node

Description

A node element encodes a single 3-dimensional point in a spatial link.

The character data of this XML element should consist of three floating point numbers, representing the x, y and z coordinates of the point.

Regina writes the individual coordinates using hexadecimal floating point format to ensure no loss of precision; however, any standard floating point format may be used.

Example

The following XML snippet represents the point (-5.00478, -2.20299, 0.670091), using hexadecimal floating point format to represent the individual coordinates.

<node> -0x1.404e48p+2 -0x1.19fb74p+1 0x1.57163p-1 </node>
