32 | // Class description: |
---|
33 | // |
---|
34 | // Base class for parameterisations that use information from the parent |
---|
35 | // volume to compute the material of a copy/instance of this volume. |
---|
36 | // This is in addition to using the current replication number. |
---|
37 | // |
---|
38 | // Notes: |
---|
39 | // - Such a volume can be nested inside a placement volume or a parameterised |
---|
40 | // volume. |
---|
41 | // - The user can modify the solid type, size or transformation using only |
---|
42 | // the replication number of this parameterised volume. |
---|
43 | // He/she is NOT allowed to change these attributes using information of |
---|
44 | // parent volumes - otherwise incorrect results will occur. |
---|
45 | // Also note that the usual restrictions apply: |
---|
46 | // - the mother volume, in which these copies are placed, must always be |
---|
47 | // of the same dimensions |
---|
