GAMGI Interfaces: Cell Create

# Cell Create

- Symmetry
- Volume
- Position
- Origin
- View

Define here the cell visual aspect.

### Faces

When the button Faces is down, the cell is represented as a solid object, that users can see from the outside or from the inside. This option is disabled in Projection, Rhombus and Sphere volumes (otherwise the filtering volume would hide the lattice inside).

When the button Faces is up, the cell is represented as a wired object, formed by lines connecting the vertices (or by circumpherences, in the Sphere representation).

### Nodes

When the button Nodes is up, the nodes are visible, otherwise they are hidden. This option is disabled for Projection volumes.

### Borders

Selecting None, no borders are shown in any volume representation. Selecting Edges, the outer line contours are shown but cell boundaries are hidden (as long as they are in the same plane, independently of the lattice parameters). Selecting Faces, all lines are shown, except those inside the volume representation (for Parallelepiped and Sphere volumes, Edges and Faces options behave in the same way).

Selecting All shows all the border lines, including those inside. This option is disabled when the button Faces is down, because in solid mode, internal borders cannot be seen from the outside and make it very difficult to analyze something from the inside. Options Faces and All are disabled in Parallelepiped and Sphere volumes, as there are no additional lines to represent in these representations, only the outer lines already shown with the option Edges. All options except Edges are disabled for Projection volumes.

At least one visual element, Nodes, Faces or Borders, must be visible when the cell is created, otherwise an error is flagged.

### R, G, B

The R, G, B entries define the cell color, from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0). It is used to draw the lines and nodes, in wired mode, and the solid faces, in solid mode. In the last case, lines and nodes are drawn using the current layer background color, to get a good contrast and eliminate the need to define yet another color.

### Scale

Set the cell size, including its child objects. Cell objects are scaled around the cell center. The visual representation of an object is always scaled by its own scale factor multiplied by the scale factor of all its parent objects until layer, inclusive.
