sign, TMath::Range
These functions are unfortunately not defined in a standard way in std::
This include is referenced by a new version of TMath.h.
As a result, TMath.h is back compatible with the previous version.
TMathBase.h is used in place of TMath.h in all the classes
that will go into the future miniCore library.
TMath.h and the TMath implementation will go into a new math sub-directory.
TString.h uses TMathBase.h instead of TMath.h.
As a result, it was necessary to include "TMath.h" in some classes
assuming that TMath was included via TString and using other functions
than the ones defined in TMathBase.h

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Andrei & Mihaela:
a diff containing the implementation of TGeoShape::Capacity. There are also
few other fixes (see below):
Mihaela:
New method:
Double_t TGeoShape::Capacity() const;
implemented for all supported shapes. The algorithms provide analytical computation of
shape capacity in [cm^3]. All algorithms are accurate with 2 exceptions:
- TGeoCtub : the formula is just an approximation due to the difficulties to integrate
over the phi angle in the general case.
- TGeoCompositeShape: the computation of the capacity is done by sampling, with an
accuracy of 1%.
Based on this method I extended the implementation of TGeoVolume::Weight(Double_t
precision, Option_t *option). The default value of option is now "va" meaning: verbose
+ analytical. Removing "a" from the default option performs computation of volume
weight using the old algorithm of sampling. I have checked the 2 ways of computing the
weight one against the other and they are consistent.
Andrei:
- fixed a memory leak related to TGeoShapeAssembly ownership
- fixed some tracking problems for assemblies (when the top volume was an assembly)

From Richard Maunder:
Changes to viewer infrastructure (TBuffer3D,TVirtualViewer3D) to
support:
i) Proper shape specific (sphere, tube, etc) descriptions in TBuffer3D
derived classes - c.f. abuse of raw tesselation blocks before.
ii) On demand filling of buffer sections as required by viewer.
iii) Support for local/master frame shapes descriptions & child object
rejection.
iv) Template/placed shapes ids - enabling viewer to detect/receive
common shapes once and just obtain the new position and id of the
duplicate.
Cleans up all producer (g3d/geom) code so no longer has an viewer
specific knowledge - Paint() methods replaced with
GetBuffer3D/FillBuffer3D methods which complete requested sections of
the buffer.
All viewer specific code now sits on the viewer implementation side of
TVirtualViewer3D. Added a TViewer3DPad class for performing the 3D draws
into pad. In future this should be merged with TView/TView3D possibly.
TBuffer3D is now stripped of functional code (aside from memory
management) and various viewer passback options there previously.
Enforced one way passing a const & to viewer.
Buffers (various types) are held as single static inside producer
function e.g. TGeoShape::GetBuffer3D (c.f. single generic buffer type
fetched from pad previously).
For g3d and geom shapes the top level geometry painter (TNode /
TGeoPainter) controlls painting process, requesting shapes to fill
buffer and passing to 3D viewer.
Exceptions are g3d's TPolyLine3D, TPolyMarker3D & TMarker3DBox. These
are 'standalone' shapes - no controlling 'painter' object. They still
implement Paint(), fill buffer and add to viewer directly.
3D viewer still held / created by pad - and pad has it's own viewer
object (TViewer3DPad).
NOTE:
1. Current scheme supports one 3D viewer only - pad, x3d or OpenGL. This
means that pad goes blank when x3d/OGL is spawned, and is updated again
when it is closed. To be revisited - need to support multiple viewers,
of multiple types - which implies explicit naming or pad controlling
enumeration.
2. OGL viewer now responds correct to modifications in pad, without
having to be reinvoked (as previously). x3d is still decoupled (as
previously) so does not rebuild - too difficult to get working.

From Andrei Gheata:
The diffs for the changes from Mihaela. They implement the SavePrimitive method for:
- all shapes
- materials, mixtures and media
- matrices
- TGeoVolume - just a first version
What is missing:
Divisions + manager metod to save:
- all geometry
- just the branch corresponding to one volume
The differences compared to g2root are that:
- when saving just a a branch just materials/media/matrices for that branch are created (module encapsulation)
- instead of creating objects with numerical arguments, the coresponding variables are defined and used.
e.g. instead of :
new TGeoBBox("name", 10.,20.,30); the generated code is:
dx = 10.;
dy = 20.;
dz = 30.;
pShape = new TGeoBBox("name", dx,dy,dz);
The diffs contain also 2 shapes with boundary-safe algorithms: TGeoPara and TGeoTrap

- TGeoMaterial/Medium - added Cerenkov properties by Andreas (for FLUKA)
- TGeoVolume.h, TGeoManager.k - added *TOGGLE* 's
- TGeoPhysicalNode - possibility to align a physical node. One can
define a physical node according a path, then change its local
transformation matrix OR shape - the corresponding branch is decoupled
from the logical tree and a new trackable branch is created. A
post-alignment check for overlaps can be perfomed for the aligned node.

From Andrei Gheata:
- computation of normals to all primitive shapes, except TGeoCompositeShape
- improved TGeoTorus algorithms
- ray tracing feature : works as TGeoVolume::Draw() except that the
volume is ray-traced according to current visualization settings. All
features from a normal drawing are preserved : picking, zooming,
rotating,... The time for producing the ray-traced image scales with the
surface of the current pad (in pixels) and to the number of visible
nodes on screen. The current image can be clipped with any other shape,
defined in the reference frame of the current drawn volume. It works like:
TGeoTubeSeg *clip = new TGeoTubeSeg(params...);
gGeoManager->SetClippingShape(clip);
someVolume->Raytrace();
...
gGeoManager->SetClipping(kFALSE/kTRUE); to disable/enable clipping.
If the clipping shape is changed, the old one is automatically deleted.

- TGeoManager::FindNormal(Bool_t forward=kTRUE) = global algorithm for
finding the normal to the next/previous crossed surface, from the
current global point/direction. The current point does not necessary
need to be close to the surface, and the normal direction is always
returned so that its dot product with the current direction is positive
defined. One can get the normal after its computation with:
Double_t *TGeoManager::GetNormal()
- Normal computation algorithms for box, arb8, trap, gtra, cone in the
corresponding shape classes.
- New primitive shape fully implemented, from visualization to
computation of distances (except the normal computation, missing also
for several other shapes). Class name: TGeoTorus, representing a torus
segment with :
- R - radius of the circle representing the torus axis
- Rmin - inner radius (like a donut having a hole in the middle)
- Rmax - outer radius (Rmin < Rmax < R)
- Phi1 - start phi
- Dphi - phi range
- Some unused obsolete methods removed from the TGeoShape class.
- modifications in TGeoIdentity default ctor to initialize gGeoIdentity
- TGeoMaterial::IsMixture(),
TGeoMaterial::FindDuplicateMaterial(const TGeoMaterial *mat)
- several other minor changes

New version from Andrei and Mihaela:
- several implementations of method Safety for shapes
- few bug fixes in safety computation (phi segmented shapes)
- volumes have now an unique ID that you can get with GetNumber()
- Mihaela implemented an overlap checker that can be called either for
all geometry :
TGeoManager::CheckOverlaps(Double_t ovlp=0.1) or just for a given
volume. OVLP is the lower overlapping limit. The checker looks for the
following errors in the geometry definition :
1 - nodes extruding their mother - can be visualised with
TGeoManager::DrawExtrusion(char *mother, char *node) which draws mother
in blue and extruding daughter in red
2 - ONLY brothers overlapping to each other - can be visualized with
TGeoManager::DrawOverlap(char *volume, char *node1, char *node2) - node1
will appear in red and node2 in blue.
These methods can be called only after CheckOverlaps() that prints the
list of overlaps. They are all in the context menu of both TGeoVolume
and TGeoManager.

From Andrei:
- all shape classes : changed the prototype for Safety() method.
Eliminated validity checking in Divide() methods that are now globally
handled by TGeoVolume::Divide(). Added methods
TGeoShape::GetAxisName/Range(Int_t iaxis) which are used by the new
global division mechanism.
- safety for TGeoTrap now computed (pcon, pgon not yet)
- TGeoVolume : eliminated unnecesarry Divide() prototypes. The new
Divide() prototype is backwards compatible (old macros works with it)
but supports an option in order to allow all G3 division types. More
description in TGeoVolume::Divide().
- TGeoManager : Only one prototype for G3-like divisions left,
supporting all G3 options and also being able to assign to the division
volumes a medium different than the one of the divided volume. New
FindNode(x,y,z) implemented. New IsSameLocation(x,y,z) with the same
functionality as GINVOL.

Several updates to the geometry pacjage by Andrei:
TGeoManager :
- added getter for current direction;
- dummy cache option by default
TGeoNodeOffset
- set the name for parametrized divisions; minor fix in allocating the
space for the name (safer now)
TGeoPatternFinder :
- the getter for the matrix of a divided node will return the updated
matrix (before one had to do TGeoNodeOffset::cd() first, now
TGeoNodeOffset::GetMatrix() does this in one go)
Shape classes :
- protection for wrong division range slightly modified

New version of TGeo classes from Andrei:
-TGeoManager - added G3-like prototypes for building geometry
-TGeoPatternFinder - added parameters of a division (fStart, fStep, fEnd)
-TGeoVolume - fix in TGeoVolumeMulti::AddVolume() to update existing
nodes for all volumes in list
several shapes supporting divisions - using TGeoVolumeMulti for divisions
-TGeoVoxelFinder - fixed dtor

From Andrei:
attached the last version, with bug fixes in tracking. Now you can do
lego plots for everything in alice. It does not do extra steps (except
very seldom in ITS in som very thin tubes - 1 extra step to cross). Much
more stable. I temporarly disabled TGeoVolume::CheckGeometry from the
context menu of volumes since it seems to have a bug that I need to fix.
Much better version in computing distances.

Upgrade of the geom classes by Andrei:
- improvements in the drawing mechanism (nodes can also be made
invisible, having higher priority than volumes;
- possibility of simple phi cut in TGeoManager::SetPhiRange(phimin, phimax)
- by default the phi range is (0, 360) - no cut performed
- setting different values for phimin, phimax will make invisible the
nodes having the origin in this range;
- documentation updated for TGeoArb8 class (picture in /gif directory)

new version of the geometry package from Andrei:
- bug fix in the destructor of TGeoPatternCylPhi
- several modifications in the default constructors of shapes.
- several corrections and "v" feature added to I/O
- removed base class for finders
Now you can save voxels and retreive them with no problem. You can use :
gGeoManager->Export("filename", "", "v") to do that. The size of files
without/with voxelization are :
Exp no voxels saved voxels saved
ALICE 404227 719703
CMS 550440 1275590
ATLAS 1858198 3335166
Be careful, the files TGeoFinder.h and TGeoFinder.cxx have been removed.
Suggest doing:
rm geom/src/*.o geom/src/G__*

New version of the geometry package by Andrea & Mihaela Gheata
New features:
-I/O for all geometry classes. For example, to save/restore a geometry structure,
TFile f("mygeom.root","recreate");
gGeoManager->Write("mygeom");
and to read it back;
TFile f("mygeom.root");
f.Get("myGeom");
gGeoManager->CloseGeometry();
-Composite shapes fully implemented (no visualisation yet).
A composite shape is built out of basic shapes and transformations via
a simple formula mechanism, eg assuming a TGeoTube "tub1" and a TGeoMatrix "r1",
we can build a composite shape with:
TGeoCompositeShape *comp = new TGeoCompositeShape("comp",formula); where
char* formula="tub1+tub1:r1"
This will create the union of a tube with itself rotated.
The operators recognized by the geometry formula parser are "+","-","*"
for union, subtraction and intersection respectively. The colon ":" can be
used to specify a transformation for a given component.
-The voxelisation in cylindrical coordinates added as an optional optimisation
algorithm.
-Some bug fixes and several improvements in the tracking-related algorithms.

Change the default argument value for the lastybin/lastxbin when
making Projections or Profiles from 9999 to -1.
The previous default value was not acceptable for 2-d or 3-d histograms
having more than 10,000 bins along Y.
