Point

Introduction of a normal point: 0001
Five bits introduction for a point with an empty position vector ($point(())$): 00010
Five bits introduction for a point with no position vector ($point()$): 10010

For the description of the point element see section 9.2 on page .

Normal points contain a position vector (see 21.3.1). The number of vector elements is determined by the number of dimensions respectively elements in the domain for dimensions ("dim"). The bits per position vector element is determined by the particular element of the domain for the dimensions ("dim") or by the domain variables ("variable") (see section 21.2.4 on page ).

The individual vector elements follow directly after the introduction of the point.

Points with an empty or without a position vector does not contain any bits for the position vector. For these points there are only the 5 bits of the respectively introduction.

Example: A point is encoded with the position vector (2, 10). The multimedia object has two dimensions. For both dimensions, 5 bits are needed, there are natural numbers.

• introduction point: 0001
• first position vector element (leading 0 for: "vector element is a value") 2 : 0 00010
• second position vector element (leading 0 for: "vector element is a value") 10 : 0 01010
• coded point object (first bit in front): 1000010000010100
