|

| 16 | *
|
|---|
| 17 | * Shapes are present for denoting a specific region of the simulation domain.
|
|---|
| 18 | * There are four primitive types present:
|
|---|
| 19 | * - Sphere
|
|---|
| 20 | * - Ellipsoid
|
|---|
| 21 | * - Cuboid
|
|---|
| 22 | * - Cylinder
|
|---|
| 23 | *
|
|---|
| 24 | * Note that all may be modified (shrink/grow, rotate, morph) via an arbitrary
|
|---|
| 25 | * matrix.
|
|---|
| 26 | *
|
|---|
| 27 | * The shapes are for the moment only used within \ref descriptors to specify
|
|---|
| 28 | * a specific subset of atoms, here that reside in a certain region of the
|
|---|
| 29 | * simulation domain.
|
|---|
| 30 | *
|
|---|
| 31 | * \todo There is a certain relation between Tesselation and Shape. Hence, later
|
|---|
| 32 | * Tesselation shall itself be a Shape, i.e. that describes a certain region in
|
|---|
| 33 | * space, here via a tesselated mesh.
|
|---|
| 34 | *
|
|---|
| 35 | * \section shapes-constructive-geometry Constructive Geometry
|
|---|
| 36 | *
|
|---|
| 37 | * Again, Shapes can be joined via boolean operators:
|
|---|
| 38 | * - add
|
|---|
| 39 | * - or
|
|---|
| 40 | * - not
|
|---|
| 41 | *
|
|---|
| 42 | * And thus are a very powerful concept called constructive geometry.
|
|---|
| 43 | *
|
|---|
| 44 | * E.g. a shape can be used like this
|
|---|
| 45 | * \code
|
|---|
| 46 | * Cuboid(Vector(0,0,0), Vector(2,2,2)) && !Sphere(Vector(1,1,1), 1.)
|
|---|
| 47 | * \endcode
|
|---|
| 48 | * which would match any object within the cuboid from (0,0,0) to (2,2,2)
|
|---|
| 49 | * that is not in the unit sphere at (1,1,1).
