The BorderNode can be used to create borders based on noise values. For every requested value it checks the neighbours with a distance of width. If a neighbour value lies between top and bottom its distance or 1 will be returned.
| noise | The noise value to create borders. |
| width | The width to check for neighbours. Notice: high values are leading to many neighbour checks. This can impact performance significantly. |
| top | The top value to take as a border source. Usually between -1 and 1. Higher than bottom. |
| bottom | The bottom value to take as a border source. Usually between -1 and 1. Lower than top. |
| -1 values for non borders. Everything else is a border. |
