Function bounding_box

Returns a function of type (string, string) → number, for getting the specified Shape's bounding box coordinates.

Its first parameter must be "x", "y", or "z", indicating the coordinate axis.

Its second parameter must be "min" or "max", indicating the minimum or maximum bounding box coordinate respectively.

For example, if a sphere of radius 0.5 is centred at (0.5, 0.5, 0.5), its minimum bounding coordinates will be (0, 0, 0), and its maximum bounding coordinates will be (1, 1, 1).

// Sample usage
const getter_function = bounding_box(sphere(silver));
display(getter_function("y", "max")); // Displays 1, the maximum y coordinate
