Grid X and Y
The grid x and y coordinate indicate the location of the department node in the hexagonal adjacency graph. The y-axis is oriented downwards and left along the axis of the hexagonal graph, i.e., y coordinates increase from the top of the screen to the bottom. The x coordinates increase from left to right.
Layout X and Y
The layout x and y coordinate indicate the location of the department in the two_ dimensional layout matrix. The y-axis is oriented downwards, i.e., y coordinates increase from the top of the screen to the bottom. The x coordinates increase from left to right.
Origin X and Y
The origin x and y of a departments are the horizontal (width) and vertical (depth) coordinates of the top left corner of the department relative to the top left corner of the building. The x coordinate increases from left to right, the y coordinate increases from top to bottom of the screen. The coordinates are real numbers, i.e. they can have fractional values. The department located in the top left corner of the building has by definition origin x and y coordinates equal to (0, 0). The units are the same as for the building dimensions.
Extent X and Y
The x and y extent of a department are the horizontal (width) and vertical (depth) dimensions of the smallest rectangle that completely encloses the department. For rectangular shaped departments this is equal to the department dimensions. The dimensions are real numbers, i.e. they can have fractional values. The units are the same as for the building dimensions.
Centroid X and Y
The x and y centroid coordinates of a department are the horizontal and vertical coordinates of the center of gravity of the department. For rectangular shaped departments the centroid is located halfway between the two boundaries. The coordinates are real numbers, i.e. they can have fractional values. The units are the same as for the building dimensions.
Area
Some algorithms might create a department with a continuous area smaller (or larger) than the specified area. The actual continuous area is computed and shown on this page.
Perimeter
The actual perimeter length of the department is shown on this page.
Shape Ratio
The shape ratio of a department is the maximum of the depth to width and width to depth ratio of the smallest rectangle that completely encloses the department. For example the shape ratio of a square is one and the shape ratio of a three by one rectangle is equal to three.
Perimeter Ratio
The perimeter ratio of a department is the ratio of its actual perimeter length divided by the perimeter length of a square department with the same area. For example the perimeter ratio of a square is one and the perimeter ratio of a four by one rectangle is equal to 1.25. A higher value indicates a department with a more convoluted shape. For rectangular departments there exists a one to one correspondence between the perimeter ratio of a department and the shape ratio. In Spiral the perimeter ratio is only displayed as information for the user.
