Creating and using dynamic vector classes

A device may store a data structure including information identifying a geometric relationship between first and second coordinate values of a first data type. The data structure may also include a first array of a first length that includes the first coordinate value located at a position identifiable by a reference value. The data structure may also include a second array of a second length that includes the second coordinate value located at a position identifiable by the reference value. The data structure may also include a third array of a third length that includes an attribute value of a second data type, located at a position identifiable by the reference value. The device may receive an indication that one of the lengths is to be modified, and may modify the data structure so that the first length, the second length, and the third length are equivalent.
