0061 the Scientific Linux CERN 3 (SLC3) distribution (based on RedHat Linux
0062 Enterprise 3) and also with RedHat 7.3.
0063 Versions of Geant4 have also been compiled successfully on other

0123 <UL>
0124 <LI>The default compiler distributed by Red Hat since release 7.0 is
0125 NOT supported and not considered reliable for running a Geant4-based
0126 application. In more than one test case, binaries produced by gcc-2.96
0127 have shown incorrect behavior, either due to wrong order of
0128 initialisation of static data in memory or to bugs in the system
0129 <TT>iostream</TT> classes, problems which apparently have all been
0130 solved in more recent versions of the compiler (3.X series).<BR>
0131 For information, gcc-2.96 is a compiler that has never been

0188 <H2>7. Major items for migration of user code</H2>
0189
0190 Some migrations are necessary in different areas of the user code in
0191 order to upgrade from release 6.2 to release 7.0,
0192 a full recompilation and/or reinstallation of libraries and user
0193 applications is moreover required.
0194
0195 <P> </P>
0196 <B>Direct usage of <TT><cmath></TT> for standard mathematical functions</B>
0197 <P> </P>
0198 In this release the Geant4 code makes now direct usage of <TT><cmath></TT>
0199 for standard mathematical functions. All direct/indirect inclusions of
0200 <TT><math.h></TT> have been removed.<BR>
0201 To be compliant with this migration, the user code should be modified as well,
0202 by adopting either one of the following approaches:
0203 <UL>
0204 <LI>Put in front of the following standard mathematical functions the <TT>std::</TT>
0205 prefix for the namespace:
0206 <PRE>
0207 pow(), exp(), sqrt(), log(), log10(), sin(), cos(), tan(),
0208 sinh(), cosh(), tanh(), asin(), acos(), atan(), atan2(),
0209 ceil(), floor(), fabs(), fmod(), frexp(), ldexp(), modf()
0210 </PRE></LI>
0211 <LI>Alternatively, for places where code readability is a concern, add in source
0212 files (not headers or inline methods, and after the headers inclusions), the
0213 statement:
0214 <PRE>
0215 using namespace std; </UL>
0216 </PRE>
0217 </UL>
0218 As part of this migration also standard headers like:
0219 <PRE>
0220 <math.h>, <limits.h>, <stdlib.h>
0221 </PRE>
0222 are no longer indirectly included. This may require the user code to include
0223 them if/where necessary.<BR>
0224 To be noticed also that this migration involves also the <I>removal</I> of
0225 usage of the ad-hoc template function originally defined in CLHEP:
0226 <PRE>
0227 T abs(T)
0228 </PRE>
0229 So the definition of this function will not be any longer available in a
0230 indirect way. The standard mathematical function:
0231 <PRE>
0232 std::abs()
0233 </PRE>
0234 will have to be used instead.
0235
0236 <P> </P>
0237 <B>New Installation procedure for the <TT>Configure</TT> script</B>
0238 <P> </P>
0239 The installation procedure of the kernel libraries using the <TT>Configure</TT> script
0240 has changed. It is now required to specify the final area of installation for the
0241 libraries and sources; libraries are now first built in the local directory
0242 where the source has been downloaded and unpacked; and will be later-on installed
0243 in the specified installation area (requiring <TT>root</TT> priviledges if
0244 necessary).
0245 See the <A href="http://cern.ch/geant4/G4UsersDocuments/UsersGuides/InstallationGuide/html">Installation
0246 Guide</A> for the details.
0247
0248 <P> </P>
0249 <B>Migration for usage of the <TT>G4VParticleChange</TT> class</B>
0250 <P> </P>
0251 An interface change to the class <TT>G4VParticleChange</TT> is implemented
0252 in Geant4 7.0. Advanced users, who have implemented a physics process should
0253 be aware that the following methods have been removed:
0254 <PRE>
0255 void SetTrueStepLength(G4double truePathLength);
0256 void SetLocalEnergyDeposit(G4double anEnergyPart);
0257 G4TrackStatus GetStatusChange() const;
0258 void SetStatusChange(G4TrackStatus status);
0259 void SetSteppingControl(G4SteppingControl StepControlFlag);
0260 void SetParentWeight(G4double);
0261 </PRE>
0262 They have been replaced by the following methods, respectively:
0263 <PRE>
0264 void ProposeTrueStepLength(G4double truePathLength);
0265 void ProposeLocalEnergyDeposit(G4double anEnergyPart);
0266 G4TrackStatus GetTrackStatus() const;
0267 void ProposeTrackStatus(G4TrackStatus status);
0268 void ProposeSteppingControl(G4SteppingControl StepControlFlag);
0269 void ProposeParentWeight(G4double);
0270 </PRE>
0271 For the detailed list of all interface changes involved in <TT>G4VParticleChange</TT>,
0272 please consult:

0274
0275 <P> </P>
0276 <B>Step limitation</B>
0277 <P> </P>
0278 A user now needs to change his/her code, in order to limit the step size of a
0279 particle -- when using the class <TT>G4UserLimits</TT> to limit the step.
0280
0281 Up to the previous release, step limitation due to the maximum step length
0282 of <TT>G4UserLimits</TT> was directly done by <TT>G4SteppingManager</TT>,
0283 while all other limits (<TT>maxTrackLength</TT>, <TT>maxStepNumber</TT>,
0284 <TT>MinKinEnergy</TT> and <TT>minRemainRange</TT>) were dealt by
0285 <TT>G4UserSpecialCuts</TT> process. To solve this inconsistency,
0286 to simplify the majority of applications which do not utilize the step limitation,
0287 and to give more usability to the user, we introduce a new
0288 process <TT>G4StepLimiter</TT> and move the step limitation procedure in
0289 <TT>G4SteppingManager</TT> to this new process.
0290 <UL>
0291 <LI>The new process, <TT>G4StepLimiter</TT>, limits the step size specified by
0292 <TT>G4UserLimits</TT>, but will not kill a track.</LI>
0293 <LI><TT>G4UserLimits</TT> class is kept as it is, and can specify all limits as before.</LI>
0294 <LI><TT>G4UserSpecialCuts</TT> is kept as it is. This process kills
0295 a track once the track comes to a limit specified by <TT>G4UserLimits</TT> (as
0296 it did previously). This provides the user the ability
0297 to impose one or more kinds of "tracking cuts".</LI>
0298 <LI>Given no process took place for max step length limitation in the old design,
0299 <TT>G4StepPoint::GetProcessDefinedStep()</TT> method used to return <TT>NULL</TT>.
0300 In the new scheme, if a step is limited by the maximum step
0301 length limitation, this method now returns a valid pointer of <TT>G4StepLimiter</TT>
0302 process.</LI>
0303 </UL>
0304 The user who is using the step length limitation MUST include the new <TT>G4StepLimiter</TT>
0305 process in the physics-list explicitly. This new process may be assigned only to the
0306 selected particle types (e.g. only to the charged particles) instead of setting it to
0307 all particle types.<BR>
0308 No change is required for the user who is NOT using <TT>G4UserLimits</TT> for the
0309 purpose of maximum step limitation.
0310
0311
0312 <P> </P>
0313 <B>Killing of a particle</B>
0314 <P> </P>
0315 An advanced user who has created a process with a continuous component
0316 ('AlongStep' action) that can kill or bring a particle to a rest will need to
0317 review their process implementation.
0318
0319 Energy-loss processes no longer change the track status of a charged particle
0320 as part of their <TT>AlongStepDoIt()</TT> action.
0321 For a user-defined process with a "continuous" component,
0322 in order to stop (and thus either kill or bring to a rest in an 'alive' state)
0323 a particle in its <TT>AlongStepDoIt()</TT> method,
0324 it is now necessary to propose zero kinetic energy for the particle.
0325 Alternatively a process can contribute to the particle arriving at zero energy,
0326 as a result of the action of two or more processes, e.g. energy loss and
0327 propagation in an electric field (in the transportation process).
0328
0329 Once a particle has zero (or less) proposed energy, it is brought to a rest
0330 and its energy is set exactly to zero.
0331 If the particle can decay, can be annihilated or generally has one or more
0332 'AtRest' actions, then another step will be performed that calls these;
0333 else, the particle is killed.
0334 The discrete component (or 'PostStep' action) of a process will not be
0335 performed once the particle has come to a stop.<BR>
0336 <I>Note</I>: the case of a particle that comes to a rest in a field and is
0337 then re-accelerated, is not supported at this time.
0338
0339
0340 <P> </P>
0341 <B>Future migration for <TT>G4GeneralParticleSource</TT> class</B>
0342 <P> </P>
0343 A 'tree-structured' command format is implemented in this release for
0344 <TT>G4GeneralParticleSource</TT>. The old UI commands have been kept
0345 for backward compatibility but will be removed in the future.<BR>

0829 </PRE></LI>
0830 <LI>Added auxiliary edge visible flag to <TT>G4ViewParameters</TT> and a new
0831 command, <TT>/vis/viewer/set/auxiliaryEdge</TT>. (Auxiliary edges are not
0832 genuine edges of the volume. They may be in a curved surface made
0833 out of polygons, for example, or in plane surface of complicated
0834 shape that has to be broken down into simpler polygons.
0835 <TT>HepPolyhedron</TT> breaks all surfaces into triangles or quadrilaterals.
0836 There will be auxiliary edges for any volumes with a curved surface,
0837 such as a tube or a sphere, or a volume resulting from a Boolean
0838 operation. Normally, they are not shown, but sometimes it is useful
0839 to see them. In particular, a sphere, because it has no egdes, will
0840 not be seen in wireframe mode in some graphics systems unless this

0852 const G4VisAttributes* pVA =
0853 fpViewer -> GetApplicableVisAttributes (v.GetVisAttributes ());

0855 where v is the visible object (polyline, circle, polyhedron, etc.).</LI>
0856 <LI>Get view parameters that the user can force through the vis

0859 G4ViewParameters::DrawingStyle drawing_style = GetDrawingStyle (pVA);
0860 G4bool isAuxEdgeVisible = GetAuxEdgeVisible (pVA);
0861 </PRE>
0862 Most developers do this anyway, so the removed routine was redundant
0863 and resulting code is more efficient and transparent.<BR>
0864 To get colour, the developer can pick up directly from the vis attributes,
0865 pVA, obtained as above:
0866 <PRE>
0867 const G4Colour& c = pVA -> GetColour ();
0868 </PRE>
0869 or use a slightly less efficient method:
0870 <PRE>
0871 const G4Colour& c = GetColour (v);
0872 </PRE>
0873 where v is the visible object.<BR>
0874 Note that for text, the developer must use a different procedure,
0875 since the default text colour is determined by the default text vis
0876 attributes, which may be specified independent of default vis attributes
0877 of other types of visible objects. A function, <TT>GetTextColour()</TT>,
0878 is provided and the recommended use is:
