---|
| 116 | for properly handling location on z-axis and in the frame origin. |

| 135 | - Updated implementation of SurfaceNormal(p) to get consistence with |
---|
| 136 | Inside(p) functions for the treatment of phi/theta surfaces. |
---|
| 137 | They are treated now in both functions in terms of kAngTolerance. |
---|
| 138 | The reason is that historically SurfaceNormal(p) was using only |
---|
| 139 | kCarTolerance for estimation of shortest distance to a surface. Now, |
---|
| 140 | following the new updated specification, the surface selection is made |
---|
| 141 | according to Inside(p) approach (as kSurface is selected), i.e. - for |
---|
| 142 | phi/theta surfaces in terms of kAngTolerance. |

---|
| 172 | on request and stores for future access. A null pointer means "not |
---|
| 173 | available". |
---|
| 174 | |
---|
| 175 | Sep 22, 2004 V.Grichine geom-csg-V06-02-04 |
---|
| 176 | - Added specific implementation of GetCubicVolume() for all CSG solids. |

---|
| 468 | Apr 11, 00 J. Allison |
---|
| 469 | |
---|
| 470 | - Removed implementations of GetExtent in most sub-classes of G4VSolid (a |
---|
| 471 | default implementation exists in G4VSolid). |
---|
| 472 | - All implementations of DescribeYourselfTo (G4VGraphicsScene& scene) const |
---|
| 473 | now correctly written: scene.AddThis(*this). |

| 475 | Apr 05, 00 G. Cosmo geom-solids-csg-V01-01-01 |

---|
| 481 | - Moved to "specific" the following classes: |

---|
| 487 | specific/test |
---|
| 488 | - Moved generic tests "SBT" and "Fred" one level up to solids/test. |

| 495 | Mar 22, 00 D. Williams |
---|
| 496 | - G4PolyhedraSide.cc: fixed bug in G4PolyhedraSide::Normal(...). |
---|
| 497 | The method Normal(...) (used by G4VCSGfaceted::SurfaceNormal) was not |
---|
| 498 | filling in the argument bestDistance. This fixes a bug observed in |
---|

---|
| 506 | - Minor fixes to unit tests to make them up-to-date with recent |
---|
| 507 | development versions (already included in tag geometry-V01-00-00a). |

---|
| 511 | Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04 |

| 534 | May 18, 99 David Williams |
---|
| 535 | - Replaced 1/DBL_MAX with DBL_MIN (valid correction, seen in tests for STL) |
---|
| 536 | in G4PolyPhiFace.cc, G4PolyconeSide.cc and G4PolyhedraSide.cc |
---|
| 537 | |
---|
| 538 | Apr 29, 99 David Williams |
---|
| 539 | - G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified: |
---|
| 540 | 1. Implemented correct copy constructors and assignment operators. |
---|
| 541 | 2. Fix some leaks for tracks that pass exactly through an edge. |
---|
| 542 | Some leaks still remain: particularly if a track passes through |
---|
| 543 | a corner and between the curved edges of G4Polycone. |
---|
| 544 | 3. G4Polyhedra argument numSide changed to G4int (from G4double) |
---|
| 545 | |
---|
| 546 | Apr 13, 99 Vladimir Grichine and Simone Giani |
---|
| 547 | - Minor consistency fix to 8 basic CSG solids: |
---|
| 548 | Tolerance used in calculation of extent but not in one place, |
---|
| 549 | and not another - this tripped up the client code. |
---|
| 550 | |
---|
| 551 | Feb 16, 99 David Williams |
---|
| 552 | - Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in |
---|
| 553 | test/testG4Polycone and missed in below. |
---|
| 554 | - Updated definition of DistanceToIn(p) and DistanceToOut(p) to |
---|
| 555 | return zero when the point p is on the surface of the solid. |
---|
| 556 | |
---|
| 557 | Feb 12, 99 David Williams |
---|
| 558 | - src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by |
---|
| 559 | test/testG4Polycone. |
---|
| 560 | |
---|
| 561 | Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu) |
---|
| 562 | - I've committed new versions of the CSG Polycone and Polyhedra in the |
---|
| 563 | geant4 repository, including a new utility class called |
---|
| 564 | G4ReduciblePolygon. The new versions fix several subtle bugs which my |
---|
| 565 | "test3" batch geometry testing code uncovered. In addition, the new class |
---|
| 566 | G4ReduciblePolygon is used to run strict tests on the validity of input |
---|
| 567 | parameters. |
---|
| 568 | To fix a bug in Polyhedra, I had to back out some fancy code that |
---|
| 569 | allowed it to calculate intersections at a speed that was independent of |
---|
| 570 | the number of sides. The new version now runs at a speed proportional to |
---|
| 571 | the number of sides, and is thus much slower for polyhedras with many |
---|
| 572 | sides. I can fix this, but I thought it would be best to get the bug fixes |
---|
| 573 | in as soon as possible. |
---|
