| 33 | // Class Description: |
|---|
| 34 | // G4VisExtent defines a bounding box in a visualisable object's local |
|---|
| 35 | // coordinate system which includes the object. |
|---|
| 36 | // WARNING: it also attempts to support the concept of a bounding |
|---|
| 37 | // sphere. (This is used extensively in the G4 Visualisation System |
|---|
| 38 | // to calculate camera parameters, etc.) Be aware that this involves |
|---|
| 39 | // loss of information. Given a bounding box, one can calculate the |
|---|
| 40 | // bounding sphere; inverting this will produce a cube which *might* |
|---|
| 41 | // *not* include the object. E.g., a long thin object of length l |
|---|
| 42 | // will have a bounding sphere of diameter l; the corresponding cube |
|---|
| 43 | // will have side l/std::sqrt(3) so that the bounding sphere diameter is |
|---|
| 44 | // still l. Thus the long thin object will stick out of the cube. |
|---|
| 45 | // So, if you once use the concept of bounding sphere you must stick |
|---|
| 46 | // with it and abandon the concept of bounding box. |
